The 6th Chestnut National Trial was conducted at 16 experiment stations from 2000 to 2008, using four chestnut selections, Kuri Tsukuba 36,37 ,38 and 39, selected from the 6th chestnut breeding program at the NARO Institute of Fruit Tree Science. Kuri Tsukuba 36 was designated as cultivar 'Porotan' because its pellicle is easy to peel and it has good eating quality. 'Porotan' was registered as No.15658 under the Seeds and Seedlings Law of Japan. Kuri Tsukuba 37 was judged to be unsuitable for cultivar designation because of a high ratio of polyembryony and insect damage. Kuri Tsukuba 38 was judged to be unsuitable for cultivar designation because of its high mortality rate. Kuri Tsukuba 39 was designated as cultivar 'Mikuri' because the kernel is yellowish-cream in color and it has good eating quality. 'Mikuri' was registered as No.20474 under the Plant Variety Protection and Seed Act of Japan.
