Abstract

Path coefficient analysis is frequently used for development of selection criteria on various type of plants. Path analysis on this research was conducted to find the selection criteria of yield component which directly affect bean weight. In addition to the value of path analysis coefficient, genetic variation coefficient, heritability and the value of genetic progress were also studied. The study was conducted at the Indonesian Coffee and Cocoa Research Institute. The research used randomized complete block design consisting of 14 accession numbers and each consisting of three replications. Pod girth, pod length, pod weight, wet beans weight per pod, number of normal beans per pod, number of abnormal beans per pod, dry weight per normal bean, and shell content were observed. The results showed that the pod weight character had an important role in determining the dry weight of normal bean. The character had a positive genotype correlation coefficient values which was high and significantly different (r=0.46) for dry weight per normal bean, considerable direct influence (P=0.479), moderate of the genotype variation coefficient (9.6%), and high genetic progress (95.23). Character of wet bean weight per pod could also be used indirectly for the selection criteria for dry weight per normal bean based on genetic variation coefficient value (11.88%), genetic progress value (82.48), and direct effect on dry weight per normal bean had positive value (P=0.006). Key words: Selection criteria, dry weight per bean, path analysis,Theobroma cacaoL.

Abstract

Cocoa is recalcitrant seed which it has the high water content and the deterioration goes quickly. The distribution of cocoa seed need longer time and it will decrease the quality of cocoa seed and cocoa seedling. The research aimed to determine of effectiveness seed soaking with Beauveria bassiana after storage during the distribution of seed. This research was conducted in Indonesian Cofee and Cocoa Research Institute. The research was conduct using randomized complete block design with a factorial arrangement. First  factor was the  storage period  of two days (L2), three days (3 hari), four days (L4), five days (L5), six (L6) and seven days (L7). The second factor was seed soaking with Beauveria bassiana (B1) and seed soaking with fungicide (B0). The result showed that storage periode had significant effect on  plant height and stem diameter. Seed soaking with Beauveria bassiana showed significant effect on plant height. The interaction between storage periode and seed soaking with Beauveria bassiana had no significant effect on the height of seedling, stem diameter and leaf number of seedling.
