Association analysis among yield components in the three generations of durum wheat

Correlation analysis between grain yield and its component traits were carried out in the three generations namely, parents, F₁ and F₂ developed by 10 x 10 diallel cross (excluding reciprocals) in durum wheat. Among component characters grains per spike and tillers per plant would lead to higher yield in durum wheat. The antagonastic relationship between traits of economic importance suggested that intermating in early segregating generations for atleast 3–4 years need to be adopted. A mUltiple cross involving JNK-4W-14, A-9-30-1, Cocorit-71 and stork's’ will be most appropriate to generate the variability in desirable direction for isolating valuable segregants with desirable attributes.
