Track 4-1-2: Breeding Cultivated Forage Species for Biomass, Quality and Stress Tolerance
Description
Oats is the most important cereal fodder crop grown in the winter season in the north western, central India and now extending to the eastern region. In India it is grown in Punjab, Haryana, Jammu & Kashmir, Himachal Pradesh, Uttar Pradesh, Madhya Pradesh, Rajasthan, Maharashtra and Bengal. Oat is a high yielding crop and the average yield varies from 45-55 ton of green fodder per hectare. Oat is ranked sixth in world cereal production statistics following wheat, maize, rice, barley and sorghum. Mostly oats are grown as green fodder and grain to be used as a feed for cattle. Since water availability is usually main factor affecting the productivity in dry regions, strategies aiming at improving sustainable use of water and plant drought tolerance are urgent (Erice et al., 2010). The physiological and morphological responses of cereals to water stress have been studied extensively by Boyer and Westgate (2004) and Blum (2005). Genetic modification of plants by breeding and identification of germplasm for their growth and yield under unfavorable conditions may be a solution to the problem of environmental stresses. The present work aims to study the morphological, physiological and biochemical changes in seven Avena species grown under water limited environment. The study also aims to identify some drought tolerant species for its utilization as the donor in oat breeding programme.
