Our life depends on bioresources from agriculture, forestry and fisheries for a long time. Especially food crops and industrial crops are very important for quality life. We continue the researches on their growth habits, flowering and fruiting characteristics, yield, quality and utilization. We also try to develop sustainable and stable high yield culture systems and to modify cultural varieties. The target crops are rice plant, soybean, sweet potato and Iseimo (Chinese yam) etc.. Our laboratory contribute to promote crop production in Mie area.
