영문 초록

This study was conducted to evaluate the possibility of developing new mung bean lines through the understanding of genetic variation in agronomic characters as well as introgression of resistance gene to disease and insect in hybrid between mung bean and black gram. In advanced generations, the percentage of aborted seed, incidence of plant death and sterile plants were reduced. The number of bivalent of chromosome configuration in meiosis metaphase Ⅰ was increased according to generation advances, suggesting that chromosome configuration was closely related to the interspecific hybrid fertility. Correlation coefficients of yield and pod number were varied widely as generation advanced, but those of plant height and pod length were reduced. Crude protein and amino acid content of hybrid progenies were highter than those of parents as generation advanced. Hybrid progenies were more resistant than mung bean to Cercosporal Leaf Spot and Powdery Mildew in field. Resistance to bruchid beetles in the laboratory test was shown in all hybrid progenies.
