Summary
Two methods were used to analyse the relationship between 14 traits recorded from an 8×8 diallel cross between varieties of spring wheat. The stepwise regression analysis which introduces characters into a multiple regression equation in the order in which they contribute to yield, together with factor analysis was used to analyse the same dependence structure. The 14 causes were grouped into the basic factors which generate the dependence structure. The two methods were found to give complementary information. The way in which such knowledge would assist the plant breeders in making selections was demonstrated.
