众所周知,电离辐射可诱导遗传变异,为有效选择提供机会。1955年Gregory曾观察到,花生辐射群体的遗传变异比对照高4倍,并指出,与对照群体相比,群体均数一般是不变化的,但并非一成不变。由于诱导数量性状变异已成为育种程序的一个辅助手段,本研究用γ It is well-known that ionizing radiation can induce genetic variation and provide opportunities for effective selection. In 1955, Gregory observed that the genetic variation of the irradiated population of peanut was four times higher than that of the control and noted that the population mean was generally constant but not constant in comparison to the control population. Due to the induction of quantitative trait variation has become an adjunct to breeding programs, this study used γ
