摘要 鉴定了我国南方4,582份大豆资源对豆秆黑潜蝇的抗性。提出以茎秆虫量为指标、以筛选所得的10份高抗、10份高感材料为标准品种,将抗蝇性划分为5级的鉴定方法。抗蝇性鉴定结果未发现免疫材料,东南及长江下游地区的资源中有较好的抗性材料。抗蝇性属遗传性状,对抗蝇性的选择有效果,但该性状的遗传力较低。抗蝇性与生育期、分枝数、叶色、茸毛密度及茸毛着生状有关,与花色、种皮色、茸毛色及其粗细、长短等相独立。 An evaluation of 4582 entries of soybean germplasm from southern China to soybean agromyzid fly was carried but. The standard-variety grade system, with the number of maggots, pupae and pupae cases in stem as indicator and the 10 high-resistant and 10 high-susceptible entries screened out from this study as checks, was suggested for the evaluation of resistance to the pest. There was no immune material found, while among germplasm from the Southeast Area and Lower Yangtze Valley existed some entries with relative high resistance. This kind of resistance appeared to be inheritable, but only of low heritabi-lity value. In addition, the resistance was found to be related with growth period traits, number of branches, leaf color, and density and form of pubescence, but independent of flower color, seed coat color, and color, length, and thickness of pubescence.
