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.
