摘 要 ：利用中国春-Cheyenne二体代换系及中国春缺体-四体、Ta₁中国舂、兰州黑麦等,对中国春可交配性基因的定位及与Ta₁的关系进行了研究。在中国春染色体2B、6D及7A上,第一次发现了可交配性基因kr存在,同时证明了Ta₁基因与kr基因不存在相互干挠。在北京条件下利于kr基因表达。

Abstract:The chromosomal locations of crossahility genes of Chinese Spring and relationship between the crossability genes and Tai-gu dominant male sterile gene Ta₁ were studied by using crosses between Chinese Spring-Cheyenne disomic substitution lines, nullitetra lines of homoeologous group 5 of Chinese Spring、Chinese Spring、Cheyenne、Ta₁ Chinese Spring and rye cultivar Lanzhou in environment of Beijing. For the first time, the results indicated that there were some crossability genes (kr) with rye in chromosome 2B、6D、7B in Chinese Spring, except crossability genes in chromosome 1A、5B、5A、5D、7D. The results also indicated that there was no interference between gene Ta₁ and crossability genes (kr). So they can independentlly express when they are in a plant. In the environment of Beijing, the kr genes express easily in Chinese Spring.
