Abstract
The study was carried out at the Center for Scientific Agricultural Research in Hama, General Commission for Scientific Agricultural Research, Syria, during the 2022/2023 agricultural season with the aim of studying the phenotypic correlation coefficient and path analysis of some phenological and morphological traits and yield components (days to flowering, days to maturity, plant height, number of pods on the plant, number of branches per plant, weight of 100 seed, seed yield) for 12 faba bean genotypes. The experiment was arranged in a randomized complete block design (RCBD), with three replications. The results showed that there was a positive and significant correlation between the seed yield trait and the days to flowering (r=0.634**), days to maturity (r=0.510**), plant height (r=0.777**), number of pods on the plant (r=0.657**), weight of 100 seed (r=0.898**). Path analysis clarified that weight of 100 seed (0.7553), number of pods on the plant (0.2699), had a direct effect on seed yield, In addition to the indirect effect of weight of 100 seeds on plant height (0.6412), days to flowering (0.4822), days to maturity (0.4082), and number of pods on the plant (0.4584). The days to maturity, the number of pods on the plant, and weight of 100 seeds are among the characteristics that contribute most to increasing seed yield, as their contribution rate reached (70.72%).
Key words: phenotypic correlation coefficient, path analysis, seed yield, faba bean.
