To increase rice noodle production, rice  cultivars  with high amylose content and a heading trait that  differs from that of ‘Koshihikari’ are desirable. We developed an early maturing rice cultivar with high amylose content, which we named ‘Amichanmai’, from a cross between ‘Niigata 79’ (Koshinomenjiman), which produces slender grains with  high  amylose  content,  and a high-yielding line, ‘Hokuriku 191’. In 2013, we applied to have this new cultivar officially registered    by the Ministry of Agriculture, Forestry and Fishery.  The  heading  and  maturity  dates  of  ‘Amichanmai’ are
1 or 2 days later than those of ‘Akitakomachi’, and ‘Amichanmai’ rice can be harvested at least 1 week earlier than ‘Koshihikari’ rice. Moreover, ‘Amichanmai’ plants can grow in the southern region of Tohoku as  well as the southern and western areas. A comparison
between ‘Amichanmai’ and ‘Akitakomachi’ plants revealed similar culm and panicle lengths, but fewer ‘Amichanmai’ panicles. The ‘Amichanmai’ 1000-grain weight is almost 22 g, which is approximately 1 g less than that of ‘Akitakomachi’, but there are no major differences in grain yields. Additionally, the  semi-  round ‘Amichanmai’ rice grain varies from the shape    of the parent ‘Niigata 79’ grain, but is the same as the shape of the dominant Japanese  cultivars.  However,  the appearance of ‘Amichanmai’ grains is considered inferior to that of ‘Akitakomachi’ grains. Furthermore, the amylose content of ‘Amichanmai’ rice is almost 30%, which is 14% higher than that of ‘Akitakomachi’ rice. Therefore, ‘Amichanmai’ rice may be suitable for producing rice noodles.},
