Genetic resources of rice in the Western Himalayan region of India: current status.

摘要: The Western Himalayan region of India possesses rich genetic diversity rice (Oryza sativa L.). Rice landraces having withstood the rigors biotic and abiotic stresses, suit to local conditions farms reflect socio-cultural preferences can still be found in crop fields located distantly rural tribal areas. This is known for growing World fame basmati foot hills many varieties red rices grown at higher elevations, cold tolerance medicinal properties. Genetic resources were collected about 8 years (1999-2006) 1069 germplasm accessions including 154 named collected. Prominent such as Begumi, Ramjwain, Thapachini, Naurang, Hansraj, Tilakchandan, Lalsati, Jhini, Mushakbudji, Jattoo, Barpasso, Qadirbeigh, Safedbrez, Shahie their special quality attributes change land use, cropping patterns aggressive introduction modern has resulted loss a large number especially from irrigated lands. present paper looks status resources, variability, erosion future strategies conserve on farm maximize its use breeding.
