| 摘 要： | γ射线辐照优良的杂交组合是提高诱变效率的基础;杂种比品种具有较高的辐射的敏感性;辐照杂种早期世代可以提高诱变效率,辐照杂交当代,使辐射世代与杂交世代同步,有利于各世代的选育,育种效果最好;辐照杂种后代的性状分离稳定进程与杂种杂合程度有关。研究表明,辐射与杂交结合是提高辐射育种效果的有效途径之一。

| Abstract: | During the period of 1973—1978,dry wheat seeds of early genera-tion hybrids and their parent varieties were irradiated by 60Co-γ raywith a dosage of 25KR.In this paper some general remarks were madeon the radiosensitirity and mutation rate of the varieties and hybridsunder treatment.Thu |
