Genotype x environment interactions for grain yield in forage sorghum

Gellotype environment interactions are of considerable importance to the plant breeders as they impose severe restrictions in realizing the expected genetic gain in a breeding programme. In forage sorghum, limited studies have been reported on stability aspects with respect to fodder yield (Dangi and Paroda, 1978; Sharma, 1979), while they are almost lacking for seed yield. However, the stability of grain yield is as important as fodder yield. Accordingly, an attempt has been made to study the genotype x environment interactions for grain yield in multicut forage sorghum
