【 摘 要 】

This research was aimed to study and to estimate the variance components, broad sense heritability, genetic advance, expected of genetic advance, correlation, direct effect, and indirect effect from several characters to potential yield. This research conducted at the Pusat Kajian Hortikultura Tropis (PKHT) IPB experimental field in Tajur and Plant Breeding Laboratory, Department of Agronomy and Horticulture, IPB. Population used the P1 (BCS-3), P2 (BCS-7), and F3 (BCS-3 x BCS-7) genotypes. The single plant method was used in this observation. The time of flowering, time of harvest, pod weight, pod diameter, pod length, seed per pod and 100 seed weight were had low genetic variability. The pod beak length, pod total per plant and yield potential characters were had medium genetic variability. The time of flowering, time of harvest, pod beak length, seed per pod, pod per plant, and yield potential were had medium to high of broad sense heritability with high genetic advance. Then, 100 seeds weight was had low heritability with high genetic advance. The pod length, pod diameter, and pod weight were had low heritability and low genetic advance. A positive correlation and a higher direct effect to yield potential were showed by the pod weight and pod total per plant. Some qualitative references were suggested become important characters for improving french bean yield in this population.
