Regarding the black-seeded soybean ‘Tambaguro’ for Edamame (green soybean) cv. ‘Murasakizukin 3’ and ‘Murasakizukin 2’ in Kyoto prefecture, it was requested to increase the seeding fields in Kyoto Prefecture due to the lack of seeds. Therefore, in order to gain basic knowledge of seed cultivation in the prefecture, we tried to produce stable seeds with a high germination rate in multiple fields, mainly in the central and northern regions of Kyoto Prefecture. In the case of ‘Murasakizukin 3’, it was suggested from the results of regional trial fields suggested that the combination of late sowing, white-surface black-underside multi and dense planting can contribute to increase of seeds yield of higher germination rate more than the standard value of 75%. On the other hand, it was speculated that the optimum sowing time for seed production of ‘Murasakizukin 2’ would be middle-late July because the germination rate of the obtained grains was higher than 75% of standard value.
