大蒜辐射育种,在芽内锈发的突变,属体细胞变异,具变异表现,不同于已知的生殖细胞突变型,其选育方法亦与之不同。本文总结75—80年六个 M_1代的田间表现性状对M_1的生理与生育特性及 M_1的突变性状与选择方法进行探讨。 Garlic radiation breeding, rust in bud bud mutation, is a somatic mutation, with variation, different from the known germ cell mutant, its breeding methods are different. This paper summarized the field performance traits of six M_1 generations in 75-80 years on the physiological and reproductive characteristics of M_1 and the mutation traits and selection methods of M_1.
