dc.description.abstractStudying the relationships between main quantitative traits gives an opportunity the results of selection on certain traits to be predicted and the breeding process to be improved. In the present investigation, it was made an assessment of correlation dependencies in pea lines with a different morphology of the compound leaf: ordinary ("AFAFTLTLSTST"); afila (semi-leafless -"afafTLTLSTST"); pleiofila (tendril acacia -"afaftltlSTST"). The results showed a positive significant correlation of the plant height with 1stpod height (r=0.701, 0.390, 0.386) in the three pea morphotypes, and with the pods number per plant (r=0.560, 0.558) in afila and pleiofila type. Positive, statistically significant relationships were found between seed weight per plant with the number of pods (r = 0.516) and seeds (r = 0.567) only in ordinary leaf morphotype, and with the 1000 seeds weight (r = 0.448) in pleiofila type. The number of pods per plant and number of seeds in a pod had the maximum positive direct effect on seed productivity in afila and pleiofila types of leaves. In genotypes with the ordinary type of leaves, selection criteria can be the number of seeds per plant (0.890) and plant height (0.420), and in pleiofila type -1000 seeds weight (0.596). In the genotypes of the three morphotypes, the traits of number seeds per plant (0.850, 0.042, 0.075) and number of seeds in a pod (0.070, 0.421, 0.373) positively influenced the seed productivity.
