摘要： 小麦品质育种不仅要注意提高蛋白质含量，更应大力改进小麦面筋的质量。利用诱发突变手段可以获得营养品质和加工品质优良的新品种，如晋麦23号、晋麦22号和原A14等。能否充分发挥育成品种的优质性状，取决于相应的生态条件和栽培水平是否适宜。诱发突变品质育种成败的关键在于试材与亲本的选择。亲本中要具有高蛋白遗传基础和稳定的品质性状，并要克服亲缘单一化和不利基因的干拢。产量与品质的矛盾，可以通过诱发突变与杂交相结合的方式，加以缩小或取得一定程度的协调。

Abstract: In wheat puality improvement breeding,more attention should be paid to improving the content and quality of gluten than to improving the content of protein.By means of induced mutation,it is possible to obtain new varieties superior is both nutritional quality and processing quality such as Ji n mxi 23,Jinmai 22 and Yuaa 14,etc.Whether the fine characters of developed varieties can be fully displayed depends on the proper ecological conditions and the cultivation level.The key factor for the success in quality breeding by means of induced mutation lies is the test material and the selection of parents.The parents must possess 6ig6 protein genetic base and stable quality characters and can overcome the shortcoming of too simplified blood relationship and.the iatecfereace of unfavorable genes.As for the contradiction between yield and quality,it can be ceduced or compromised to a cerrain degree through proper combination of induced mutation and hybridization.
