| Abstract: | It is suggested that homozygosis had happened in gamete during hybrid zygote development process through the study on early generation stability in rice. Cytology evidence should be discovered from studying gamete development. The results showde that the embryonic developement was basically normal in observing gamete emtryonic; the phenomenon of chromosome osmotic and meiosis were not been observed. And further study should be more on the early generation stability in rice and cytological study. |
