中99是中国农科院棉花研究所汪若海研究员主持育成的一个具有多种抗性的棉花种质系,对棉蚜和棉红铃虫有较好的复合抗性,对棉枯萎病和黄萎病有较强的兼抗性,且具有优良的综合农艺性状。其主要特点是:一.将抗虫性与抗病性结合起来,是棉花多抗育种可利用的有效抗源和种质材料。据“七五”期间国家攻关课题抗虫棉花新品系选育协作组及抗虫资源鉴定协作组,1985—1987年三年网室及田间鉴定试验,中99伏蚜蚜害指数为0.37,低于对照品种非洲E40及中棉12,抗蚜性居16个品系之首。三年多点试验表明,中99抗蚜性强而稳定,评定为
99 is a cotton germplasm with multiple resistance cultivated under the auspices of Wang Ruohai, a researcher at Cotton Research Institute of Chinese Academy of Agricultural Sciences. It has good composite resistance to cotton aphid and cotton bollworm, Verticillium has a strong and resistant, and has excellent agronomic traits. Its main features are: First, combining insect resistance and disease resistance, it is an effective source of anti-germplasm and germplasm that can be used for cotton breeding. According to the “Seventh Five-Year” period national research topics new line of insect-resistant cotton breeding collaboration group and the identification of insect resources collaboration group, 1985-1987 three-year network room and field appraisal test, 99-volt aphid harmful index was 0.37, low In the control varieties of Africa E40 and cotton 12, anti-aphids living in the first 16 lines. More than three years of tests showed that in 99 anti-aphid strong and stable, as
