在1983—1985年,对南方4582个大豆品种进行了抗蝇性抗源鉴定。初筛时,于1983年8月和10月分别对2064个和3610个大豆品种进行测验。根据每品种10株的平均虫量,筛选出855个品种,连同新参加筛选的972份材料和感性品种,设立无重复的试区,于1984年8月再次进行筛选。将从第二次筛选出的219个品种于1985年设立了3次重复的试区,以虫量结合虫道进行鉴定,从中选出15个品种。这些材料可以供抗性机制和抗蝇育种研究之用。本文尚就叶柄的含虫量,主茎虫道长度与抗性分级标准的关系进行了讨论。
In 1983-1985, 4582 soybean varieties in southern China were tested for their resistance to flies. At the initial screening, 2064 and 3610 soybean varieties were tested in August and October 1983, respectively. According to the average insect population per 10 strains, 855 varieties were screened, along with 972 new materials and susceptible cultivars newly selected for screening. A repeat-free trial was set up and the screening was repeated in August 1984. Three replicates of the 219 varieties selected from the second screening were set up in 1985 to identify 15 insect species from the worm population. These materials can be used for resistance mechanisms and anti-fly breeding research. This article also petiole pest amount, the main stem worm lane length and resistance grading standards were discussed.
