本文概述了几个花生品种对化学诱变的研究。硫酸二乙酯[(C_2H_5)_2SO_4=154·1a]对生理上较不敏感的品种可较高速度的诱向单一特性和多趋向性的突变。各巨型突变体是单方面的,一个是显性则其他都是隐性或半显性。在有些条件下可引出有多方面遗传型为背景的突变。生理敏感性的研究指出一个品种经常比其他品种对EMS(磺化乙基甲烷)、EB(乙基溴盐)、吖啶黄素、氯霉素、红霉素、5—BV(5—溴尿嘧啶),和MNNG(N—甲基—N~2—硝化—亚硝基胍)等化学诱变剂的敏感性大些。本文也讨论了 长时间化学诱变剂处理对花生细胞核和胞质突变诱导的作用。
This article outlines several studies on chemical mutagenesis of peanut varieties. Diethyl sulfate [(C_2H_5) _2SO_4 = 154 · 1a] can induce uni-directional and multi-tropic mutations at higher rates for physiologically less sensitive species. Each giant mutant is unilateral, one is dominant while others are implicit or semi-dominant. Under some conditions, there are many mutations in the genetic background. Physiological sensitivity studies indicate that one variety is often more susceptible to EMS (sulfoethylmethane), EB (ethyl bromide), acriflavine, chloramphenicol, erythromycin, 5-bromo Uracil), and MNNG (N-methyl-N ~ 2-nitration - nitrosoguanidine) and other chemical mutagens more susceptible. This article also discusses the effects of long-term chemical mutagen treatment on the induction of peanut nuclear and cytoplasmic mutations.
