摘要
以河北省品种审定委员会2004年公告审定品种的主要性状为依据, 采用主因子分析等方法, 分析了审定的11个棉花品种的农艺性状差异和种植分类。结果表明, 所有品种仅适于在中熟和中早熟2个区域推广应用; 冀棉298和GK12抗黄性好, 适于在黄萎病较重的重茬重病地种植; 丰抗棉1号霜前花率高; 邯368和邯682抗黄性较差, 适于在高水肥、常与禾本科作物倒茬的轻病地种植。
The analysis on differences of agronomic characters and c luster according main different cultivated characters of new cotton cultivars ex amined and approved by Hebei Province Crop Variety Examination Committee in 2004 had been made. The result showed that all cultivars adapt well to mid-early an d mid-materity cotton areas in Hebei province. Synthetical agricultural charact er of cultivars bred by same institute is more similar than that of others.With higher resistance to Verticium Wilt,Jimian-298 and GK-12 adapt well to the repea ting-culture cotton field. Fengkang-1,Han-368 and Han-682 adapt to the field wh ich alternates with gramineous crops,as the rate of blossom before frost of Fen gkang-1 is high and the resistance to Verticium Wilt of Han 368 and Han 682 is higher.
