One hundred and twenty triple teat cross families and a set of six basic generations arising from two breadwheat crosses (9 0 x HD 2009, C 591 x WL 711) were grown in three blocks of randomized block design to detect additive, dominance and epistatic components of genetic variation for grain yield and tillers/plant, grains/spike, grain weight, harvest index, spikelets/spike,and spikelength. The results obtained by triple test cross and modelfitting analysis were in agreement with each other. Additive and additive x additive type of gene actions are more predominant in this material.
