Estimation of the genetic variability, heritability and genetic advance in the wheat genotypes (Triticum sp.) is most important in the plant breeding because, with the help of this study the plant breeder developed an improved variety of wheat. The present investigation has been carried out at Agricultural Research Station, Mandor, Jodhpur during rabi 2016-17 to evaluate thirty one genotypes of wheat to asses extent of genetic variability, heritability and genetic advance for grain yield and contributing character. The material was planted in randomized block design with three replications and observations were recorded on individual plant basis. Analysis of variance had shown highly significant variances among the genotypes for all the characters under study, indicated availability of wide spectrum of variability among the genotypes. The maximum percentage of coefficient of variation (GCV and PCV) were observed for number of tillers per plant followed by grain yield per plant, flag leaf area, harvest index, spike length, days to heading, plant height, 1000 grain weight, protein content and peduncle length. High heritability estimates were obtained for days to heading, harvest index, grain yield and number of tillers per plant. Expected genetic advance (GA) was observed to be high for number of tillers per plant, grain yield, harvest index, flag leaf area and days to heading.
