1954年起为选育早熟陆地棉新品种,曾採用陆地棉品种“斯字五爱”和“波字611”等,进行杂交育种工作,通过后代分离淘汰,进行回交与自交和短日照处理,到1962年选出优良杂交系“铁五”(T_5)。1963—64年在石河子、安西、辽阳、朝阳、锦州、熊岳等地参加品种区域试验初步结果:“铁五”(T_5)品系生育期在內陆棉区137天,早于对照波字611品种2—3天;在辽河棉区143天,早于熊岳51号品种3—4天。产量在內陆棉区占第一位,增产籽棉8％,皮棉5.4％,在辽河棉区增产籽棉4.3％,皮棉7.2％。纤维主体长度29.1毫米,超过內陆、辽河两棉区的对照品种2.1毫米。 1965年继续参加石河子、辽阳等9处品种区域试验,并由中央农业部调出一部分原种赠送英雄的阿尔巴尼亚试种。目前在新疆生产兵团莫索湾良繁場就“鉄五”(T_5)品系中选出的“72—2”选系,进一步继续培育。
Since 1954, a new variety of early-maturing upland cotton has been selected. The cultivars of “Sword Five Love” and “Wave-shaped 611” have been used to carry out crossbreeding work, separated and eliminated through offspring, backcrossed and self- By 1962, the fine hybrid line “Iron Five” (T_5) was selected. 1963-64 Preliminary results of regional trial of varieties participating in Shihezi, Anxi, Liaoyang, Chaoyang, Jinzhou and Xiong Yue: The growth period of “Tiewu” (T5) strain was 137 days in inland cotton area, earlier than that of control word 611 Variety 2-3 days; 143 days in the Liaohe cotton area, earlier than Xiong Yue 51 varieties 3-4 days. Output in the inland cotton area accounted for the first, 8% increase in seed cotton, lint 5.4%, in the Liaohe cotton area 4.3% increase in seed cotton, lint 7.2%. The main body of fiber length 29.1 mm, more than the inland, Liaohe two cotton areas of the control species 2.1 mm. In 1965 continue to participate in Shihezi, Liaoyang and other 9 varieties of regional trials, and by the Central Ministry of Agriculture transferred some of the original species of heroic Albania trial planting. At present, the “72-2” selected from the “Tuan 5” (T_5) strain at the Xinjiang Production Corps Mosesowan Fair Complex continues to be further cultivated.
