摘要：

以芝麻栽培种‘中芝14’（2n=26）为母本，分别与野生种‘刚果野芝麻’（2n=64）和‘野芝1号’（2n=64）进行正反交，结果表明：栽培种与野生种杂交均可得种子，其中‘中芝14’与‘刚果野芝麻’正交结籽率为2.16%，平均每蒴粒数为0.85粒，反交结籽率为95.14%，平均每蒴粒数为2.16粒；‘中芝14’与‘野芝1号’正交结籽率为8.21%，平均每蒴粒数0.51粒，反交结籽率为0.79%，平均每蒴粒数5.43粒。将杂种F1植株与亲本比较发现，F1植株的形态偏向于母本。因此，通过人工杂交的方法难以得到真正的杂交种。

Abstract:

Two cross between sesame cultivars ‘Zhongzhi 14’ and its wild species ‘Gangguo’ and ‘Yezhi 1’ were studied. The results indicated that: we could obtain a few of seeds. The seedy ratio between ‘Zhongzhi 14’ and ‘Gangguo’ was 2.16%, the average of seeds per capsule was 0.85 seeds. The seedy ratio between ‘Gangguo’ and ‘Zhongzhi 14’ was 95.14%, the average of seeds per capsule was 2.16 seeds. In addition, the seedy ratio between ‘Zhongzhi 14’ and ‘Yezhi 1’ was 8.21%, the average of seeds per capsule was 0.51 seeds. The seedy ratio between ‘Yezhi 1’ and ‘Zhongzhi 14’ was 0.79%, the average of seeds per capsule was 5.43 seeds. Then planted F1 next year, and compared F1 with their parents, we could found that the configuration of F1 was almost the same as their mothers. So it was difficult to obtain true hybrid seed using artificial hybridization method.
