| Abstract | ||||
| stable assortment is fundamental for long-haul grain yield security to the ranchers. Creating site-explicit assortment is a decent approach to keeping up with variety and getting possible yield. Stable boundaries were assessed given twelve rice assortments assessed under three different planting dates at research homestead of Sakha research station KafreElshiekh Egypt, during 2021 and 2022 seasons. The genotypes were affected by the shifting circumstances and G x E connection which was profoundly critical for a long time to development, seed set % and collect record, showing to responses of the rice assortments in various conditions. These characteristics are vital for adoption of assortments in rancher's field. It very well may be construed that, itis plausible of creating nearby unambiguous assortment which is steady and adaptable across these conditions. From the results showed that, the rice Sakha 106, Sakha107, Sakha 108 and Giza 178 are near 1 regarding bi indicating that, these cultivars are adapted under different environments. While, Values of less than one for bi indicated that the cultivars Giza 177, E. yasmin, and Sakha super 300 were appropriate for unfavorable conditions. Conversely, Sakha 101, Sakha 104, Sakha 105, and Giza 182 demonstrated bi values greater than 1, indicating their suitability for good conditions and their poor performance in unfavorable ones. Because of this, these rice cultivars can be useful for studying harsh environments. The discovered types are suggested because they are suitable for harsh situations. | ||||
