Correlation Studies of 21 Traits in F2 Generation of Groundnut (Arachis hypogaea L.)

S.T. Kotzamanidis, N. Stavropoulos and C.G. Ipsilandis

Abstract:
Correlation between twenty-one traits was studied in plants of F2 generation derived from crosses of groundnut varieties. Also, correlation for the same traits of plants was studied within the four types of crosses used: Virginia × Virginia, Valencia × Valencia, Virginia × Spanish and Virginia × Valencia. Significant positive correlation have been found in the total of plants with r values ranging from 0.22 to 0.46 for pod yield with pod distance from the main root, seed length, seed width, pod length, pod width, grams/100 pod, grams/100 seed, shelling percentage. From the four types of crosses and for the same traits, in relation to the pod yield, the type cross Virginia × Virginia showed the most significant positive correlations followed by types Valencia × Valencia, Virginia × Valencia and Virginia × Spanish. Selection based on plants that have shorter pod distance from the main root and larger seed size and also larger 100 pod weight, could increase peanut yielding performance.
