| Research Abstract |
It was confirmed that irregularly chromosome behavior concerned with abnormal growth of embryo sac and zygote in triproid cultivar'Kiyo'. It is suggested that the abnormalities of embryo sac and zygote growth induced by hetroploidy lead to the poor fruit set of'Kiyo'. The low quality fruit'Ajinashika' was lower in sucrose and sorbitol accumulations than the normal fruit, indicating that expression of sugar metabolic genes, not hetroploidy, was concerned.
