摘要: 利用一套5个豌豆染色体易位系和2个形态标记基因系chl-7及Viola为标记材料, 对豌豆卷
曲突变基因curl进行了染色体定位。结果表明, 突变基因curl位于豌豆第3 染色体的长臂上, 处于黄化基因chl-7和种皮皱纹基因r 之间, 排列顺序为r-curl(chl-7) , curlchl-7之间的交换值为34. 24 %±4. 57%, 与r之间的交换值为19. 79 %±3. 55 %。

Abstract: A set of 5 chromosome translocation lines and two marker gene line chl-7 and Viola were used in testing the chromosome location of curl mutant gene in pea. The results indicated that mutant gene curl was located on the long arm of the chromosome 3 in pea, between the known yellow green leaf gene chl-7 and the rugose peri carp gene r, their order is r-curl (chl-7) . The interchange values of curl to chl-7 and r are 34. 24%±4. 57% and 19. 79%±3. 55% .
