It originated from crossing '162-29' ('Niitaka'×'Housui') and 'Nashi Hiratsuka 17' ('Kumoi'×'Kousui'), in 1984. It was selected as a promising tree in 1991, and had been subjected to the 6th local adaptability test as 'Nashi Tsukuba 45', conducted at 39 experimental stations of 37 prefectures in Japan. It was designated and registered as Nashi Norin 20 on October 25, 2000, and also registered as No. 11120 under the Seeds and Seedlings Law of Japan on March 17, 2003. The tree vigor is intermediate and exhibits medium amount of fruit spurs, though a little more than 'Kousui'. It is cross compatible with 'Kousui', 'Housui' and 'Gold Nijisseiki'. It blooms at the same time as 'Kousui' in eastern Japan and 'Housui' in western Japan. It ripens between 'Kousui' and 'Housui'. It is practically resistant to any kind of diseases and insect pests under the standard spraying program. The fruit is round in shape. It weighs about 400g on an average, larger than 'Kousui' but not as large as 'Housui'. The fruit quality is excellent the same as 'Kousui' and 'Housui'. Many fruit retain calyx at maturity. Shelf life is as long as 'Housui', but longer than 'Kousui'.}, pages = {21--30}, title = {ニホンナシ新品種 'あきあかり'}, volume = {3}, year = {2004}, yomi = {コトブキ, カズオ and サイトウ, トシヒロ and マチダ, ユタカ and サトウ, ヨシヒコ and マスダ, リョウイチ and アベ, カズユキ and クリハラ, アキオ and オガタ, タツシ and テライ, オサム and ニシバタ, トヨヒデ and ショウダ, モリユキ and カシムラ, ヨシキ and コゾノ, テルオ and フクダ, ヒロユキ and キハラ, タケシ and スズキ, カツユキ} }
