Abstract:
The present investigation carried out by the assess the heterosis for grain yield and its contributing characters under three different environmental conditions using eight diverse barley parents along with their 28 F1. Heterosis for grain yield per plant range from -11.48 per cent to 18.93 per cent in E1, -8.38 per cent to 14.91 per cent in E2 and -18.13 per cent to 18.5 per cent in E3. Seven crosses in E1, eleven crosses in E2 and E3 each exhibited positive significant heterosis while four crosses in E1, six crosses in E2 and nine in E3 exhibited positive significant heterobeltiosis. The crosses BH902 × RD2904, BH902 × DWR143 (except E1 both heterosis and HB), RD2904 × RD2909 (except E1 and E2 in HB), and DWR143 × DWR137 (except HB in E1 and E2) in all the environments exhibited positive significant heterosis. Hence, these crosses were considered to be most desirable for grain yield per plant. The heterosis over better parent varied from -15.92 (RD2909 x HUB242) to 11.54 (BH902 x DWR143) in E1, -12.83 (UPB1059 x DWR137) to 10.43 (BH902 x RD2904) in E2 and -21.13 (RD2909 x BH959) to 17.97 (HUB242 x BH959) in E3, respectively. For heterotic effects of grain yield, four hybrids in E1, six hybrids in E2, nine hybrids in E3 and four crosses in pooled analysis gave high amount of heterotic effects.
