The 5th local adaptability test of chestnut was conducted for five strains which had been selected in the 5th primarily chestnut breeding program at Tsukuba in 1984. The selected strains were 'Tsukuba 31', 'Tsukuba 32', 'Tsukuba 33', 'Tsukuba 34' and 'Tsukuba 35'. The test was carried out from 1991 to 2000 at 18 locations in 17 prefectures in Japan. Although all the selections were excellent in eating quality, four of five strains were suffered unfavorable fruit characters, such as small fruit size, polyembryony and splitting of pericarp. Only 'Tsukuba 35' was recommended as a new cultivar.
