1980年,在我县南贾公社下鲁大队,用抗病品种86-1作母本,和中棉所7号进行了人工杂交。从7月16日到8月20日,共杂交近2万朵花,杂交结铃率80.1%,获得杂交种子30余斤。1981年,下鲁大队进行了杂种一代与母本86-1的比较试验,结果证明杂种一代生长势强,抗病性好,产量和质量都明显优于母本。一、试验设计小区试验土地肥沃,灌排方便;前作棉花,重病田。小区面积0.4亩;宽窄行种植,宽行2.4尺,窄行1.4尺,密度为4千株/亩;地膜覆盖,4月7日播种,4月13日出苗。
In 1980, under the commune in our county Lu Jia Brigade, 86-1 with the resistant varieties as the female parent, and the Cum Cotton Institute on the 7th artificial hybridization. From July 16 to August 20, a total of nearly 20,000 hybrid flowers, hybridization boll rate of 80.1%, access to more than 30 pounds of hybrid seeds. In 1981, the Xia Lu Brigade carried out a comparative experiment between the hybrid generation and the female parent 86-1. The results showed that the hybrid generation has strong growth potential, good disease resistance, and significantly better yield and quality than the female parent. First, the experimental design Experimental plots of fertile land, irrigation and drainage convenience; before cotton, severe disease. Area of 0.4 acres of plot; width line planting, wide line 2.4 feet, narrow line 1.4 feet, density of 4 plants / mu; mulching, sown April 7, April 13 emergence.
