SUMMARY

The present investigation in forage sorghum [Sorghum bicolor (L.) Moench] was carried out to study per se performance and magnitude of heterosis in 27 F1 hybrids with nine female and three male were examined in Randomized Block Design (RBD) with three replications for fodder yield, its quality and other yield related traits during Kharif 2016-17. Analysis of variance revealed that significant differences was observed among the parents for all the characters except plant height. This indicated the presence of adequate amount of variability in parents (lines and testers) for most of the traits under study. An examination of mean performance of parents and hybrids indicated that the female DSF-140, male Malwan and the hybrids DSF-138 × CSV 21 F, DSF-123 × Malwan and DSF-140 × GFS 5 exhibited higher mean performance for green fodder yield per plant and some of the yield contributing traits. The cross combinations, DSF-130 × CSV 21 F, DSF-146 × GFS 5 and DSF-146 × CSV 21 F exhibited significant and positive heterobeltiosis for green fodder yield and its component traits. In case of standatd heterosis over best check CSH 13, the top ranking hybrids viz., DSF-138 × CSV 21 F, DSF-123 × Malwan and DSF-140 × GFS 5 were found promising for green fodder yield per plant and its component traits.
