水稻‘越光’品种的“前世今生”

“Past and Present”of‘Koshihikari’Rice Variety

‘越光’是一种短园粒水稻品种,自1953年在日本一开始推广种植,就是日本人最喜欢的大米。即使大面积推广种植50多年之后的现在,由于其米质优良和长期形成的消费口碑,也依然是日本水稻最大种植推广品种。为全面了解‘越光’品种育种过程和其特有的农艺性状以及控制有利性状基因组信息,我们以“Koshihikari:a premium short-grain ricecultivar-its expansion and breeding in Japan”文章为最主要参考文献并加以摘译,对其历史进行梳理,同时对当前中国优质稻育种提出了个人的思考。

‘Koshihikari’is a short-grain rice variety.It has been promoted in Japan since 1953 and is the favorite rice of Japanese.Even after more than 50 years of widespread planting,it is still the largest variety of rice planted and promoted in Japan due to its excellent rice quality and long-term consumer reputation.To fully understand the breeding process of‘Koshihikari’variety and its unique agronomic traits,and control the genomic information of favorable traits,we used the article“Koshihikari:a premium short-grain rice cultivar-its expansion and breeding in Japan”as the main reference for excerpts and translates,sorted out the history of the variety,and put forward thoughts on the current breeding of high-quality rice in China.
