| Abstract | ||||
| Twenty crosses of grain sorghum, their parents (five CMS and four restorer lines) and one commercial check hybrid (H-305) were evaluated in a randomized complete blocks design for yield and three other traits in 2022 and 2023 seasons at Arab El-Awamer Station, Assiut, Egypt under normal and salt affected soil conditions. The genetic parameters were estimated using line x tester analysis. Combined analysis across two seasons showed, highly significant differences among genotypes for all studied traits under normal and salt-affected soil conditions. The mean squares of females, males and females x males were highly significant for all studied traits under normal and salt-affected soil conditions except 1000-grain weight for males under salt-affected soil, A-line ICSA-88004, ICSA-37 and the restorer line ICSR-93002 had positive and significant general combining ability effect for grain yield under the normal and salt-affected soil across two years the four crosses (ICSA-88004 x ICSR-92003), (ICSA-88004 x ICSR-93002), (ICSA-91003 x ICSR-89022) and (ICSA-37 x ICSR-89010) had positive and significant specific combining ability effects and higher superiority relative to the check (SH-305) for grain yield/plant under normal and salt-affected soil across over two seasons. These crosses will be tested in large scale for grain yield. | ||||
