一个兼有抗虫、优质、无毒的棉花新品系在河北省农科院植保所育成。 W 82-1棉花新品系是1982年引进抗虫品系SP-37×HG—E—12的杂交后代中选出的一个无蜜腺光叶无腺体的单株选育而成。经过3年来的试种对比和观察,除了产量和推广种大体相同以外,还有以下优良性状。 1.抗虫性:它既抗棉铃虫又抗棉蚜。据1985年在抗棉铃虫鉴定的两个试验中调查结果,W 82-1能减少棉铃虫落卵量42.2％和63.4％;在1984年20个
A combination of insect-resistant, high-quality, non-toxic new cotton plant in Hebei Academy of Agricultural Sciences Plant Protection bred. The new line W 82-1 was selected from a single non-nectary gynogenetic plant selected from the cross of offspring introduced with the insect-resistant line SP-37 × HG-E-12 in 1982. After three years of trial comparison and observation, in addition to the same output and promote the same species, there are the following excellent traits. 1. Insect resistance: it is resistant to both cotton bollworm and cotton aphid. According to a survey conducted in two tests against cotton bollworm in 1985, W 82-1 reduced the amount of eggs laid by the cotton bollworms by 42.2% and 63.4% respectively. In 1984, 20
