Abstract:

In order to provide a valuable resistance source for the cultivation of Myzus persicae(Sulzer) resistant varieties, 373 tobacco germplasm resources were evaluated by in vitro leaf method. The selectivity of Myzus persicae (Sulzer) to different tobacco varieties was analyzed, and the resistance of Myzus persicae(Sulzer) was evaluated according to the evaluation method of Myzus persicae(Sulzer) resistance of tobacco varieties. The results showed that the Myzus persicae(Sulzer) had feeding selectivity to different tobacco varieties. Thirteen varieties with low selectivity to tobacco aphids were screened out, among which Shuba 2139, Shuba 2136, Heimiaomaoyan, Huangmiao 2230, Baijiancao 2489, Shuba 2129, Shubalaomuji 2113 and huangmiaosongbian were local varieties, and Jiyan 5, Yuyan 13, Y102, Longjiang 911 and 664-01 were domestic bred varieties. Seventy-eight varieties with lower selectivity were screened out. These varieties can be used as candidate materials for further identification of Myzus persicae(Sulzer) resistance. The number of tobacco with medium selectivity was the highest (32.44%), followed by tobacco varieties with high selectivity to Myzus persicae(Sulzer)(28.42%). The proportion of varieties with low selectivity to Myzus persicae(Sulzer) was small, and the genetic basis was narrow.
