A new paddy rice variety 'Donpishari' was developed by Iwate Agricultural Research Center in 2005. The variety was selected from the cross between 'Iwanan 7' and 'Fukei 179' conducted at ex-Kennan branch of Iwate Prefectural Agricultural Experiment Station in 1996. 'Donpishari' was intended as a middle-maturing variety with cold weather tolerance, high lodging resistance, high panicle blast field resistance and good eating quality. 'Donpishari' has been tested as a local line number 'Iwate 68' since 2001. It was adopted as a recommended rice variety of Iwate prefecture in 2005. Characteristics of 'Donpishari' are as follows: (1) Belongs to the middle maturity group maturing earlier than 'Hitomebore' and slightly later than 'Akitakomachi'. (2) The plants are a particle panicle number type. Its culm length is slightly shorter than both those of 'Akitakomachi' and 'Hitomebore' and the panicle number is fewer than 'Akitakomachi' and 'Hitomebore'. (3) High tolerance to sterility caused by low temperatures at booting stage, superior to 'Akitakomachi' and the same as 'Hitomebore'. (4) High lodging resistance, stronger than both 'Akitakomachi' and 'Hitomebore'. (5) High panicle blast field resistance, stronger than both 'Akitakomachi' and 'Hitomebore'. (6) The eating quality is as good as 'Akitakomachi' and similar to 'Hitomebore'.
