Abstract: In this study, a set of twenty genotypes of Wheat (Triticum aestivum L.) were evaluated over two years from 2015-16 to 2016-17 to assess the genetic analysis of these genotypes for yield and its contributing traits over years and environments. These were evaluated in randomized complete block with 3 replications and two dates of sowing i.e. 3rd week of November (timely sown) and 1st week of January (very late sown). Significant variability were found in all the environments for all the traits. Higher magnitude of both coefficients were observed for traits viz., number of dead tillers plant-1, number of grains plant-1, yield plant-1 and number of effective tillers plant-1/number of ears plant-1 in all the sowing conditions. Traits viz., biological yield plant-1, yield plant-1, ear head length (cm), peduncle length, harvest index (%) and ear weight governed by additive gene action in all the environments. Therefore, selection for grain yield plant-1 can be done through biological yield plant-1, ear head length (cm), peduncle length, ear weight and harvest index (%).
