Summary
The efficiency of three analyses, namely, Designs I and II of Comstock and Robinson (1952) and standard Design III analysis of Kearsey and Jinks (1968), was compared in the F2s of three wheat crosses (Norteno 67 x HD 1982, HD 1982 x Moti and Sonalika x Moti) for plant height, spikelets per spike and yield per plant. The three analyses showed a remarkable agreement in estimating the additive (D) component for all three characters in all three crosses. But, as regards the estimation of dominance ] (H) component, standard Design III analysis proved to be more efficient than the other two analyses in crosses 2 (HD 1982 x Moti) and 3 (Sonalika x Moti) for all three characters except spikelets per spike in cross 3.
