| 摘 要： | 目前小麦育种中普遍存在的问题是种质资源匮乏,改变这种现状最基本、有效的途径之一,是应用理化诱变剂进行诱变育种,即人工诱导产生突变经多代筛选和鉴定,培育高产、优质及综合性状优良的小麦新种质。EMS是一种良好的化学诱变剂,目前已成为在作物诱变育种中应用最广泛、应用效果最好的一种化学变剂。本研究利用不同浓度EMS对小麦品种新春11号籽粒进行诱变处理,确定EMS适宜诱变剂量,并探讨EMS对小麦产量性状和农艺性状的诱变效应。

| Abstract: | The present common problems in wheat breeding is germplasm resources scarce.A way of change this operation is mutation breeding,which is combination of conventional breeding and molecular breeding.There were mutations by artificial induction,New wheat germplasm was selected in the following generations and identification,breeding high yield,high quality and excellent comprehensive characters of wheat new germplasm.Ethyl methyl sulfomar(EMS) is a favorable chemical mutagen,and it has become one of the most w... |
