Abstract
Ten sorghum genotypes (Sorghum bicolor L. Moench) were evaluated at three locations namely; Arab El-Awamer, Shandweel, and El-Fayoum Agric. Res. Stations in 2018 and 2019 growing seasons. Planting time at the three locations during the two years were during the 1st week of July. The objectives of this study were to determine the performance and stability of ten sorghum across different locations of Egypt. The study was conducted using a randomized complete block design with four replications. Stability analysis for grain yield, 1000-grain weigh, plant height and days to 50% flowering were estimated using Tai’s statistical method. A combined analysis of variance emphasized the significant effect of genotypes and locations for all studied traits. There was nonsignificant effect of year for all studied traits, except for 1000-grain weight. The effect of location on Sorghum grain yield and the other studied traits was greater than the effect of year. Hence, testing genotypes under many locations should be done rather than years. Significant effect of genotype x location interaction, suggesting that each genotype differentially responded to the change in the investigated locations. Based on Tai’s stability analysis, 3 out of 10 tested sorghum genotypes i.e., (ASH-8 x ICSR-93002), (ASH-9 x ICSR-93002), and (ASH-12 x ICSR-93002) showed average stability and gave high yielding compared to the general mean and are thus the most stable grain sorghum genotypes for grain yield. Generally, Tai’s stability method was facilitated the visual comparison and identification of superior genotypes, thereby supporting decisions grain sorghum genotypes for different environments.
