摘要
通过对2011—2013年优异短季棉品系生育性状、产量性状和纤维品质的比较,并分析不同年份各性状的变化趋势。结果表明,近年来,晋南地区在短季棉育种中取得了巨大进步,生育期缩短至105 d以内,铃大、衣分高,产量显著提高,纤维品质符合纺织工业要求,有的甚至达到优质棉标准;筛选出6个早熟、高产、优质的品系。有些品系个别性状(如高衣分、上半部平均长度长、比强度高)非常优异,可通过杂交、回交等手段将优良性状聚合,打破遗传负相关,选育综合性状优良的短季棉新品种。
Some excellent short season cotton strains from 2011 to 2013 in southern Shanxi were selected to analyze the trend of each character such as growth character, yield and fiber quality in different years. The rusuh showed that it made progress in the short season cotton breeding in recent years in southern Shanxi, the growing period was reduced to within 105 days, big boll, high lint, yield in- creased significantly, fiber quality conformed to the requirements of the textile industry, some even reached the standard of quality cotton. We could screen out six early maturity, high yield and high quality cotton strains. Some strain traits such as lint, fiber length and strength were very excellent, by cross and backcross methods fine properties could be polymerized, broke the genetic negative correlation, bred better comprehensive characters of short season cotton varieties.
