The present investigation was under taken to examine the genetic variability and relationship between traits among the 57 genotypes of bread wheat collection of diverse nature. Genetic variability and association. and its components, in cross involving 10 parents of wheat varieties viz., MP 4010, MP 3288, MP 1358, MP 1203, HI 1544, HI 1605, HI 1634, CG 1029, HD 2967 and DBW 110 and their 45 F1’s (excluding reciprocal) obtained through dialed cross were evaluated during Rabi 2022-23 at AICRP On Wheat, Zonal Agricultural Research Station, Powarkheda, Narmadapuram. Observations were recorded on 13 morphological traits. Collected data were subjected to assess the genotypic and phenotypic variance, genotypic and phenotypic coefficient of variability, heritability, and genetic advance as per cent of mean. Observations were documented for twenty characters namely Days to 50% heading, days to maturity, plant height, peduncle length, effective tillers /plant, spike length, number of spike/plant, number of spikelet’s/spike, number of grains/spike, 1000-grain weight, biological yield/plant, harvest index, protein content, wet-gluten, hectoliter weight, canopy temperature depression, chlorophyll content, flag leaf area, heat susceptibility index, and grain yield /plant high heritability in addition to high genetic advance as per cent of mean pointing towards that it would be effective to employ simple selection schemes to fetch genetic enhancement in desired track for mentioned characters.
