株两优 0 2是用广亲和低温敏两用核不育系株 1S与抗稻瘟病优质父本ZR0 2选配而成的两系杂交早稻新组合 ,表现高产稳产 ,抗多种病虫害 ,生育期适宜 ,食味品质好 ,在长江流域具有广泛的适应性。 2 0 0 4年 1 0月通过国家农作物品种审定委员会审定。认为多抗源聚合杂交是选育对稻瘟病具广谱抗性品种的有效途径 ,而选育偏籼型广亲和低温敏核不育系是选育亚种间杂交早稻的有效途径 Zhu Liang 2 0 is a new combination of two-line early-maturing hybrid rice made up of broad-compatible low-temperature-sensitive genic male sterile line 1S and high-quality male parent ZR0 2 of blast resistance, showing high and stable yield, resistance to various pests and diseases, Suitable growth period, good eating quality, in the Yangtze River basin has a wide range of adaptability. In January 2004, it was approved by the National Crop Variety Approval Committee. It is considered that multi-resistant hybridization is an effective way to breed broad-spectrum resistant varieties to rice blast disease, and breeding of Indica-compatible broad-compatible and low-temperature sensitive genic male sterile lines is an effective way to breed intersubspecific hybrid early rice
