Abstract: The present investigation carried out with 19 parents (15 lines and 4 testers) and 60 F_1’s evaluated in a RCBD having three replications during Rabi 2017-18 to assess the magnitude of genetic variability parameters heritability and genetic advance in spring wheat. Sixteen quantitative different yield and quality traits viz; days to 50%, flowering, days to maturity, plant height, flag leaf area, productive tillers/plant, spike length, spikelets/spike, biological yield/plant, grains per spike, harvest index, 1000 grain weight, gluten content, protein content, ash content, grain yield/plant and phenol colour reaction (grading) included in study. The results corresponding to analysis of variance showed highly significant differences prevail among the genotypes for all the traits. The magnitude of PCV was higher than the (GCV) for all the characters under studied. This indicated that the variability for these traits in the genotypes was not much affected by the environments for the expression of these characters. High heritability coupled with the high genetic advance in % of mean was observed for grain yield/plant, biological yield/plant and ash content this indicated that these traits may be relied upon for selection of the genotypes for improvement in wheat.
