Abstract : The present investigation consists of 28 genotypes of wheat, which were procured from Wheat Breeding Programme, Directorate of Research, Sam Higginbottom Institute of Agriculture, Technology and Sciences, (Deemed to be University), Allahabad, UP, India. The experiment was conducted during Rabi 2008-10 in RBD having three replications. The data were recorded on twelve characters to study the variability, heterosis and contribution of plasma gene determining the heterosis. The significant mean sum of squares for all the 12 characters indicated the presence of substantial amount of variability. Per se performance for grain yield and its components depicted that genotypes GIANT-3, AAI-347 and RAJ-4026 was found to be best for introduction of male sterility either through chemical hybridizing agent (CHA) or through transfer of ms gene from the wild sources or alien genes through biotechnological techniques in hybrid breeding programme in wheat. This hybrid showed highest positive significant heterobeltiosis (hb) and economic heterosis (he) values for grain yield per plant, number of grains per spike, number of effective tillers per plant and biological yield due to plasma gene effect in reciprocal crosses. The highest heterobeltiosis (hb) and economic heterosis (he) value for grain yield per plant was depicted by direct cross GIANT-3 x AAI-347 and reciprocal cross PBW-343 x GIANT-3.
Keywords: Heterosis, male sterility, nuclear gene, plasma gene, wheat.
