近年来,在乌孜别克共和国棉花选种和良种繁育科学研究所里,选育了很多新的早熟、丰产、纤维品质优良的细绒棉品种,目前表现最好的乃是C—6022与C—6015.C—6022属海岛棉型,是从2296×2352后代中多次单株选育而成的,为无限果枝,但较紧凑,株高90—100厘米.茎杆光滑,发蕾节位为5—6节.叶片中等大小、3—5裂.花大,黄色,花瓣基部有红心.苞叶较大,9—13锯齿.铃3—4室,长圆形,暗绿色,开裂良好.种子中等大小,尖端带毛.该品种在棉花选种所试验的结果,较5476—И早熟、丰产,抗枯萎病,品质属第一级.(表1)该品种从一九五八年开始进行国家品种区域试验,在各地表现良好.一九五九至一九六一年,三年的试验结果,产量较5476—И高出10—30%
In recent years, many new precocious, high-yielding and fine fiber varieties of fine cotton have been bred in the Institute of Cotton Seeds Selection and Seed Breeding in Uzbekistan. Currently, C-6022 and C-6015 .C-6022 is a sea island cotton type, is from 2296 × 2352 offspring in many single plant breeding, is an infinite fruiting branch, but more compact, plant height 90-100 cm. Stem smooth, 5-6 leaves medium-sized, 3-5-lobed flowers large, yellow, basal petals with red heart, bracts larger, 9-13 serrated, 3-4-ring bell, oblong, dark green, cracking well. The medium size and sharp hair with the seeds.The results of cotton varieties tested in this variety are more precocious than 5476-И, with high yield, resistance to Fusarium wilt and the quality belongs to the first grade (Table 1) The variety started from 1958 Regional trials of the national varieties performed well in various parts of the country, and from 1959 to 1961, the results of the three-year trial showed that the output was 10-30% higher than that of the 5476-И.
