A PRELIMINARY STUDY OF THE EARLY-RIPE WINGED BEAN "833

1 . In South China we collected a number of winged bean cultivars for trial planting in Guangzhou, they all belong to short-day types and flowered after August.2 . In 1983, we selected a early-ripe winged bean "833" from the variety "H45" which was introduced from Australia. The early-ripe winged bean flowered 63 days earlier than "H45". Seeds of the winged bean "833" were sown in Guangzhou, Nanking, and Beijing, they all flowered in summer after sowing 60, 64, 84 days respesti-vely and all normally riped.3 . The early-ripe winged bean "833" is possibly the neutralday and tempereture sensible type. It will grow well more northward than Beijing when raised seedling in greenhouse.4 . The winged bean "833" is the highly nitrogen fixative crop of rich protein, all parts of it are edible.
