Morpho-Physiological Characterization Related to Drought Tolerance of Common Bean (Phaseolus Vulgaris L.) Genotypes
Drought is one of the limiting factor in common bean, development of common bean varieties that adapted to drought situations is the main focus for improving food crops. In this study, 25 genotypes of common beans (Phaseolus vulgaris L.) were grown under drought stress and non-stress conditions. The field work was conducted at Melkassa Agricultural Research Center during the off-season that lai...

متن کاملAbortive Seed Development in Common Bean (phaseolus Vulgaris L.)
INTRODUCTION Embryo defective mutants in Phaseolus vulgaris obtained by Ethyl methanesulfonate (EMS) induction were studied to determine the structural and molecular basis of seed abortion in this species. In the wild-type, the classical pattern of seed development showed coordinated differentiation of the embryo proper, suspensor, endosperm tissue, and seed coat. On the contrarily, EMS mutant ...
متن کاملDifferences in antioxidant, morphological and biochemical responses to drought stress in different cultivars of common bean (Phaseolus vulgaris L.)
Drought stress is the most common environmental stress that can significantly influence crop productivity. In this study, morphological and biochemical properties of 17 genotypes of common bean were evaluated under different levels of drought stress and the most sensitive and tolerant genotypes were identified using multivariate analysis. The results indicated that morphological and biochemical...
