摘　　要：通过对 4个二倍体野生桑、4个六倍体野生桑材料以及 4个二倍体栽培桑品种的叶质养蚕试验分析证明 :野生桑饲蚕的食下量、消化率、全茧量、茧层量等较低 ,茧层、茧重的转化率及生产效率均明显低于栽培种。因此 ,一般情况下不宜直接采野生桑叶饲蚕。对有良好农艺性状的野生桑 ,可定向培育良种化 ,使其发挥群体优势 ,为养蚕提供优质的饲料来源。Four diploid wild mulberry varieties, four hexaploid wild mulberry varieties and four diploid cultivated mulberry varieties were used to investigate their mulberry leaf quality for feeding silkworm. The results showed that the appetite, digestibility, weight of whole cocoon, number of cocoon layer, transform rate and production efficiency of cocoon weight of silkworms fed by the wild mulberry were lower than those by the cultivated mulberry. Therefore, the wild mulberry leaf should not be directly used to feed silkworms in the general case. The wild mulberry varieties with better agronomical characters may be improved to develop their population dominance and to provide silkworm industry with good quality feed resources.
