'Mikuri' originated from a cross between 'Ishizuchi' and 'Shuuhou' in 1995. 'Mikuri' was selected in 1999 and subjected to the 6th National Trial on Chestnuts as Kuri Tsukuba 39 beginning in 2000. The trials were conducted at 13 experimental stations in 12 prefectures in Japan. 'Mikuri' was registered as No. 20474 under the Plant Variety Protection and Seed Act of Japan on March 9, 2011. The tree is vigorous with an upright form. The full bloom date of female flowers is early June, later than that for 'Tsukuba', and at the same time as that for 'Ishizuchi'. 'Mikuri' ripens around late September to early October, in between 'Tsukuba' and 'Ishizuchi' chestnuts. The yield of 5-9 year old trees is as high as those in 'Tsukuba' and 'Ishizuchi'. The incidences of polyembryony of the nut, pericarp bursting, and decayed nuts in 'Mikuri' are very low and are comparable to those traits in 'Ishizuchi'. Infestation by nut insects occurs frequently as in 'Tsukuba' and 'Ishizuchi'. The 'Mikuri' nut is round in shape and weighs about 26 g on average, larger than 'Ishizuchi' nuts in the National Trial. The specific gravity of 'Mikuri' nuts is higher than the specific gravity of 'Tsukuba' and 'Ishizuchi' nuts. The kernels of 'Mikuri' are yellow in color, rich in sweetness and flavor, mealy in texture, and of good eating quality. The pellicle is difficult to peel, as are the peels of 'Tsukuba' and 'Ishizuchi' chestnuts.}, pages = {1--9}, title = {ニホングリ新品種 '美玖里'}, volume = {19}, year = {2015}, yomi = {サイトウ, トシヒロ and コトブキ, カズオ and サワムラ, ユタカ and タカダ, ノリオ and ヒラバヤシ, トシロウ and サトウ, アキヒコ and ショウダ, モリユキ and テライ, オサム and ニシバタ, トヨヒデ and カシムラ, ヨシキ and アベ, カズユキ and ニシオ, ソウゴ and キハラ, タケシ and スズキ, カツユキ and ウチダ, マコト} }
