Abstract
Genetic analysis of yield-related traits in bread wheat was carried out by crossing the drought sensitive cultivar Gusspard with two tolerant cultivars, BCW and Sardari. F1, F2, BC1 and BC2 progenies along with their parents were planted in randomized complete block design with three replications. Morphological traits such as flowering data, maturity data, spike weight, number of fertile spikes, peduncle length, 1000 seed weight, harvest index, were recorded. Results of weighted analysis of variance showed significant generation means squares for all traits. Therefore, analysis of generation means were examined using mutual scale test, which is performed in all generations simultaneously for each trait. In addition to additive and dominance effects, epistasis effect also played role in controlling the inheritance of all traits. Mean broad sence heritability for studied traits varied within the range of 0.44 and 0.89 Number of genes for the all traits was estimated to be approximately 1 to 3
