河北省农林科学院植保研究所针对棉花生产枯黄萎病发生严重和近年来河北省棉花种植向黑龙港等地区扩大发展,该区多属干旱和半干旱气候特点。于1986年选择高抗枯萎病能力强381为母本与224—14和V82—5混合花粉为父本杂交(其中224—14丰产性好,V82—5具有一定抗棉铃虫且纤维品质优良)。连续多年在重枯、黄萎病圃定向选育和南繁加代,于1990年出圃育成。该品系现已通过河北省区试小区试验和大区生产试验,并于1996年4月河北省品种审定委员会通过予审。 一、主要特征特性 171—6属陆地棉中熟品种,生育期129—142天,株型塔形较松散,茎秆硬,叶片中等,铃卵圆形中等偏大,铃咀尖壳薄,铃重4.8—5.2g,吐絮肥畅,子
Plant Protection Institute of Hebei Academy of Agriculture and Forestry for the production of cotton withered wilt disease serious and in recent years, Hebei Province, cotton planting to expand to the region of Heilongjiang, which is mostly arid and semi-arid climatic characteristics. In 1986, the selection of high resistance to Fusarium wilt 381 as the female and 224-14 and V82-5 mixed pollen as the male parent (which 224-14 good yield, V82-5 has a certain resistance to bollworm and fiber quality excellent) . For many years in the heavy wilt, Verticillium wilt directional breeding and the South Fan generation, in 1990 nursery nursery. The strain has now passed the trial of Hebei district test area and the production test of large area, and passed the trial of the Hebei Province Variety Approval Committee in April 1996. First, the main characteristics of 171-6 is a medium-upland cotton cultivars, the growth period of 129-142 days, plant type tower loose, stem hard, medium leaves, bell oval medium large, bell Tsui tip shell thin, Bell weighs 4.8-5.2g, pour floc fertilizer smooth, child
