A new rapeseed [Brassica napus L.] cultivar, "Kitanokirameki", was developed at the NARO Tohoku Agricultural Research Center in 2011. This cultivar was selected from the progenies of the cross between "Kizakinonatane" and "Onyx", with a goal of developing a high-yield cultivar free from erucic acid and adaptable to Hokkaido and the Tohoku region in Japan. The seeds of this cultivar are free from erucic acid, similar to the seeds of "Kizakinonatane". This cultivar matures slightly later than "Kizakinonatane" and has high wintering ability. At Morioka, Iwate, the index of cold and snow damage to this cultivar was lower than that of "Kizakinonatane". At Memuro, Hokkaido, the ratio of over-winter survival of this cultivar was higher than that of "Kizakinonatane" ; therefore, the yield of this cultivar was more than that of "Kizakinonatane". These data suggest that "Kitanokirameki" is adaptable to the Tokachi district at Hokkaido. This cultivar will help gain stable and high yield production and expansion of the production area in the Tokachi district.
