【Abstract】 The character of late sowing wheat in Huanghuai regions was short growth period, not enough growth time before winter and fast growth in next spring, late and short-time differentiation of immature ear, then the differentiation of immature ear speeded up in the middle to late stage, fast filling at the beginning, more accumulation of dry material but short time filling stage and big variation of 1000-seed weight.
