从87(341)的培育成功分析硬粒小麦品质性状的选择研究

Quality select in durum wheat breeding

根据通心面的商品外观、加工品质和蒸煮品质对硬粒小麦原料提出的主要品质要求，在优质硬粒小麦８７（３４１）品系的选育过程中，品质性状的选择以蛋白质、面筋和黄色素为主。Ｆ３代面筋的质量、含量和黄色素含量的分离相当大，为不错失优质品系，应从Ｆ３代起就开始分析。Ｆ４代在农艺性状选择的基础上，为品质测试和品质上择优汰劣的关键世代。Ｆ５代及其后代的选择则继续兼顾产量和品质指标。

According to require of macaroni products to raw material,quality breeding on durum wheat is carry through.On the basis of quality data including protein content,wet gluten content and quality,carotenoid pigment content and yellow kernel percentage and so on.It is important to select high quality breeding line from low generation to high generation.Breeding course of high quality durum wheat 87(341) variety indicates:Gluten and carotenoid pigment of F 3 have separated intensity,pick out should start from this generation,selection of offspring should give attention to yield and quality.
