山西省冬小麦品种穗发芽抗性鉴定研究

对２３５个小麦品种（系）成熟期穗发芽抗性鉴定的研究结果表明，红粒品种普遍抗穗发芽，但不少白粒品种抗性亦较强，颖壳颜色与抗性无关，山西省育成品种（系）的抗性稍差于国外品种。从山西省的１５２份白粒品种中鉴定出８份较抗穗发芽的品种，以供育种及专题研究利用。

Studies on Appraisal of pre-harvest sprouting Resistance in Winter Wheat Resource of Shanxi Province

The resistance to pre-harvest sprouting of 235 winter wheat resources were studied.The results indicated that some of white-grained winter wheat varieties was also resistant to sprouting, although most red-graines wheat varieties were generally resistant. The colour of husk doesn't associate with resistance to sprouting. Winter wheat varieties Developed by shanxi province was poor on resistant to sprouting than one of foreign varieties. 8 varieties with more strong resistance have been appraised from 152 white-grained wheats of shanxi province and that provide the breeding and other specialized studes.
