The cultivar was developed from a cross between ‘Chikusui’ and Tsukuba 43 in 1993, selected as a promising tree in 2006, and subjected to the eighth national trial as Nashi Tsukuba 54 from 2007, at 38 experimental stations in 37 prefectures throughout Japan. The cultivar was released as ‘Hatsumaru’ in 2014 and was registered under the Plant Variety Protection and Seed Act of Japan on June 19, 2015 (Registration No. 24374). ‘Hatsumaru’ trees are medium to moderately vigorous. They produced medium to moderately high number of shoots, few to medium number of fruit spurs, and medium number of axillary flower buds in the national trial. Flowering time was approximately April 15, three days earlier than that of ‘Chikusui’ and ‘Kosui’, and the harvest time was approximately July 30, which was one week earlier than that of ‘Chikusui’ and three weeks earlier than that of ‘Kosui’. ‘Hatsumaru’ fruits ripened until the first half of August, when the demand for Japanese pear peaks in consumer areas and the favorable sales are possible, in most of the pear-producing areas in Japan in the national trial. The cultivar was resistant to black spot and there was no serious problem of diseases and insect pests under standard spraying program. ‘Hatsumaru’ is cross compatible with other leading cultivars as its S-genotype is S1S4. The fruit shape of ‘Hatsumaru’ is oblate to round. Fruit weight averaged 296 g in the national trial, smaller than that of　‘Chikusui’ and ‘Kosui’. The flesh firmness of ‘Hatsumaru’ was 4.1 lbs, softer than that of ‘Chikusui’ and ‘Kosui’. The soluble solid content was, on an average, 12.4%, which was lower than that of ‘Chikusui’ and ‘Kosui’. The pH of fruit juice, on an average, was 5.1, which was comparable with that of ‘Chikusui’ and lower than that of ‘Kosui’. The eating quality of ‘Hatsumaru’ was comparable with ‘Chikusui’ and ‘Kosui’. The shelf-life of ‘Hatsumaru' was around 5 days, a little shorter than that of ‘Kosui’. The dead lateral flower bud rate of ‘Hatsumaru’ in Kumamoto Prefecture was apparently higher than that of ‘Kosui’. ‘Hatsumaru’ is expected to be extensively cultivated as a very-early ripening cultivar in Japan, especially in Kanto and South Tohoku region.\n
