棉花抗虫育种,国外已研究了几十年。1965年Kamel等曾选出了抗红蜘蛛和抗棉蚜虫的多毛(804根/cm~2叶)品种“巴蒂姆101”。对于棉花茸毛性状的抗蚜性研究报道很多,但说法不一。近年来,在国内抗蚜育种已引起人们的兴趣和重视。本文是报道在大田发现的一极密毛单株及其衍生后代所做的抗蚜鉴定。 Cotton insect breeders abroad have been studied for decades. In 1965, Kamel et al. Selected the batik 101, a hairy (804 root / cm ~ 2 leaf) variety resistant to both red spiders and cotton aphids. There are many reports on the resistance of cotton hairy traits to aphids, but different opinions. In recent years, domestic aphid breeding has aroused people’s interest and attention. This article reports the identification of aphids against aphids in a single, densely populated single plant and its derived offspring found in the field.
