以从美国引进的早熟春播品种 B早为母本,与中棉所16 号抗病系杂交,成功选育出早熟、高产、优质、抗病短季棉品种中棉所27 号。试验结果证明:中棉所27 号早熟性好,生育期108d;产量高,各类试验均居第一,霜前皮棉平均增产20% 以上;品质优良;具有多抗性和广阔的适应性。在选育过程中,应用生化测试和异地选育方法,加强早代选择,提高了育种效率。
The early spring cotton sowing variety B introduced from the United States was used as the early female parent and crossed with the resistance line 16 of Zhongmian No. The results showed that: the cotton variety No.27 was good in early maturity and the growth period was 108d; the yield was high, the first rank was in all kinds of tests, and the average lint yield increased more than 20% before the frost; the quality was good; the resistance was multi-resistant and the broad adaptability. In the breeding process, biochemical tests and off-site breeding methods are applied to enhance the selection of early generations and improve the breeding efficiency.
