摘 要 ：采用含有化学诱变剂EMS的石蜡油，直接处理玉米自交系黄早4和7922的成熟花粉，并结合M2代突变基因的等位性测验，对花粉化学诱变创造特用玉米进行了研究。结果表明，在不同EMS处理浓度下，白色胚乳基因贝的诱变率平均为35.22‰,最高达到150.38‰, 1.67×10-3可作为EMS诱发y1基因突变的参考浓度。糖胚乳基因sul,孺胚乳基因wx1

Abstract:The quick development of speciality corn was carried out by direct treating mature pollen of corn inbred Huangzao 4 and 7922 with ethyl methanesulfonate in paraffin oil. Allele tests of M2 mutated genes were made with the existed speciality corn kernel genes. The results showed that the induced muta
