摘　　要：采用杂交方法育成早生桑品种育151、育237,具有发芽早、产叶量高,叶质较优、抗黄化型萎缩病较强等特性,发芽期比早青桑捉早2-3天.比湖桑32号早8天左右.产叶量提高6-41%.Two early sprouting mulberry varieties, 'Yu-151' and 'Yu-237' were bred through hybridization. Their charcteristics arc early budding, high leaf yield, better leaf quality and relatively resistant to the mulberry dwarf disease. Their budding date are 2-3 days earlier than 'Zaoqingsang* and around 8 days earlier than 'Husang-32'. Their leaf yields increased by 6-41% over the control variety 'Zaogingsang'. And these two new varieties arc intended to be put into production as early sprouting mulberry varieties.
