棉花新种质系的性状鉴定与育种利用评价
2011-2012年对142份新引进和自主创造的棉花种质资源进行生育性状、产量性状、纤维品质性状的鉴定.结果表明:该批材料均为陆地棉种质,类型较丰富.共鉴定筛选出株高60 cm以下的矮秆类型材料4份,子指15.5 g以上的高子指材料17份,单铃重6 g以上的材料有22份,比强度在32 cN/tex以上的高强纤维材料60份,2.5%跨长在32 mm以上的材料2份.根据该研究结果,我们筛选出了34份具有优异性状的材料,可为选育大铃、高籽指、高强纤维的种质提供资源....

Bibliography: | Cotton; Cermplasm; Character; Identification; Appraisal 51-1213/S Characteristics of 142 introduced and autonomous breeding cotton germplasm were studied in maturity, yield, fiber quality in 2011 -2012 years. The results showed that all the germp|asm belonged to upland cotton with a wild range of types. Several types were screened out,including 4 accessions of short-stemmed type( hvight 〈60 cm) ,17 accessions with high seed index ( 〉 15.5 g) ,22 aocesslons with high boll weight( 〉6 g) ,60 accessions with high strength ( 〉 32 cN/tex ) ,2 accessions with middlelength fibre (2.5 % span length 〉 32 nun). Based on this, 34 accessions germplasm with various excellent traits could be used as potential breeding material for selection of big-boll, high-seed index, high-strength-fibre varieties.
