This experiment was carried out to evaluate AVRDC mungbean lines (BC12 generation) to bruchids resistance.Two BC12 mungbean lines' resistance to bruchids were checked,and their recurrent parents (KPS1,CN60) were compared.The result indicated that two BC12 lines and their recurrent parents had no significant difference in number of eggs laid (NEL) and rate of eggs laid (REL).However,the differences of the number of adults emergence (NAE),the rate of adults emergence (RAE),the number of seeds damaged (NSD) and the rate of seeds damaged (RSD) were highly significant.Correlation coefficient revealed that there were significant positive correlation between NEL and NAE,NAE and NSD.The comparison of BC12 lines and their recurrent parents showed NSD was especially significant,indicating BC12 (KPS1) and BC12 (CN60) really being resistant to bruchids.
