ABSTRACT
Mung bean (Vigna radiata L.) is one of the important food legumes with considerable market potential, but its production in Riau Province remains relatively low, so demand is still supplied from other regions. This study aimed to determine the variability, heritability, selection response, and phenotypic correlations among various seed development traits and yield components in mung bean. The research was conducted at the Experimental Farm and Plant Breeding Laboratory, Faculty of Agriculture, Universitas Riau, from March to July 2024. The experiment was arranged in a randomized block design (RBD) using 15 mung bean varieties with three replications. The observed characters included days to flowering, days to maturity, plant height, number of primary branches, seed dry weight at 15 and 22 days after pollination, seed dry weight at harvest, seed filling rate, effective seed filling duration, seed yield per m², and 1000-seed weight. The results showed significant genetic variability among varieties for most of the observed traits. Wide genetic variability was found in flowering time, maturity time, plant height, seed dry weight, seed yield, and 1000-seed weight. Heritability estimates varied from low to high, where seed filling rate and effective seed filling duration had low values, while the other traits ranged from moderate to high. Phenotypic correlations revealed positive associations between several traits and seed yield per m², suggesting their potential as selection criteria. The highest selection response was found in seed yield per m², while the lowest was in seed filling rate and effective seed filling duration. The regression analysis showed that days to flowering, number of primary branches, seed dry weight at 15 days after pollination, seed dry weight at 22 days after pollination, seed dry weight at harvest, and effective seed filling duration can be used as predictors for seed yield per m². The traits of days to flowering, days to maturity, plant height, number of primary branches, and seed dry weight at 22 days after pollination were identified as predictors for 1000-seed weight.
Keywords: Mung bean, genetic variability, heritability, phenotypic correlation, selection response.
