两种生物型江都杂草稻不同栽播密度对水稻生长的影响及其与栽培稻的亲缘关系
Effect of Two Biotypes of Jiangdu Weedy Rice at Various Transplanting Densities on Growth of Cultivated Rice and Their Genetic Relationship
摘要
Abstract
To explore biotypes, genetic characteristics of weedy rice in Jiangdu, Jiangsu Province, China, and their genetic effect on yield of cultivated rice, morphological characteristics were detected and cluster analysis was conducted based on SSR markers. The results showed that the weedy rice materials can be divided into two biotypes: One is dwarf, including JDWR-A and JDWR-C. the other one is tall, including JDWR-B; the two biotypes of weedy rice belong to indica, JDWR-A was most related to JDWR-C, the dwarf type of weedy rice was distantly related to the tall type, and closely related to indica male sterile line Zhenshan 97A. The competition test between weedy rice and cultivated rice indicated that the dwarf type of weedy rice more significantly influenced on yield factors of cultivated rice.关键词
