摘要
棉花新品种酒棉15号为酒泉市农业科学研究所以酒棉1号为母本、905为父本杂交,经定向选择、航天搭载系统选育而成。该品种纤维上半部平均长度30.5 mm、整齐度指数86.5%、断裂比强度29.9 cN/tex、麦克隆值4.3、伸长率5.9%、反射率75.8%、黄度7.9、纺纱均匀性指数157,在2010年甘肃省棉花新品种生产试验中,皮棉平均产量为1 953.0 kg/hm2,比对照品种酒棉8号增产10.6%,抗枯萎病。适宜于甘肃河西走廊及生态条件类似棉区种植。
Jiumian 15 was a new cotton variety bred by selected with the parental combination of Jiumian 1/905.The results showed that the upper half of the varieties of fiber length was 30.5 mm,the uniformity index was 86.5%,the specific breaking strength was 29.9 cN/tex,micronaire value was 4.3,elongation was 5.9%,the reflectivity was 75.8%,yellowness was 7.9,spinning evenness index was 157.In 2010,the average yield of was 1953.0 kg/hm2 and 10.6% higher than of the check Jiumian 8 in the production test of cotton new varieties in Gansu province.In addition,Jiumian 15 was resistance to fusarium wilt.It is suitable to plant in the region of the Hexi Corridor and other similar ecological areas.
