ABSTRACT

To understand the genetics of drought tolerance, two promising elite lines V-04189 and V-03138 were crossed to develop F1, F2 and back cross generations (BC1 and BC2). Six generations (P1, P2, F1, F2, BC1 and BC2) were raised with no recommended irrigations. Analysis of variance showed presence of sufficient genetic variability among six generations. Hybrid vigor was observed in most of the cases except flag leaf area. Generation means analysis revealed two parameter model [md] provided the best fit for relative water contents and excised leaf water loss which shows the presence of additive genetic effect is prominent with simple inheritance The remaining traits exhibited higher parameter models and indicating complex inheritance. Generation means analysis indicating the presence of additive genetic affects that can be fixed in early segregating generations.
