夏棉豫早1109新品系,是河南省农科院经作所以中抗5、中10、中657三个品种连续杂交、定向培育而成。该品系主要是把高产、早熟、抗病、优质四个性状统一协调起来,既具有较好的抗(枯、黄萎)病性能,又有较高的产量。突出的早熟性和优良的纤维品质。一、产量高:1989年国家攻关联试,平均亩产皮棉60.4公斤,比中10增产38.2%,居于第一位,增产达极显著水平。1990年河南省夏棉品种区试,平均亩产皮棉72.3公斤,比中14增产15.1%,居于试验第一位,增产达极显著水平。1990年河南省夏棉新品种生产试验结果,平均亩产皮棉68.3公斤,比中14
Summer cotton Yu early 1109 new lines, Henan Academy of Agricultural Sciences by the so anti-5, 10, 657 in three varieties of continuous hybridization, oriented cultivation. The strain is mainly to harmonize the four traits of high yield, early maturity, disease resistance and high quality, which not only has better disease resistance (wilt and wilt) but also higher yield. Outstanding precocity and excellent fiber quality. First, the high yield: 1989 National Research Association, the average per-mu yield of lint 60.4 kg, 38.2% increase over 10, living in first place, increased production reached a very significant level. In 1990, heilongjiang province varieties of cotton area test, the average per mu yield of lint 72.3 kg, 15.1% increase than in 14, living in the first test, yield reached a significant level. In 1990, the production of summer cotton new varieties in Henan Province showed that the average yield of lint cotton was 68.3 kg,
