Baaed on the weak Noether symmetry proposed by Mei F X,this paper discusses the weak Noether symmetry for nonholonomic system of non-Chetaev type,and presents expressions of three kinds of conserved quantities by weak Noether symmetry.Finally,the application of this new results is showed by a practical example.

在我国,棉花是重要的经济作物,同时也是重要的战略物质。现在育种的主要目标是选育综合表现良好的新品种,要兼具高产、优质、抗病、抗虫等特性。新品种的选育离不开性状优良的种质资源,但是我国棉花遗传基础较狭窄,遗传多样性低。本研究从构建的黄河流域棉花综合群体中选育出37个优良种质系,评价黄河流域棉花综合群体衍生种质系的改良效果和遗传多样性,为长江流域棉花新品种选育提供优良种质资源。1.衍生种质系在产量和产
