摘要
在南京经过6年鉴定,从6724份国内外大豆资源中,发掘出对本地大豆食叶性害虫表现抗性的资源20份,包括对豆卷叶螟、斜纹夜蛾、大造桥虫等具有综合抗性的6份;主要抗豆卷叶螟的8份;主要抗斜纹夜蛾、大造桥虫的6份。其中大多数材料的抗性水平高于目前国际上常用的3个食叶性害虫抗源PI171451、PI227687、PI229358。一些抗性资源综合农艺性状优良,可作为抗虫育种的首选亲本。同时发掘出对本地大豆食叶性害虫表现感性的大豆资源12份。
Screening for source of resistance of soybeans of leaf feeding insects (LFI) was carried out in 1983, 1989, 1990, and 1992 1994 in Nanjing. Out of 6724 soybean germplasm accessions, 20 genotypes were identified to be highly resistant to LFI, including N2549 2, N1178 2 2, N5454 3, N3697, N3039. and N4908 with resistance mainly to bean pyralid, mugwort looper and cotton worm, N21400, N10403, N3018, N3400 1, N3854, N4029 3, N3155 1, and N2395 with resistance mainly to bean pyralid, and N5305 5, N3379 1, N21565, N20793, N23518 and N21551 with resistance mainly to cotton worm and mugwort looper. The resistance level of these genotypes in the testing years were higher than that of PI171451, PI227687 and PI229358. In the mean time, 12 genotypes were identified to be highly susceptible to LFI, including N20839, N20955, N21266, N117 1, N119 1, N681 1, N1327, N21550(mainly to bean pyralid), and N20865, N3289, N10172 2, and N20922(mainly to cotton worm and mugwort looper).
