摘要: 对水稻植株农艺性状与稻米直链淀粉含量之间的关系进行了研究,结果表明:除千粒重和分蘖数与直链淀粉含量呈负相关外,其余各性状与其都呈正相关。与直链淀粉含量关联度较大的性状主要是株高、单株产量、粒长、剑叶面积和穗颈弯曲度等。

Abstract: In this paper, the relation of amylose content and agronomic traits of rice was studied. The results indicated that the relation between all agronomic traits and amylose content was positive correlation except the 1000-grain weight and the number of tillering was negative correlation. The related degrees order of main traits to amylose content was plant height > yield per plant> grain length>flag leaf >the curve degree of panicle.
