In order to explore QTLs related to kernel length and 1 000-grain mass,wheat variety‘Xinong 981'and‘Shaanmai 159'were used to develop 169 F_2 population and F_(2:3)lines.The F_2 population was exploited to construct genetic map and the F_(2:3)lines grown in two different environments of Yangling and Sanyuan for testing the phenotypic data.The results showed that highly significant difference of environment variance was detected for kernel length and 1 000-grain mass.Thirty-one related QTLs were detected in ...

小麦是世界三大主粮之一,其产量直接关系着粮食安全问题,因此,寻找控制小麦产量性状的基因,提高小麦产量一直是科研工作者的目标。千粒质量是小麦产量的三大主要组成因素之一,对小麦的产量具有极其重要的影响,而籽粒的大小及形态则直接影响着千粒质量的大小[1],粒长(kernel len
