高产一直是小麦育种的基本目标,近几年来国内各育种单位又相继提出了优质问题。蛋白质和赖氨酸含量是小麦营养品质的重要内容,国外从五十年代起就已发现蛋白质和赖氨酸含量有随产量水平提高而下降的趋势。因此,高产与优质能否统一,已成为小麦育种者普遍关心的问题。国外从七十年代起就有许多学者研究产量性状与品质的关系,因材料不同,所得结论差异甚大。小麦种质资源的产量与品质性状的关系无疑将对 High-yielding has always been the basic goal of wheat breeding. In recent years, all domestic breeding units have successively raised the quality problems. The content of protein and lysine is an important part of wheat nutritional quality. From the 1950s onward, the content of protein and lysine in China has been decreased with the increase of yield. Therefore, whether high yield and high quality can be unified has become a common concern of wheat breeders. Abroad from the seventies, many scholars have studied the relationship between yield traits and quality, due to different materials, the conclusions obtained vary greatly. The relationship between wheat germplasm yield and quality traits will undoubtedly be right
