| Outline of Final Research Achievements |
Yam is major staple food in West Africa, South Pacific islands or Caribbean islands, while in Japan or Southeast Asia yam is popular as a vegetable or processed foods. Planting materials of yam is tuber setts or whole tubers. But the multiplication rate is low compared with cereals so that it is difficult to rapidly increase production of yam if farmers want to expand planting area.
Appropriate culture condition for vine cutting of yam was cleared. For vine cutting, shoot formation will be enhanced under long day length. Depend on medium and varieties, the growth of vine cutting were varied. Mechanized vine propagation was verified for seed tuber production of yam. Comparing the growth of plants from vine cutting and mini-setts was carried out under same growth condition with manipulation of dormancy of tuber and growth of seedling. Both plants within each variety showed similar growth. This result showed plant from vine cutting can use for evaluation of varieties under yam breeding.
