| Abstract: |
| In order to provide references to the research of water use efficiency, 17 spring wheat lines were grown in Yinchuan site in 2007. The phenotypic correlation and genetic correlation analysis based on the remarkable generation variance analysis and simple correlation were carried on. The results showed that genotypes are significant different. Relationship between △Gm and △Sm, WUE, maL, Ci, Gs and Ci/Ca are extremely positively genetic correlated，but with Pn in flowering stage and Tl in filling stage are significantly negatively correlated respectively; △Sm is extremely positively genetic correlated with WUE, maL, Ci, Gs, Ci/Ca in flowering stage, while negatively genetic correlated with Tl and Pn in flowering stage. At last it demonstrates the relationship between △ and WUE, ash content and so on, and it concludes that a good genetic correlations among relevant traits and △。 |
