摘　　要：针对陆地型长绒棉鲁原 343在生产中秋桃比例较高的问题 ,我们以美国 33B为对照 ,田间条件下对其铃性状的空间分布特点进行了观察研究。结果表明 ,鲁原 343果枝的结铃数、单铃重和棉纤维长度具有较高的中部优势 ,在上部则明显降低 ;其子指、铃壳重具有较强的上部优势 ;衣分的中部优势不明显。In order to solve the problem of high autumn boll rate of upland cotton cultivar with extra long staple(Luyuan 343),the distribution for boll traits of an upland cotton with extra long staple(luyuan 343) were studied in field,compared with an upland cotton cultivar(America 33B).The results showed that Luyan 343 had advantage on boll number and boll weight and lint length on the median of plant,as well as seed index and boll crust weight on upper part of plant.
