Description
1. Seventy-one clonal strains of Kudzu, Pueraria hirsuta Matsum. were collected all over Japan in 1962 and were made research in their morphological characters and chemical contents as fodder.
2. Strains tested were classified into three types, -, ± and +, with respect to the shapes of folioles. (Plate I)
And the hairless type especially on stems and petioles were found though in small numbers. (Plate II and III)
3. Chemical analysis of leaves of 6 strains carried out in October proved that the amounts of crude proteins varied from 12 to 20 %, crude fats from 27 to 4.9 %, but not so much differences were found in crude fibers.
4. The distribution of the hairless type, newly found in our collection, were investigated by means of sending inquiries throughout the country. Judging from the investigations on 292 places, the existence of this type was revealed in 12 % of them, and main distribution was found to be located along the coast of Japan Sea.
