Use of Physiological Parameters for Screening Drought Tolerant Barley Genotypes
With the aim of understanding and identifying the traits which can be used as the suitable criteria for quick screening of the water deficit tolerant barley genotypes, an experiment based on randomized complete blocks design with three replications was conducted during two years to evaluate the biochemical responses of 20 barley genotypes to full irrigation and terminal water stress in the fie...
متن کاملscreening for drought stress tolerance in cowpea genotypes )vigna unguiculata l (.
introduction drought stress is one of the most important abiotic stresses all around the world. the aim of breeding studies and breeding for resistance to drought is that breeders seek to identify varieties and genetic resources to drought resistant and comparison of drought resistance among the varieties and the introduction of superior varieties to farmers. drought or imbalance between supply...
متن کاملscreening for terminal drought stress tolerance in cowpea genotypes (vigna unguiculata l.)
in order to study and determine the most effective traits, drought tolerance indices and identify tolerant genotypes in terminal drought stress on the cowpea, an experiment was carried out based on an augment design in two separate conditions in the karaj farm, faculty of agriculture, tehran university in 2009. drought stress was imposed by cutting irrigation after flowering against normal irri...
متن کاملSelection of Novel Cowpea Genotypes Derived through Gamma Irradiation
Cowpea (Vigna unguiculata [L.] Walp.) yields are considerably low in Namibia due to lack of improved varieties and biotic and abiotic stresses, notably, recurrent drought. Thus, genetic improvement in cowpea aims to develop cultivars with improved grain yield and tolerance to abiotic and biotic stress factors. The objective of this study was to identify agronomically desirable cowpea genotypes ...
متن کاملgenotypic x environmental interaction of cowpea genotypes
twenty four cowpea varieties were raised at niab and arri, faisalabad selected for plant height (42-136cm) days taken to 95 % flowering (62-79 days) and for diseases resistance (0.67-7 rating). infestation was maximum on it-97k-461-4, 1068-7, it-97k 1042-8 and it-98k-558-1 and was graded as susceptible. maximum grain yield was recorded in elite (649 kg/ha) and lowest grain yield was observed in...
