Plants belonging to the Rhododendron subgenera Pentanthera (deciduous) and Tsutsusi and Azaleastrum (evergreen) are called azaleas. Azalea belongs to family Ericaceae. Azaleas are one of the favourite ornamental plants used by home owners and professional landscapers. They are used as foundation, accent, individual specimen plants, and as mass plantings. Azaleas are good companion plants, working well in designs with many trees, shrubs and ground covers, offering a variety of landscape options. Azaleas can be found in all ranges of colours, from delicately pink-tinged white to strong, bright red, and there are species that has the startling colour of flame. Its bold colour scheme has caused people to carry it far and wide, for use wherever a sudden note in strong hue is appropriate among the milder expressions of the rest of the flowers. The evergreen azalea, Rhododendron simsii Planch., is one of the most important pot plants in Western Europe and the USA. The breeding history of this vegetatively propagated plant is a relatively short one, and breeding has been focused on flower characters because the public is continually asking for new flower colours and flower types.

ORIGIN AND DISTRIBUTION

Nevertheless, very little was known about the origin and the ancestor species used for this important ornamental crop. Rhododendron simsii, the species that is accepted to be the main ancestor, originates from hilly areas in China (Chang Jiang valley), Thailand, Laos and Burma. Apart from R. simsii, at least three other species from the Tsutsusi subgenus, from South-Asia and Japan, might have contributed: R. indicum, R. x mucronatum (Blume) G. Don and R. scabrum (Heursel, 1999).

From a floricultural viewpoint, azaleas are firstly divided into the two broad categories of deciduous and evergreen plants. The former, notoriously more rustic, have North American, Caucasian, and Asian origins, and are classified in the subgenus Pentanthera G. Don, whereas the latter derive exclusively from Asian species and are classified in the subgenus Tsutsusi (Sweet) Pojarkova (Chamberlain and Rae, 1990). Within the evergreen azaleas at least four more or less well defined groups of cultivars are distinguished according to their traditionally recognized most important ancestor: pot or Belgian azaleas (R. simsii Planch. putative hybrids), Hirado azaleas (R. scabrum G. Don putative hybrids), Kurume azaleas [putative hybrids of R. kiusianum Makino var. kiusianum and var. sataense (Nakai) D.F. Chamb. and R. kaempferi Planch.] and Satsuki azaleas [putative mutants or hybrids of R. indicum (L.) Sweet and R. eriocarpum (Hayata) Nakai]. The Hirado, Kurume and Satsuki groups are often referred to as Japanese azaleas because of their geographical origin (Scariot et al., 2007).

Bael [Aegle marmelos (L) Correa.], a native fruit of religious importance, is well known to the Indian people for its nutritional and medicinal values. Leaves are used as sacred offering to ‘Lord Shiva’. All parts of plant viz., leaves, roots, bark, fruits, seeds etc. are used in preparation of various Ayurvedic medicines. Bael fruit is rich in protein, fat, minerals (Ca and Fe) and vitamins (riboflavin, β carotene and Vitamin C). Fruits are used to improve the digestive system and to cure stomach diseases. Fruits can be processed into various beverages and preserves (Jauhari and Singh, 1971). In spite of its Indian origin and high medicinal and nutritional values, well organized orcharding of bael is not commonly seen in the country. It is mainly found in wild and semi-wild condition throughout the India. Besides, it is also grown in the homestead gardens, backyards, religious places and farmer’s fields (Misra and Uniyal, 2013).

Impatiens balsamina (Balsam, Garden Balsam or Rose Balsam or Gulmehndi) is a species of Impatiens widely cultivated as an ornamental plant in landscaping belongs to the family Balsaminaceae. It is a qualitative short-day plant, propagated by seed and is one of the popular species of North India. It is called kamantigue in the Philippines. This species of Kamantigue are used in teas. In many English speaking countries they are known as “Touch me not”, possibly due to the ripe seed pods explosively bursting when touched. Different parts of the plant are used to treat disease and skin afflictions such as the leaves, seeds, and stems. It is also edible if cooked. Juice from balsam leaves treats warts and also snakebite, while the flower can be applied to burns to cool the skin. Impatiens balsamina L. has been used as indigenous medicine in Asia for the treatment of rheumatism, fractures, and fingernail inflammation. In Korean folk medicine Impatiens (‘Bong Seon Wha Dae’) has been used to cure constipation and acute gastritis by meat. There are mainly four forms of I. balsamina namely red, purples, white and pink.

ORIGIN AND DISTRIBUTION

Impatiens balsamina is a species of Impatiens native to southern Asia in India and Burma, but has been cultivated widely. It is now naturalized in many tropical and temperate areas of the world. Jones and Smith in 1966 proposed the Himalayan region as the centre of origin. The major centres of diversity are in highlands and mountains of tropical and sub-tropical Africa, Southeast Asia and the Indian sub-continent. In the U.S., Impatiens balsamina is found primarily in a wide strip encompassing the Northeast and Southeast regions from Florida to New York with specimens being found as far west as Missouri. Impatiens denisonii is a scapigerous herb which is found only in the Western Ghats in South India and are endemic in the Nilgiri Hills. Impatiens ecornuta, the spurless touch-me-not or western touch-me-not, is an annual flowering plant native to the northwestern United States and British Columbia in Canada. Impatiens flaccida is native to the Western Ghats in India and to Sri Lanka whereas, Impatiens hawkeri (New Guinea impatiens) is native to Papua New Guinea and the Solomon Islands. It has been bred and hybridized in cultivation to produce a line of garden plants. The species has been crossed with Impatiens aurantiaca and I. platypetala to improve characteristics such as drought-resistance. Impatiens irvingii is native to tropical Africa. Impatiens namchabarwensis (Blue Diamond Impatiens) is a 40–50 cm tall perennial plant, native to the Himalaya overwintering by a thick fleshy rootstock. Impatiens psittacina, known variously as the “parrot flower” or “parrot balsam” is a species of balsam from Southeast Asia that was described by the botanist Joseph Dalton Hooker and was noted for its flower that resemble a “flying cockatoo”. It is known from Thailand, Burma and parts of India (Morgan, 2007). Impatiens sodenii is native to Kenya and Tanzania. It is widely cultivated as an ornamental plant. I. walleriana is native to East Africa and yielded ‘Elfin’ series of cultivars, which was subsequently improved as the Super Elfin series.

ABSTRACT

The paper discusses distribution of bamboo, their uses and bamboo based agroforestry systems in India and their future potential. Bamboo, one of the fastest growing plant species is extremely versatile and has been traditionally put to a large number of uses. Application of modern technology and industrial processing has catapulted bamboo into a new global limelight. At present there is huge demand of bamboo based raw material viz., timber, plywood, bamboo flooring, edible bamboo shoots, etc. in the international market and most of the international market of bamboo is captured by China. In India, most of the bamboo raw material comes from natural forest. To capture the emerging bamboo market we have to increase the bamboo cultivation outside the forest under different bamboo based agroforestry systems. Experiments have shown that bamboo based agrisilviculture systems is technically and economically feasible in our country under different agro-ecological conditions. The agriculture crops which can be profitably grown with bamboo are soybean, pigeon pea, ginger, turmeric, etc. Keeping in view the international scenario, ecological conditions and taking clues from China’s success stories, some of the bamboo based agroforestry system components are also proposed.

ABSTRACT

The paper discusses the problems of soil and water erosion in the Shivalik foot hills and suggests strategies for improved land use planning and the role bamboo species can play in mitigating the problems. The paper also discusses the various bamboo species of the Shivalik foothills, their regeneration, planting practices, management and utilization pattern in detail.

• It is controlled to parthenocarpy and sterility which can be achieved by triploids. Wild species - M. acuminata and M. balbisiana
• The cultivated edible banana is mainly triploid.
• The major problems in the breeding of banana are sterility, polyploidy and parthenocarpy.
• The underground portion of banana is a modified form of stem known as rhizome.
• The portion above the ground made of sheaths of leaves is known as pseudostem.
• Banana initiates flowering 9-12 months after planting.
• Sword sucker with narrow, slender leaf blades is the best planting material.
• Banana is a moisture and nutrient loving shallow-rooted plant.
• Simmonds and Shephard (1955) devised a scoring technique for genomic classification of banana.
• Pollination in banana is mediated mainly by bees and birds.
• Banana fruit follows the double sigmoid growth curve (seeded -sigmoid parthenocarpic - double sigmoid)

Origin and history : Banana is an important fruit of tropics. The fruit is recognized as the fourth most important global food commodity. India’s share is 32 per cent of the total fruit production. This is the only tropical fruit which is exported in large quantities and is leading fruit in the international trade. It is one of the oldest and commonest of the Indian fruit that has been cultivated since ancient times. Eve was said to have used banana leaves to covers her modesty in the garden of paradise. Banana is thus called apple of paradise. It is also known as “Adam’s fig or tree of wisdom”. It is used as staple fruit in most of the African countries and is used as ripe (table) or raw fruit (cooking). This fruit is available throughout the year. All the plant parts are being used. Banana is monocotyledonous plant true stem is rhizome which is a modified form of stem fruit is seedless due to parthenocarpy and the development of fruit is due to auxin stimulation. India has more than 300 germplasms, out of 600 reported worldwide. Edible banana has arisen as a result of natural crosses between two wild progenitors viz,. Musa paradisiaca and Musa balbisiana. Banana is being grown in many of the African countries between 300 N and 500 S latitudes. Important countries are India (1st place).

Statistics involves procedures for collection, classification, analysis, interpretation and presentation of numerical data (Gupta, 1997). Statistical investigations involves four stages ie. collection of data, compilation of data, analysis of data and drawing inferences. For any statistical analysis, first step is data collection which constitutes the foundation for statistical analysis. The required data may be obtained either through survey or an experiment. Survey is the process of collecting data from a population but have no control over the factors which may affect the population characteristics under study, whereas in experiment, data is collected while control is exercised over the factors which may affect the population characteristics under study. Experiments always and almost provide better information than the survey but surveys are necessary in natural populations. When data is not available, it is collected by any of the two methods i.e. census or survey method. In census method, data are collected for each and every unit of the population whereas in sample method a representative sample is drawn from the population on the basis of which all the conclusions are drawn about the population from that sample.

A. Principles of spices breeding
Plant breeding is a science-based technique aimed at improving the genetic makeup of plants to develop desirable traits such as increased yield, resistance to diseases and pests, improved quality, and adaptability to various environmental conditions. When applied to spices, these principles are adapted to meet the unique characteristics and challenges of spice crops.
A.1. Understanding the breeding objectives
• Yield improvement: Increasing the yield of spices like black pepper, ginger, and turmeric is a primary goal. This involves selecting varieties that produce more berries, rhizomes, or seeds.
• Quality enhancement: For spices like vanilla, cinnamon, and saffron, the focus is on enhancing the quality of the product, such as increasing vanillin content, oil content, or curcumin levels.
• Disease and pest resistance: Developing resistant varieties is crucial for spices prone to specific diseases, like black pepper’s vulnerability to foot rot or large cardamom’s susceptibility to fungal diseases.
• Adaptation to environmental conditions: Breeding efforts often aim to produce varieties that can thrive in specific climates, such as the cool, shaded forests required for large cardamom or the arid conditions suitable for cumin.

In general, plants show two distinctive phases; i.e. vegetative growth and reproductive growth. The primary objective of plant species is to reproduce themselves through the reproductive phase. However, some of the plant species do not produce viable seeds, but reproduce themselves in nature by other means. Flowering and fruiting habits vary with plant species and are governed by the kind of plant species and its growth habit, environment etc. In general, flowering and fruiting habits are known as bearing habits and it can be described by the location and type of buds, which produce flowers and fruit. The relative position of fruit with reference to its potential bud-giving rise to flower or inflorescence on the shoot is known as bearing habit. Each plant has its own bearing habit and are either terminally, laterally or adventiously Terminally means the fruit buds are formed on long or short growth, while laterally means the fruit buds are formed in the axils of present or past season’s growth. Adventiously, the fruit buds are formed at any point on the trunk. On the basis of bearing habits, fruit crops are categorised into the following eight groups

Growth, Fruiting Habits and Methods for Inducing Fruitfulness in Fruit Crops

•    Every plant has two distinct phases of development namely vegetative and reproductive.

•    In the vegetative phase, the plant only vegetative growth i.e. leaves, shoots etc.,

•    In the reproductive phases the plant produces reproductive growth i.e. flowers and fruits.

•    In case of annuals, these phases occur for a short period, each phase occurring only once and that too within the same season.

•    In perennials, the vegetative phase lasts for several years depending upon the variety and species. This is known as the pre-bearing period.

•    Once the perennial tree completes its pre-bearing period, the cycle of vegetative and reproductive phases might occur in each season or the reproductive phase may occur simultaneously along with vegetative phase without much distinction between the two.

Begonia is a perennial flowering plant belongs to family Begoniaceae. Begonia has rich colour and beautiful form of flowers. It is free flowering and striking foliage with free growth. The name Begonia is given by Franciscan monk Charles Plumier a plant which he found during his journey from Haiti to island Martinique. He dedicated this plant to “Michel Begon” the man who had the direct manmade over the expeditions. Begonia is easy to propagate and grown from seeds and vegetative means particularly cuttings. It is a popular flowering potted plant grown in containers and hanging baskets including tuberous, semperflorens, Rex, Elatior, Loraine and gracilis. Modern commercially cultivated begonias are mostly hybrids between wild types from all over the world.

ORIGIN AND DISTRIBUTION

Begonias are native to South America and second centre of diversity is Asia from Himalayas to Southern China and Malaysia (a floristic region that encompasses Malaysia, Indonesia, Brunes, Philippines and Paera New Guinea).

The distribution of Begonia diversity is uneven throughout tropical regions, with the greatest diversity in America and Asia (>600 species each), whilst being relatively species poor in Africa (160 species) and absent in Australia (Goodall-Copestake et al., 2010). The genus is thought to have originated in Africa, while South American and South East Asian species are the results of parallel radiations over the last 20-50 million years (Plana et al., 2004, Goodall Copestake et al., 2010 and Thomas et al., 2011). Long distance dispersal is rare, for example Begonia species have failed to cross the Torres Strait from Papua New Guinea to Australia.

Ber (Zizyphus mauritiana Lamk), is an ancient fruit crop of India. It is relished for its sweet and sour fruits. The fruits are nutritious containing high amount of vitamins like C, A and B complex. The genus Zizyphus belongs to the family Rhamnaceae, consisting of 40 species of tropical and subtropical regions of northern hemisphere (Yadav et al., 2005). The one Zizyphus jujube (Chinese jujube) and the other Zizyphus mauritiana (Indian ber) are the two important species grown widely in temperate, tropical and subtropical regions of the world. The ruggosa and nummalaria are other important species.

PRESENT STATUS

Ber, a popular fruit, is being grown as almost commercially important fruit crop. It has better adaptability in marginal soils in arid region of subtropics. It is mainly grown in India as well as different countries in central Asia, China and Taiwan. It has been truly called as poor man‘s fruit/poor man‘s apple. Ber can suitably be grown almost in all the parts of north Indian plains in Uttar Pradesh, Haryana, Punjab and Rajasthan. Seedling ber trees are found extensively growing widely in arid and semi arid areas.

Origin and history : Ber is an ancient fruit crop of India and is relished for its sweet and sour fruits. It is an ideal fruit tree for arid and semi arid regions in tropical and subtropical climate. It is highly suitable for marginal land and hot arid region. It is distributed in tropical and sub tropical country in the world, including China, Pakistan, Australia and France. In India the major growing states are Madhya Pradesh, Bihar, Uttar Pradesh, Punjab, Haryana, Rajasthan, Gujarat, Maharashtra, Andhra Pradesh etc. In Uttar Pradesh, Varanasi, Aligarh, Ayodhya, and Agra are the major growing region. Beside mauritiana other important species like Zizyphus rotundifolia, Zizyphus numuleria, Zizyphus rugosa, Zizyphus xylopyrus, Zizyphus micropyla is also commercially grown for rootstock purpose.

ABSTRACT

Fodder availability is a serious concern during winter season in hilly areas as land for growing fodder crops is hardly available unlike plains. Bhimal as an agroforestry species is being cultivated in the Himalayas since long, however, genetic improvement of the species was hardly undertaken in the past barring a few reports on tree improvement of the species. Seeds were used to be usually collected from crooked trees which are easy to climb or swept from the forest floor. Since agroforestry systems have great promise to improve the productivity of both agricultural and tree crops, therefore, keeping that in view, seven provenances (I.C. Bhaintan , I.C. Chamba, I.C. Katkor, I.C. Malas, I.C. Nauni, I.C. Naur, I.C. Tachla) were collected from different regions of Uttarakhand and Himachal Pradesh and evaluated for 10 years (1995-2004). Significant differences in the productivity potential of Bhimal provenances were noticed and the high yielding fodder provenances identified (I.C. Bhaintan , I.C. Chamba and I.C. Malas), yielding as high as 35 q ha^-1 thus fodder productivity could be increased to 25% by planting high yielding provenances. Likewise high yielding provenaces (HYPs) for fuelwood and fibre were identified which can increase the productivity potential of the agroforestry system. In 2005, more than 1200 saplings of HYPs were multiplied in a polyhouse and planted at different elevations in the Himalayas under prevailing agroforestry systems. Differential responses of HYPs in respect of growth and productivity at different locations have been monitored. The rooting behaviour of HYPs was also investigated and it was found that all the three provenances viz., I.C. Bhaintan, I.C. Chamba and I.C. Malas have high soil binding characteristics, thus revealing that apart from production, this tree species plays an important role in soil conservation. Further, high regression of soil binding on above ground biomass and specific root length was recorded among these provenaces. Looking at the performance of such provenances on the farmers’ fields, the demand of high yielding provenaces is increasing. Unlike Eucalyptus, Bhimal had the minimal effect on the performance of field crops and the overall system productivity of the Grewia optiva based agroforestry system was profitable along with insurance against aberrant monsoon conditions.

Anacardium occidentale is a medium-sized tree, spreading, and evergreen, much branched; grows to a height of 12 m. When grown on lateritic, gravelly, coastal sandy areas, it rarely exceeds 6 m and develops a spreading habit and globose shape with crown diameter to 12 m but, if grown inland on loams; it reaches 15 m tall and is much branched, with a smaller (4-6 m) crown diameter. The root system of a mature A. occidentale, when grown from the seed, consists of a very prominent taproot and a well developed and extensive network of lateral and sinker roots. Leaves simple, alternate, coriaceous, glabrous, obovate, rounded at ends, 10-18 x 8-15 cm, with short petiole, pale green or reddish when young and dark green at mature. Rai and Vatsala (1985) studied the dermal morphology and stomatal ontogeny of Spondias pinnata Kurz., Lannea coromandelica (Houtt.) Merr., Anacardium occidentale L., Holigarna arnottiana Hook. F. and Mangifera indica L. are studied. The cuticle is thick in H. arnottiana, A. occidentale and M. indica, but is thin in S. pinnata and L. coromandelica. Based on the shape of epidermal cells, the five species are categorised into three: cells in both upper and lower epidermis sinuous (A. occidentale, H. arnottiana, S. pinnata); upper sinuous and lower polygonal (M. indica) and upper polygonal and lower sinuous (L. coromandelica). Stomatal ontogeny aperigenous (L. coromandelica), paramesoperigenous (A. occidentale) and anisomesogenous (M. indica, H. arnottiana). S. pinnata is peculiar in that it possesses three different types of stomata, aperigenous, hemiparamesoperigenous and paramesoperigenous; whereas, in all the other four species, only one type of stomatal ontogenesis exists. Except S. pinnata, all the other species possess epidermal appendages. Unicellular trichomes occur in A. occidentale and H. arnottiana, and multicellular glandular trichomes in A. occidentale, M. indica and L. coromandelica. The multicellular hairs are found in A. occidentale in specialized pockets in two rows on either side of the major veins - a unique feature which is reported for the first time.

INTRODUCTION

Biodiversity  refers to varieties of life on the Earth including  animals, plants, microbes and genes within them, their habitats and ecosystems and all variations within a given ecosystem, biome or entire planet. Biodiversity is the basis of life on Earth, important for the functioning of ecosystems, provides us with products and services without which we cannot live. Consider our food range in India. It ranges from Indian bread (chapatti), rice and rice products and related curries and other varieties made out of different vegetables. These food items are made of wheat, paddy, maize, bajra, ragi, potato, tapioca, sweet potato,  yams and corns, pulses like pigeon pea, green and black gram, Bengal gram, soyabean, vegetables like tomato, brinjal, cucumber, pumpkin, drum stick, bitter gourd, snake gourd, bottle gourd and various gourds, French bean, amaranth and  so many leafy  vegetables, spices and condiments like chilly, cardamom, ginger, turmeric, pepper, nutmeg, clove, cinnamon, cumin, coriander, fenugreek etc. This is the diversity of food we have in India. Similarly, all other groups such as herbal medicine, ornamentals, timber and non-timber species are also very diverse.
