摘　　要：以鲁桑系二倍体湘7920为母本,以化学诱导广东桑组合塘10×伦109获得的四倍体诱59为父本,采用杂交育种的方法育成了人工三倍体桑树新品种湘桑6号(2n=3x=42)。该品种具有丰产优质的特点:桑叶产量比对照湖桑32号提高30.8%;养蚕试验万蚕茧层量提高6.2%,100 kg桑叶产茧量提高6.5%,单蛾良卵数提高7.8%;桑叶干物粗蛋白的含量提高2.35%。Xiangsang 6（2n =3x =42） was bred by using Morus multicaulis L. Xiang 7920 2x as male parent and You 59 4x as female parent, which was induced from M. atropurpurea K. Tang 10 x Lun 109 with chemical mutagenesis. It is of high yield and hight quality. Compared with the control variety Husang 32, the leaf yield of Xiangsang 6 increased by 30.8% ; The cocoon shell yield per 10 000 larvae, cocoon yield of 100 kg mulberry leaves and good egg number per mother moth increased by 6.2%, 6.5% and 7.8%, respectively, When silkworms were fed on the leaves of the variety; The crude protein content of dried mulberry leaf increased by 2.35%.
