摘要
对引进巴基斯坦的54份棉花种质材料进行了田间鉴定。结果表明:引进材料类型较丰富,有陆地棉、海岛棉和瑟伯氏棉。在陆地棉材料中共鉴定筛选出矮秆类型材料3份,子指11 g以上的高子指材料3份,比强度>34 cN/tex的高强纤维材料2份,纤维长度>33 mm的中长纤维材料2份,个别性状的变异系数较大,可选择性强。通过对其利用,筛选出较高配合力的品系3个、抗虫、抗黄萎病品系1个、低酚抗虫品系1个、早熟品系1个和抗高温材料1个,说明该批引进种质在抗高温、抗病、改良纤维品质和提高产量等方面具有较高利用价值。
Fifty-four shares germplasm resources introduced from Pakistan were identified. The results showed that these germplasm resources were abundant. There were upland cotton, sea-island cotton and Thurberi cotton. There were three shares short-stemmed type （height 〈 60 cm）, three shares of high seed index （ 〉 11 g）, two shares of high strength fiber （ 〉34 cN/tex）, two shares of middle length fiber （2. 5% span length 〉 33 mm）in the upland cotton materials. Among them, variance coefficient of individual character was bigger. Several varieties including one share high combing, one share resistant insect and resistant verticillium wilt, one share low gossypol, one share early mature and one share high temperature resistance were selected.
