Abstract

A total of 203 genotypes of grain sorghum including 8 lines and 21 testers and their 168 hybrids with 6 checks were evaluated for grain mold resistance, grain yield and its components in 2 locations in 2 years. Significant genotype and environmental interactions for Panicle Grain Mold Rate (PGMR), Threshed Grain Mold Rate (TGMR) and days to 50% flowering indicating differential behavior of genotypes under different environments for these characters. The hybrids are classified into 3 groups based on stability performance. Forty-six hybrids exhibited stable performance across environments in which top 5 hybrids (ICSA 384 × GD 65028, ICSA 370 × GD 65028, ICSA 384 × GD 65055, ICSA 369 × GD 65028 and ICSA 370 × GD 65055) with low PGMR scores. None of the resistant hybrids were adaptable to favorable environments. Two hybrids, ICSA 369 × GD 65055 and ICSA 369 × ICSR 89058, were suitable for unfavorable environments with low PGMR scores.
