Estimation of Genetic Parameters of Yield and Yield Traits in Wheat Genotypes under Rainfed Conditions
Development of superior crop varieties is the prime objectives of all plant breeding programs. To determine genetic variability, heritability and genetic advance, 24 elite bread wheat lines were planted in randomized complete block design with three replications at the University of Agriculture, Peshawar under rainfed conditions. Data were recorded on days to heading, days to maturity, plant he...
متن کاملDrought Frontiers in Rice: Crop Improvement for Increased Rainfed Production
The success of the Green Revolution in closing the gap between world population and food production was principally achieved by increasing crop productivity in favorable areas. However, this success has been limited in the rainfed systems, which are prone to frequent droughts and other abiotic stresses. Worldwide, drought affects approximately 23 million hectares of rainfed rice. Varieties comb...
متن کاملParticipatory varietal selection of chickpea in rainfed rice fallow lands of Chhattisgarh and Madhya Pradesh in India for sustainable crop production
Production and area of chickpea are reducing every year in India due tocompetition with horticulture and other cash crops in irrigated areas. There is a greatscope for expanding chickpea production with or without limited irrigation in rainfedrice fallow lands (RRFL) in the states of Chhattisgarh and Madhya Pradesh. Nineteenchickpea genotypes were tested using participatory varietal selection (...
متن کاملBreeding drought tolerant rice for shallow rainfed ecosystem of eastern India
In shallow rainfed rice agro-ecosystems, drought stress can occur at any growth stage and can cause a significant yield reduction. During recent years, some rice varieties possessing tolerance of reproductive-stage drought stress have recently been developed. Tolerance of vegetative-stage drought stress is also required to improve rice productivity in drought-prone regions. In this study, we ev...
