Evaluation of Germplasm Accessions for Drought Tolerance in Green Gram [Vigna Radiata (L.)]

Abstract
An experiment was conducted to screen 200 germplasm accessions of green gram for drought tolerance using augmented design during summer 2015 under drought stress condition. ANOVA revealed high significant differences among germplasm accessions for yield, yield component traits and also for drought tolerance traits.Mean squares attributable to ‘Genotypes vs check entries’ were significant for all the traits except seeds per podand relative water content. Genotypic coefficient of variation and phenotypic coefficient of variation were found to be on higher side for grain yield, yield components such as clusters per plant, pods per cluster and pods per plant. Higher values of GCV and PCV were also observed for drought tolerance traits such as chlorophyll content (spad chlorophyll meter reading), leaf water potential, proline content, relative water content and specific leaf area. The grain yield, yield component traits and drought tolerance traits exhibited high heritability (broad sense) coupled with high to moderate expected GAM.
