γ射线辐照野生稻与黑糯F_1植株的诱变效应研究

MUTANT INDUCING EFFECT OF γ RAY IRRADIATION FOR HYBRID RICE F 1 DERIVED FROM CROSS OF BLACK GLUTINUS RICE×WILD RICE

辐照黑糯×野生稻Ｆ１植株孕穗期的诱变结果表明：辐射后代通过选择和回交，获得矮秆、耐冷和高产的黑糯品系。现实遗传变异力分析表明，选择对颖壳颜色、黑糯、黑籼都有效，对白籼和结实率无效。

The hybrid rice F 1 plant derived from the back crossing of glutinus rice × wild rice was irradiated with γ ray.The result of investigation to the induced mutant showed that through the selection and backcross,a black glutinus rice strain with the short stem,cold tolerance and high yield was developed.The analysis of the ability of heredity variance showed that the selection was effective for the husk colour, black glutinus and black indica rice,but ineffective for the white indica rice and seed setting.
