三系杂交稻质核及质核互作遗传效应的估计法

THE METHOD OF ESTIMATING THE GENETIC EFFECTS OF CYTOPLASM、NUCLEUS AND NUCLEO-CYTOPLASMIC INTERACTION IN THREE-LINE HYBRID RICE

本文建立了一套以细胞质、细胞核及质核互作等遗传效应为参数的世代表型平均值遗传模型。提出了准确估计细胞质、细胞核及质核互作等遗传效应的方法,为正确评价不同质源,不同不育系的利用价值和开发前景以及为进一步了解不育细胞质对杂种F_1代主要经济性状的作用大小提供了一条有效的途径。

A set of genetic models for the phenotypic means of the generations, Including the genetic effects of cytoplasm, nueleus and nucleo-cyto plastoic interaction served as the parameters, have been established. And new method of estimating those genetic effects have been developed by designing a series of crosses. This method is helpful to the proper estimation of the practical values of the male sterile lines of various rice male-sterile cytoplasm resoures and to the further study about how the male sterile cytopasms affect the main characters in hybrid F_1.
