Abstract

Screening for early drought tolerance by using three treatments of PEG-6000, control (T1), 15% (T2 ) and 25% (T3) was employed in six wheat genotypes (DH 114, DH 40, DH 65, C 306, DH 52 and DH 5). The genotypes were 3 evaluated for shoot length, coleoptile length, root length and root to shoot ratio. From the results, shoot, coleoptile and root length decreased with increased PEG concentrations. DH 40 expressed highest shoot length in T and T with least reduction and C 306 witnessed longer coleoptile with least reduction over control. DH 114 2 3 expressed highest root length in all treatments, while DH 40 had least reduction (3.31 and 7.96% in T2 and T3, respectively). C 306 in T3 and DH 114 in T2 were superior for root to shoot ratio. DH 40, DH 114 and C 306 3 2 possessed early drought tolerance behaviour and might be productive in wheat improvement programmes.
