在2006~07和2007~08两个作物季,研究了不同基因型油菜在大田和筛房条件下对红蚜(Lipaphis erysimi,Kaltenbach)侵染的反应,以及不同生化成分与蚜虫侵染的关系。在不同基因型中,红衣菌在菜薹品种brown sarson CV上的群体数量显著增加。BSH1和rapa变种。黄色萨尔森简历。无保护地YST151分别为53.7和52.3个蚜虫/株。但在Eruca sativa CV上最低。T27(4.7个蚜虫/株)次之,carinata CV。DLSC2(20.9头/株)的产量损失最小,分别为5.79%和10.59%。幼苗死亡率的变化趋势基本相似,其中BSH1和YST151的死亡率最高,而T27在两个研究年份中均未见幼苗死亡率。各种生化成分分析表明,硫代葡萄糖苷、总酚和邻二羟基酚与蚜虫侵染呈负相关。T27和DLSC2中这些生化成分含量较高,是造成这些基因型蚜虫侵染率较低的原因。

英文摘要:
  Two years study was carried out during 2006-07 and 2007-08 crop seasons to study the response of different genotypes of oilseeds Brassica to Lipaphis erysimi (Kaltenbach) infestation both under field and screen house conditions and to find out the relationship of various biochemical constituents to aphid infestation. Among the various genotypes, the population of L. erysimi was significantly high on Brassica rapa variety brown sarson cv. BSH 1 and B. rapa var. yellow sarson cv. YST 151 in unprotected set i.e. 53.7 and 52.3 aphids/ plant, respectively. However, it was the lowest on Eruca sativa cv. T 27 (4.7 aphids/plant) followed by B. carinata cv. DLSC 2 (20.9 aphids/ plant) which suffered the least yield loss i.e. 5.79 and 10.59 per cent, respectively. Almost similar trend was observed in seedling mortality, which was the maximum in BSH 1 and YST 151, while no seedling mortality was observed in the case of T 27 during both the years of study. Analysis of various biochemical constituents revealed that glucosinolates, total phenols and ortho-dihydroxy phenols had inverse relationship with the aphid infestation. Higher amount of these biochemical constituents in T 27 and DLSC 2 was responsible for lower aphid infestation on these genotypes.
