| Abstract | ||||
| Increasing maize production in Egypt is one of the most important goals of the breeding program of the Maize Research Department. Registration and releasing of superior new hybrids for grain yield is one of the most important factors to achieve this goal. This study included four promising white maize single crosses; SC-Sk138, SC-Sk148, SC-Sk153 and SC-Sk154, one promising yellow single cross SC-Sk150 and one promising red single cross SC-Sk1. These six new hybrids were evaluated in several stages according to the Egyptian hybrid registration program which includes two tests; value for cultivation and use (VCU) and distinction, uniformity and stability (DUS). Six new hybrids were succeeded from all the Egyptian hybrid registration rules during the period from 2019 to 2024 summer season. So, these hybrids were registered as new commercial hybrids. The white hybrid SC-Sk138 was commercially named SC133, the yellow hybrid SC-Sk150 was commercially named SC187 and the red hybrid SC-Sk1 was commercially named SC190. These three hybrids had high performance and broad adaptability for grain yield. Therefore, this study recommended to planting them in various regions in Egypt. Meanwhile the white hybrids SC-Sk148, SC-Sk153 and SC-Sk154 were commercially named SC134, SC135 and SC136, respectively; these three hybrids had high performance and were well adapted to specific environments for grain yield. Therefore, this study recommends planting them in Middle and Upper Egypt. | ||||
