영문 초록

Inter-generic hybridizations were made among the species T. aestivum, T. durum, H. vulgare and S. cereale using 0.1% concentration of immunosuppressant EACA treatment, The results obtained were as follows; 1. In reciprocal T. aestivum x H. vulgare crosses no viable seed were obtained. The cross T. durum x H. vulgar gave 6 viable seeds. 2. The cross H. vulgare x S. cereale resulted in 9.2% of the, fertilized florets setting seed. However, none had a hybird embryo. The reciprocal gave a 0.12% seed set. 22 seeds were viable from the 31 seeds obtained from this cross. 3. T. aestivum x S. cereale cross resulted in 26.3% of the fertilized florets setting seed. In T. durum x S. cereale crosses, 10.6% of the fertilized florets set seed. 4. A differential response to a 0.1% concentration of EACA was observed. T. aestivum intergeneric crosses showed a 4.8% to a 6.0% higher seed set than did none treated plants. However, H. vulgare plants gave a low seed set than did the none treated plants.
