Abstract:
For the present experiment assessed the magnitude of heterosis by using 9 parents were crossed in diallel (without reciprocals) mating design to obtain 36 crosses during rabi 2017-18. The experimental material thus consisted of 9 Parents 36 crosses and 2 checks viz., RD 2899 and BH 946, total of 47 entries, were evaluated during rabi 2018-19 in Randomized Block Design (RBD) with 3 replications, the observations were recorded for 13 characters to study the magnitude of relative heterosis (RH), heterobeltiosis (HB), economic heterosis (EH). One cross RD 2786 × BH 959 depicted positive significant economic heterosis (8.82%) for grain yield per plant over the best check BH 946 and also exhibited positive economic heterosis for flag leaf area, spike length, 1000-grain weight. Heterobeltiosis for grain yield per plant was exhibited by cross RD 2035 × DWRB 92 and maximum relative heterosis exhibited by the cross DWRB 91 × BH 959. Parents RD 2786, RD 2715 and BH 959 could be recommended for utilizing in varietal development.
