The hard wheat cultivar Yumeakari is used in bread and Chinese noodles. This cultivar was developed at the Aichi Agricultural Research Center and was registered by the seed and seedling section of MAFF in May 2014. To extend the planted area of Yumeakari in Aichi, a stable cultivation method based on yield and grain quality must be established. In the present study, we investigated the effects of sowing time on the expression of varietal characteristics in Yumeakari. We conducted our experiments at the Aichi Agricultural Research Center during 2010-2012. We examined the effects of six different sowing times (early, somewhat early, optimal, somewhat late, late, and extremely late) on the growth, yield, and grain quality. We showed that seeds sown at the optimal sowing time, i.e., mid-November, showed the highest varietal characteristics. In addition, we determined that the seeds of Yumeakari could successfully be sown throughout the month of November; this range of acceptable sowing period occurred approximately 10 days earlier than that of Nourin 61. We propose that for early sowing, increased application of manure during the formative period of young ears and at the time of full heading may be effective. On the other hand, for late sowing, an increased seed quantity may be effective.
