摘要：

以4个不同的六倍体裸燕麦品种和普通小麦进行正反杂交，确定裸燕麦和普通小麦的可交配性。调查杂种结实率并诱导杂种愈伤组织。结果表明：六倍体裸燕麦与普通小麦的可交配性和愈伤组织诱导率因品种和正反交方式的不同而不同。在以六倍体裸燕麦为母本的正交试验中，‘白燕2号’母本结实率最高，为12.98%。在以六倍体裸燕麦为父本的反交试验中，‘白燕5号’为父本时结实率最高，为6.25%。相同品种间正反交结实率也有差异。4个裸燕麦品种与春小麦的杂种胚均有较高的愈伤组织诱导率。此研究对燕麦的优异基因资源的利用和裸燕麦、小麦种质创新具有重要的理论和现实意义。

Abstract:

Distant hybridization between four kinds of Avena nuda L. and T. aestivum were conducted by reciprocal mating modes. Crossability between hexaploid Avena nuda L. and T. Aestivum was studied. Hybrid seed set ratios were investigated. Hybrid was inducted callus. The results showed that: different varieties and different mating modes made difference in crossability between hexaploid Avena nuda L. and T. Aestivum. Seed set ratios of ‘Baiyan2’ hybrids were the highest among all hybrids by ‘Baiyan2’ as female and T. Aestivum as male. That was 12.98%. Seed set ratios of ‘Baiyan5’ hybrids were the highest among all hybrids by ‘Baiyan5’ as male and T. Aestivum as female. That was 6.25%. Seed set ratios between the same parents were different with different mating modes. Rates of calli induced of all hybrids were high.
