IMPACT OF INTERMATING ON POPULATION MEAN AND GENETIC ADVANCE IN WHEAT (Triticum aestivum L.em.Thell)

Description
Summary:The effect of intermating in F2 generation on mean and genetic advance in two crosses of wheat WH 416 × HD 2160 and WH 416 × HD 2329, was studies. The mean and genetic advance of all the five characters viz. tillers per plant, grains per ear, grain weight per ear, biological yield per plant and yield per plant, were increased after first cycle of intermating. Second cycle of intermating further showed its positive impact on mean and genetic advance. It appears that integration of atleast one or two cycles of intermating with conventional breeding programme may prove highly useful in generating poromising wheat genotypes having high yield potential.
