【摘要】 <正>In recent years,weedy rice is increasingly becoming a serious problem in rice production.On the other hand,weedy rice can be used as new germplam resources for rice breeding.This paper reports a study on the botanical characteristics of weedy rice found in Jilin Province of Northeast China.Phylogenetic origin of weedy rice was estimated based on polymorphic banding patterns derived from 26 pairs of SSR primers.For the botanical traits,the majority of the weedy forms were taller than the cultivated rice;更多还原
