Abstract:
A field experiment was conducted at the Dr. P. D. K. V., Akola, during Rabi 2018-19 seasons, to study yield and its components of full diallel wheat bread crosses. A Randomize Block Design (RBD) with three replications was used for the experiment. The experimental material comprised of 145 genotypes including 132 F₂ crosses (Direct and reciprocal crosses), 12 parents and one check (WB-2). Analyses of Variance for all the treatment showed highly significant differences for nine characters indicated the presence of extensive amount of genetic variability. The result of residual heterosis over check for grain yield per plant revealed that the cross combinations WB-2 x GW-322, MACS-6222 x WB-2, HPBW-01 x WB-2, MACS-6222 x HPBW-01, MACS-6222 x GW-322 direct crosses and GW-322 x WB-2, GW-322 x AKAW-4925, GW-322 x K-307 reciprocal crosses were good along with the combined range of -47.37 (AKAW-5017 x HPBW-01) to 57.89% (WB-2 x GW-322). The above crosses were seen to perform stably for all the characters studied. Hence can be exploited for further wheat breeding programs.
