3.1.2. Relative Water Content (RWC)
The relative water content in all the studied genotypes showed significant difference in both control and drought stress condition. The mean value under normal condition 100% field capacity 94.580% was recorded while in drought stress condition 80% field capacity the mean value for relative water content 81.887% was recorded for all the studied genotypes. In drought stress 60% field capacity the mean value for relative water content 73.659% was recorded (Table 1, Fig. 2). In general, RWCs declined during water stress in all the studied wheat genotypes. The Analysis of variance (ANOVA) result showed that in drought condition the interaction between genotypes and different levels of drought stress are not positively significant (Table 2). The least significant difference (LSD) indicated that in 100% field capacity the relative water content were not affected and maximum relative water content 96.477% were recorded for SD-32 genotype followed by chirya-1 genotype. Similarly in drought stress 80% and 60% field capacity the maximum relative water content was recorded for chirya-1 genotype which was 82.8% and 76% respectively (Table 3)
