Abstract

Seventy seven sorghum entries comprising 60 hybrids and 17 parents of sorghum (Sorghum bicolor L.) were evaluated for stability for panicle length,number of rachis per panicle, 100 grain weight and grain yield per plant. The hybrids viz., 56 A X TNS 81,205 AX TNS 81 and 205 A X MR 750 were identified as stable hybrids with high yield and per se performance. For adaptable breeding programme for target environment, the hybrids would be of appropriate source materials.
