Abstract
At every month from April to August, we have sownd 12 wild Tsurumame strains (Glicine gracilis) which were gathered from various districts in Japan and were selected and bred for 4 years at the field of Nasu Experiment Station. Some characteristics of them were investigated. 1) All these strains show autumn growing habit but have pretty different grades among strains. Because these stems grow till late autumn, they are considered usefull as Forage crop. 2) They are distributed every-where from Tohoku district to Kyushu district, especially the flowering-habits of some strains in Kyushu are more delayed than the others. 3) As a soiling crop they have practically extended sowing period from April to June.
