Plant Genetics and Breeding Laboratory Kazuhiro NEMOTO Assistant Professor Plant genetic resources, Evaluation and genetic improvement of minor crops, Conservation genetics, Gain amaranths, Seed system In the world, there are many useful crops to solve the problem of food and nutrition in developing countries, to enrich our life, even though it is still minor or underutilized crop. We are focusing these crops. Genetic improvement and molecular analysis of grain amaranths is now our major research topics. Field works through national and international research is also important for our Lab. Theme1 Genetic improvement and molecular analysis of grain amaranths including under utilized crops A B C D A B C 写真、図 Grain amaranths are one of our target crops. We have revealed their genetic diversity, phylogenetic relationships, molecular analysis of GBSS genes etc. 写真、図 From the field study, we can find new challenges. Upper left: Burukina Faso, Lower left: Nepal, right: Nagano, Japan Theme2 Conservation genetics of local varieties; now we are focusing on Brassica vegetables such as turnip and radish using S haplotypes. Theme3 Evaluation and characterization of plant genetic resources/ Bioresource Science Division Crop Science Laboratory The Crop Science Laboratory seeks improved production technologies for crop plants. Coping with global environmental change, reducing environmental load and efficiently using finite resources in crop production are important topics in crop science. Toward the improved sustainability and stability of food crop production for rice, soybean and common buckwheat, we aim at establishing cultivation technologies that strike a balance between reduced input of energy and other finite resources such as chemical fertilizers and sustained high levels of yield and quality. Improving the growth of crop plants under unfavorable soil conditions, ranging from arid to humid, is also an active area of investigation. Low-input cultivation and improved palatability of paddy rice A B C D A B C Culture test on fertilizer effect on rice (left), non-contact measurement of flower-bud temperature of common buckwheat (middle) and germination test of soybean under excess water condition (right) Field survey may be employed as needed (left) Microscopic morphology of soybean seed in regard to germination growth under excess soil moisture (right) Improved submergence tolerance in soybean Improved yield and quality of buckwheat through control of soil water conditions Bioresource Science Division Motoyuki HAGIWARA Professor Aiming to enhance growth and yield of crops under unfavorable or low-input conditions necessary for improved and stabilized food production Keywords; rice, soybean, buckwheat, low-input cultivation, water stress 18
