汕优559系江苏省沿海地区农科所育成。1998年3月通过江苏省农作物品种审定委员会审定。1998年大面积高产示范田平均单产9.35t/hm~2。表现高产、稳产、抗倒、抗病、品质中上等优点。该组合将成为苏北杂交稻主体品种。 1 安排好播差期,确保花期相遇父母本花期能否在抽穗扬花期良好相遇,这是高产制种的关键。据观察,母本播种至始穗天数62天左右。父本播种至始穗天数110天左右,总叶片数平均
Shanyou 559 Department of Jiangsu Province coastal bred agricultural. March 1998 passed the Jiangsu Province Crop Variety Approval Committee. In 1998 a large area of high yield demonstration plots average yield 9.35t / hm ~ 2. Performance of high yield, stable yield, anti-down, disease resistance, quality superiority. The combination will become the main hybrid rice varieties in northern Jiangsu. 1 arrangements broadcast sowing period, to ensure that the flowering period parents flowering in the flowering period to meet well, which is the key to high-yielding seed. It is observed that the female parent sowing date to the first days of days about 62 days. The male parent sowing to the ear number of days about 110 days, the total number of leaves on average
