Bidens pilosa L., a less-known cultivated tea species was collected from cold desert of Ladakh Himalaya, Jammu and Kashmir, India during 2004. The freshly harvested leaves are used in preparation of ‘Ladakhi tea’ locally known as ‘Saja’ or ‘Soljaa’ in cold desert of Ladakh Himalaya, Western Himalaya, Jammu and Kashmir. The local inhabitants were growing this species in their kitchen garden for this use. In the present communication, the method of preparation of this beverage is also discussed.  相似文献

Chinese chives (Allium tuberosum Rottler ex Sprengel) is a less known cultivated vegetable in western and eastern Himalayan regions of India. This species is reported here for its potential for commercialization to supplement the onion and garlic production in different parts of India especially under the present unpredictable climatic conditions. Due to multipurpose use and wider adaptability of the species future thrust is laid on collection and conservation programmes in India.  相似文献

A total of 373 species of wild relatives of crop plants representing 120 genera and 48 families were collected from different phytogeographical regions of India during a mission mode sub-project on Sustainable Management of Plant Biodiversity under National Agricultural Technology Project during 1999–2005. Significant diversity representing endemic/rare/endangered species has been discussed in this paper. The information on phytogeographical distribution, life form, economic types and assessment of threat has also been included. Thrust areas for future target collections and conservation have been discussed to serve as reference for management of genetic resources.  相似文献

Perilla frutescens (L.) Britton is a traditional crop of East Asia and sporadically cultivated in different parts of the Himalayas. The Western and the Eastern Himalayan regions of India exhibit rich variability in oilseed Perilla, Perilla frutescens (L.) Britton var. frutescens. The present communication deals with the distribution pattern of diversity and survey, exploration and germplasm collection and its uses in India. Brief information on botanical characterization on the basis of systematic study of cultivated and weedy types and thrust on areas for germplasm collection from diverse habitats have been discussed.  相似文献

Assessment of diversity in cultivated and wild useful Crotalaria L. distributed in different phytogeographical regions of India was made. Sites of germplasm collection were depicted on maps to facilitate planning and execution of collection and conservation programmes. In the present communication, information on useful and potential species of Crotalaria in India has also been documented for widening their scope in plant genetic resources management.  相似文献

An aquatic cash crop, ‘makhana’ (Euryale ferox Salisb.) was studied for predicted habitat suitability through ‘BioClim’ model for the year 1950–2000 and projected climate data for 2050 and 2070 for the Indian region based on primary data from survey and exploration for germplasm collection by ICAR-National Bureau of Plant Genetic Resources (ICAR-NBPGR), New Delhi, India. A total of 362 diverse ‘makhana’ or foxnut germplasm accessions were augmented mainly from different districts of Indian state of Bihar and conserved at the National Genebank (NGB) at ICAR-NBPGR, New Delhi. Predicted habitat suitability map of climate for the period 1950–2000 showed that the current locations of the highly suitable areas of cultivation of ‘makhana’ in Bihar were extended to other states namely- Jharkhand, Uttar Pradesh and West Bengal in eastern India. Out of the total highly suitable estimated areas, maximum were located in Bihar (65.0 per cent) followed by Uttar Pradesh (12.3 per cent), Jharkhand (12.2 per cent) and West Bengal (10.5 per cent). Based on future predicted climate data for the year 2050 the habitat suitability map indicated that out of the total high suitable areas, Bihar had maximum area as compared to the other three states. Predicted climate data using ‘BioClim’ variables showed that high suitable areas shifted from major part in Jharkhand, Uttar Pradesh and West Bengal and negligible areas bordering Katihar district of Bihar. While predicted climate data for the year 2050 and 2070 showed high suitable areas in West Bengal, especially Malda and Dakschin Dinajpur districts completely shrank due to temperature rise; while Uttar Dinajpur (Goal Pokhar-I, Goal Pokhar-II and Islampur districts) appeared as new areas. In Uttar Pradesh, new districts viz. Balrampur and Shravasti were identified as high suitable areas for ‘makhana’ cultivation. As ‘makhana’ is a popular cash crop of eastern part of the country, and has not been cultivated widely in other regions, hence the knowledge on its botany, distribution, cultivation practices and uses are provided.

The genetic diversity in genus Prunus is mainly confined to temperate regions of Himalaya and to a lesser extent in the sub-montane and hilly regions of peninsular India. The cultivated and wild species of Prunus have tremendous potential for improvement and utilization. This paper includes the genetic resources of cultivated and wild useful species of Prunus in India with emphasis on their distribution, potential traits/ useful characteristics and utilization. The information on potential genetic resources of Prunus would be helpful in collection, evaluation, conservation and utilization of species.  相似文献
