Early maturity is the most important trait for wheat cultivation in southwestern Japan since rainfall during the late ripening stage can often cause inferior grain quality. Early sowing facilitates an early maturity. However, early sowing of conventional spring wheat causes the stem to elongate rapidly during winter, resulting in frost injury. A new winter wheat Iwainodaichi, recently bred in Kyushu Okinawa Agricultural Research Center, is a prospect for early sowing since stem elongation of winter wheat is not accelerated even if it is seeded early. The growth and development of winter wheat when seeded early is expected to differ from that of spring wheat when seeded on the standard date. The aim of this study is to determine eco-morphological traits and to develop new cultivation techniques for Iwainodaichi when seeded early.
