摘  要:
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.
