摘要
利用与苯达松敏感致死基因 (ben )紧密连锁的 SCAR标记 ,对田间以农林 8号 m为 ben基因供体转育的后代进行了 PCR检测。利用该标记不仅能鉴别出转育的材料是否含有 ben基因 ,而且能区别它是含 ben基因的纯合体还是杂合体 ,从而有效地指导田间选育 。
With rice cultivar Norin 8m susceptible to bentazon as donor of ben gene, SCARs tightly linked to ben were utilized for selection of ben. Results showed that homozygous and heterozygous genotypes with ben could be identified with the SCARs. The molecular markers offered a powerful tool for indirect selection of ben and could accelerate the introgression of ben into current rice cultivars.
