'Kanta' is a new, late maturing cultivar of Japanese pear (Pyrus pyrifolia Nakai) that was released in 2013 by the Institute of Fruit Tree and Tea Science (NIFTS), National Agriculture and Food Research Organization. The cultivar originated from a cross between 'Oushuu' and 'Akizuki' in1998, was selected as a promising tree in 2006, and subjected to the 8th National Trial (conducted at 34 experimental stations in 33 prefectures in Japan) as 'Nashi Tukuba 58' beginning in 2007. The cultivar was ultimately selected and released as 'Kanta' in 2013 and was registered as No. 23913 under the Plant Variety Protection and Seed Act of Japan on March 3, 2015. 'Kanta' trees are vigorous and produce many fruit spurs and moderately many to many axillary flower buds when grown at NIFTS in Tsukuba. The tree blooms at the end of April, later than 'Niitaka', and ripens at the beginning of October at nearly the same time as 'Niitaka'. The yield of 'Kanta' from young trees was equal to or higher than that of 'Niitaka'. 'Kanta' is resistant to black spot and has no serious susceptibilities to diseases or insect pests when trees are subjected to standard spraying program. The fruit of 'Kanta' are yellowish brown in color, are broad elliptical in shape, and the uniformity of the fruit is moderately good. Fruit weight averaged 554 g in the 8sup(th) National Trial, smaller than that of 'Niitaka'. The flesh hardness of 'Kanta' was 4.5 lbs, softer than that of 'Niitaka'. The soluble solids content and the fruit juice pH of 'Kanta' averaged 14.3% and 4.9, respectively in the 8sup(th) National Trial. The soluble solids content was higher than that of 'Niitaka', whereas the pH was lower than that of 'Niitaka'. The eating quality of 'Kanta' was judged to be better than 'Niitaka'.
