SUMMARY
Heterosis analysis was carried out in 28 F1 hybrids and their 8 diverse parents for fodder yield, its quality and other yield related traits during Kharif 2016-17 at Sorghum Research Station, Sardarkrushinagar Dantiwada Agricultural University, Deesa. Analysis of variance revealed significant differences among the genotypes, parents and hybrids for all the traits. Several crosses exhibited significantly desirable heterobeltiosis and economic heterosis for green fodder yield plant-1 and other characters. On the basis of per se performance and estimates of heterosis, the crosses DSF 127 X CSV 15, CSV 21 F X MP Chari, DSF 117 X DSF 123, CSV 15 X GFS 4, DSF 123 X GFS 4 and CSV 21 F X GFS 4 were found most promising for green fodder yield per plant.
Key words: Heterosis, Forage sorghum, Fodder yield
