Information on the variability and correlation between agronomiccharacters of mungbean accessions with their yield are importantfor supporting breeding program of the plant. A total of 350mungbean accessions were evaluated at Muara ExperimentalFarm, Indonesian Center for Food Crops Research and Development,Bogor, during the dry season of 2005. The experimentwas conducted in a completely randomized block design withthree replications. Each accession was planted in two rows of5 m long. Plant spacing was 40 cm x 20 cm, two plants per hill.Correlation and path coefficient analyses were used to quantifythe magnitude of the relationship between yield componentsand grain yield. The variability among the accessions wassignificant for most of the characters studied, especially fordays to maturity, plant height, pods per plant, and seed size.Among the yield components, the number of pods per plant andplant height positively correlated with the grain yield, but theseed size negatively correlated with grain yield. The directeffects of the number of pods per plant and plant height on seedyield as indicated by path coefficient were the highest, whileother causal effects were small or negative. Yield variation (1-R2) attributable to the nine yield component variables wasslightly high (61.23%), which means that mungbean accessionswith high grain yield should have sufficient plant heightand high number of pods per plant. Therefore, these parameters(number of pods per plant and plant height) can be usedas the selection criteria in mungbean breeding program. Thesecriteria can be visualized during bulk selection on the earlygeneration stage of F2 to F4, and subsequently on line developmentof individual plant (pedigree) of F5.
