摘要
A comparative study was conducted on four mulberry（ Morus alba） varieties（ lines） in Hunan dry land from the aspects of production performance,nutritional composition and amino acids content. The result showed that the four mulberry varieties all adjusted well to soil,climate and other natural conditions in Hunan province,presenting good growth. The dry matter content of four varieties（ lines） was above 25% and the crude protein content was more than 22%. Although the crude protein and total amino acid content of four mulberry varieties were lower than that of soybean powder,the proportion of various amino acids tended to be consistent,so mulberry leaf was very comprehensive in nutrition as an animal feed. Yuesang 11 had the highest fresh yield and crude protein of 14. 28 t / hm^2 and23. 22% respectively; Guisangyou 12 had the highest total amino acid content of 19. 58%. There were differences among four varieties,but each variety had its own advantages,so they all had good popularization value.
