EVALUATION OF SORGHUM GENOTYPES FOR CERTAIN PHYSIOLOGICAL CHARACTERS WITH YIELD AND INTERRELATIONSHIP ANALYSIS UNDER WATER STRESS CONDITION

Abstract

A total number of 21 sorghum varieties was screened for stress resistance at the vegetative stage of the crop. The grain yield was less affected compared to nonstress. The cultivars viz., SPV 393, KS 7193, KS 6312 and TWC 120 were found to be drought tolerant after evaluating for most of the physiological characters and yield. The intercorrelation of ten characters showed that grain yield showed significantly positive correlation for number of closed stomata both in stress and nonstress condition. Highest non significant correlation was noticed for grain yield and leaf wilting/rolling. DMP/plant and stomata count under stress.
