Abstract
The maize hybrid possessing high grain yield and stability to various environmental is required in maize breeding. Eleven yellow hybrids beside two checks were evaluated in a randomized complete block design (RCBD) with four replications at five locations in Egypt i.e. Sakha, Gemmeiza, Sids, Mallawi and Nubaria in 2022 season to identify, the superior hybrids for both high grain yield and stable under multi-locations.The mean squares of locations, hybrids and their interaction were highly significant for most studied traits. The best hybrids were SC Sk166 for earliness, plant and ear heights and SC Sk157, SC Sk158, SC Sk162 and SC Sd155 for high grain yield compared to commercial hybrids, SC168 and SC162. The two hybrids SC Sk162 and SC Sd155 were more stable in most stability measures used.So,this study recommended using hybrids, SC Sk162 and SC Sd155 in Egyptian breeding program for high grain yield and stable. The correlation between two parameters (CV% and bi), (CV% and S2di), (CV% and Si (2)), (bi and R2), (Wi2 and Si (1)), (Wi2 and Si (2)) and (Si (1) and Si (2)) were positive and significant, indicating that both two parameters were similar in selection stability hybrids, hence only one from the two parameters would be sufficient to select stable hybrid. Meanwhile, the correlation between two parameters; (R2 and Wi2 ) and (R2 and Pi) were negative and significant, consequently the two parameters were differ in estimation stability of hybrids, so the two parameters should be used independently to estimate stability of hybrids.
