| 摘 要： | 远缘杂交是遗传和育种研究的一个重要内容,它首先遇到的问题是杂交不易成功,杂种后代不育,总称“结实性”问题。本文主要是介绍小麦与黑麦类远缘杂交中,当代结实率和杂种结实性两方面的研究结果,特别是不同亲本类型以及正、反交对结实性的显著影响。

| Abstract: | The magnitude of crossability varied with type of crossing.Whenoctaploid Tritical was crossed as female parent with wheat the rate ofseed setting was lower than the reciprocal cross,but the seeds were moreplump and heavier in test weight,thus assuming better quality for ger-mination.when hexaploid T |
