Detection of additive, dominance and epistatic variation in wheat using triple test cross method

Sixty progeny families were produced by crossing 20 wheat varieties with three male testers (WH 147, WH 542 and their F₁) in a triple test cross fashion to detect epistasis and test and estimate additive and dominance components of genetic variation. Epistasis was present for plant height and 1000-grain weight in both environments. Testers were adequate for grain number. Additive component played a greater role in the control of almost all the six characters.
