摘要
对大豆^(60)Co-γ射线辐射高代表现及其与相关关系的研究结果表明:大豆产量的遗传率虽较低,但它与生育期、株高、结荚期长短,具有密切相关,且茎粗的遗传率高,易于早代稳定。从而表明,茎粗在早代选择的有效性,为大豆辐射后代的早期选择,提供了可靠的依据。
Investigation has shown that the yield of soybean,though its heritability is quite low,is closely related to the growing period,the plant height,and the length of pad- setting time.Besides,the heritability of stem thickness is high and tends to be stable in the early generations.It is concluded that character selection of stem thickness should be undergone in the early generations,which will ensure the reliability of early selection by radiation breeding.
