摘　　要：利用原产于印度的抗豆象栽培绿豆品种V2709与农艺性状优良的感豆象推广品种中绿1号(VC1973A)杂交,以杂交种F1、F2为试验材料,通过田间农艺性状调查、室内人工接虫鉴定及多元相关分析等,研究V2709中所包含的抗豆象特性的遗传背景。结果表明V2709的抗豆象特性由一对显性基因控制;通过相关性分析发现其抗虫性与植株高度呈极显著正相关,与主茎节数呈显著正相关,而与其他性状无明显相关性。By using V2709, a mungbean cultivar with bruchid resistance from India, and VC1973A, a bruchid susceptible variety as parents, F1 and F2 generations were developed to investigate the agronomic traits, identify the bruchid resistance and conduct statistics analysis. The result showed that the bruchid resistance of V2709 is controlled by one single dominant gene. This resistance character had positive correlation with plant height and node numbers, but had no correlation with other traits.
