Abstract:
In present study crosses among the 11 genotypes (eight lines and three testers) were made in a line × tester fashion. The experimental material consisted of 11 parents and their resulting 24 F1’s and check RD 2552, which were grown in a randomized block design with three replications under normal conditions during rabi 2020-21 at the Department of Seed Technology, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar. Heterosis was found in all crosses for all measured barley traits. A wide range of variations in heterosis over a better parent and standard check was observed. For grain yield, the maximum percentage of heterosis over the standard check was observed when crossing UPB 1077 × DWRB 137. The cross UPB 1077 × DWRB 137 showed significant positive heterosis compared with the better parent, followed by DWRB203 × DWRB137. For the character number of grain per spike top auspicious crosses exhibiting the heterobeltiosis in order of merit were UPB 1077 × RD 2786, DWRB 203 × RD 2786 and DWRB 203 × BH 946, and for the economic heterosis top spectacular cross were UPB 1077 × RD 2786, DWRB 203 × RD 2786 and DWRB 203 × BH 946.
