摘　　要：为利用野生桑选育果用桑品种提供依据,对22个野生桑材料的物候期、果实经济性状和理化性状进行了研究。结果表明:22个野生桑材料中属早熟果的有12个、中熟果3个、晚熟果7个;单果重1.62~2.58g,米条挂果数38~64个,米条产果量75.25~141.9g,单株产果量0.69~1.53kg;果实还原糖含量10.92%~15.36%,总糖含量14.27%~18.12%,总酸含量0.15%~0.40%,VC含量6.92~9.33mg/100g,可溶性固形物含量16.47%~22.40%。22个野生桑的果实均未感桑椹菌核病,是优异的果桑品种材料。The phenological period, sorosis economic traits and sorosis physical and chemical properties of 22 wild mulberry materials were studied to provide the scientific basis for utilization of wild sorosis mulberry varieties. Result： There are 12 materials with early maturity, 3 materials with medium maturity and 7 late maturity in 22 wild mulberry materials. The single sorosis weight, sorosis number/ branch · m, sorosis yield /branch · m, sorosis yield/plant, reducing sugar content, total sugar content, total acid content, Vccontent and soluble solids content of 22 wild mulberry materials are 1.62 2.58 g, 38 64, 75.25 141. 9 g, 0. 69 -1. 53 kg, 10. 92% - 15. 36% ,14. 27% - 18. 12% , 0. 15% -0. 40% , 6.92- 9.33 mg/100g and 16.47%- 22. 40% respectively and 22 wild mulberry materials all do not infect sorosis sclerotiniose, which indicates that 22 tested mulberry materials are excellent sorosis mulberry materials.
