育种抗虫是防治害虫的途径之一。现摘录一种国外选育抗红铃虫棉花品种的试验方法,供参考。 首先采集几百个比较原始棉花品系的棉铃,用干冰冰冻,运回实验室,将棉铃破开,分为果皮(铃壳)和棉铃内部物质两部分,配成标准饲料,以供饲养红铃 Breeding insect resistance is one of the ways to control pests. Now extract a foreign breeding test of cotton bollworm varieties for reference. First, hundreds of cotton bolls were collected from raw cotton lines, frozen in dry ice and transported back to the lab. The cotton bolls were broken and divided into two parts: the peel (boll shell) and the cotton boll internal material, and served as a standard feed for rearing red bell
