摘要
中生中熟桑树新品种强桑1、2号经区试鉴定,单位面积桑产叶量分别比对照种荷叶白增加37.60%和15.79%,分别极显著和显著高于对照;万头蚕产茧层量强桑1号比对照低0.50%,强桑2号比对照高1.67%;强桑1号对桑黄化型萎缩病抗性高于对照,而对桑疫病的抗性低于对照,强桑2号强抗桑黄化型萎缩病和桑疫病。两个品种生长势旺,农艺性状优良,适应性广。
Two new medium budding varieties of mulberry, QiangSang No. 1 and No. 2, were bred and passed through regional test. The yields of mulberry leaves per ha were increased by 37.60% and 15.79%, significantly higher than that of the control group ＂HeYeBai＂. The cocoon shell weight of 10000 silkworms fed with QiangSang No. 1 leaves was decreased by 0.50%, when fed with QiangSang No. 2 leaves increased by 1.67% than the control group. The resistance to yellow dwarf disease of QiangSang No. 1 was stronger, but the resistance to black bacterial blight was weaker than the controlled. Both of the resistances to yellow dwarf disease and black bacterial blight of QiangSang No. 2 were stronger than the control group. The two new mulberry varieties have some other characteristics better than the control, such as vigorous growth, better agronomic characteristics, and wide daptability.
