汕优５５９系江苏沿海地区农科所继特优５５９之后配组育成的又一个集丰、抗、优于一体，综合性状突出的杂交籼稻新组合。在１９９５～１９９７年江苏省区域试验和生产试验中，连续三年夺冠，产量均较对照汕优６３增产７％以上，一般亩产６５０ｋｇ左右，产量潜力８００ｋｇ／亩以上。抗稻瘟病，中抗白叶枯病。米质较优，糙米率、精米率、整精米率、碱消值、直链淀粉含量、蛋白质含量等６项指标达部颁优质米一级标准。高产栽培应在稳定穗数的基础上主攻大穗，提高结实率，充分发挥其大穗增产优势。
Shanyou 559 Department of Agricultural Sciences in Jiangsu Province following the Teyou 559 with a combination of breeding Feng, anti-superior, better than one, the comprehensive trait of hybrid indica hybrid combinations. In 1995 ~ 1997, Jiangsu Province, regional trials and production trials, won three consecutive years, the yield increased by more than 7% compared with the control Shanyou 63, generally about 650kg per mu, the yield potential of 800kg / mu or more. Blast resistance, resistance to bacterial blight. The six indicators of superior rice quality, brown rice rate, milled rice rate, milled rice rate, alkali consumption, amylose content, protein content reached the ministerial level of a rice quality standards. High-yielding cultivation should be based on the number of stable panicle main attack spike, improve seed setting rate, give full play to its large spike yield advantage.
