| Abstract | ||||
| Six white promising single crosses and two commercial hybrids were evaluated under five locations for grain yield in 2021 season. The mean squares due to hybrids, locations, hybrids x locations interaction, linear and nonlinear components were highly significant for grain yield. The hybrids SC Sk 153, SC Sk 154 and SC Sd 18 were significant out-yielded two commercial hybrids, thus these hybrids have high adaptability. However the hybrid SC Sk 154 had high adaptability and stability (bi =1 and S2di not significant) for grain yield. So the study prefers this hybrid. | ||||
