用γ射线照射“桂朝二号”种子,引起性状发生微突变的频率比大突变的高。突变体株高,千粒重的世代遗传力和γ_3所具有的广义遗传力较高;单株穗数与单株产量的遗
Irradiation of seeds of “Gui Cha II” by γ-ray caused the micro-mutation of the trait to occur more frequently than the large mutation. Mutant plant height, 1000-grain-weight heritability and γ_3 have a higher heritability of generalized heritability; the number of panicle per plant and the yield per plant
