    STUDES ON THE IRRADIATION GENETICS EFFECTS OF ACCELERATED ARGON-IONS ON THE QUANTITATIVE CHARACTERS OF RICE

      摘要
    • 摘要: 应用加速氩离子辐射水稻干种子,分析了M_2数量性状(抽穗日数、有效穗数、株高、穗长、穗着粒数、穗实粒数等)的遗传效应。结果表明,各性状的遗传力随吸收剂量的不同而有差异,各性状都在60～120Gy剂量范围内表现较高的遗传力。各性状的遗传变异系数也因处理剂量的不同而有变化,以吸收剂量60～120Gy范围能诱发奋性状较大的遗传变异。M_2各性状的相对遗传进度因吸收剂量的不同差异较大,但各性状都有一个适宜剂量范围。在各自的适宜剂量范围内,各性状能获得较大的遗传进展。

       

      Abstract: Air-dried rice seeds were irradiated with 400Mev/amu accelerated argon ion beam. The genetic effects of M2 quantitative characters were studied.The results showedthat the heritability (hb2 )of all studied characters changed with different absorbeddoses. The heritability (hb2 ) and G.C.V.of all studied traits were rather highin the M2 generation rice seeds treated with 40Ar ion beam in the dose range of 60-120Gy. The relative genetic advance of each trait varied greatly with various dose treatments. Every trait could gain considerable genetic advance within the range of its appropriate absorbed doses.
