| Abstract:
The objective of the study was to determine the interdependence of seven morphological characters in the bean using simple correlation coefficients and Path-Coefficient Analysis. The traits were plant height, height up to first pod, pod number per plant, seed number per plant, seed number per pod, 1000 seed mass, and seed yield or mass per plant. The study included five colored seed and nine white seed varieties. For the most part, the traits have been shown to be correlated, the intensity of the correlation ranging from low to extremely high. Negative correlation with other traits have been found in first pod height and 1000 seed mass. Analyses of the total effect of the traits on yield have revealed that pod number per plant has the greatest direct effect on yield in the bean varieties currently in use in Yugoslavia. The direct effect of seed number per plant is minimal, the high total effect being due to the indirect influence of pod number per plant. First pod height has a negative influence and seed number per pod and 1000 seed mass (seed weight) a positive direct influence on yield. | |
