摘　　要：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 。Zhuliangyou 02 is a new early season indica hybrid rice combination developed by Academy of Seed Science of Hunan Yahua and Zhuzhou Agricultural Science Research Institute of Hunan. It shows high and stable yield, wide adaptability and good eating quality. It is resistant to blast, moderately resistant to bacterial leaf blight (BLB) and brown planthopper (BPH). Its female parent Zhu 1S is an early season indica TGMS line with its critical temperature lower than 23℃. Its male parent ZR02 is a two-line early season rice restorer line with blast resistance and good grain quality. It was registered and released to commercial production in China in October, 2004. Its breeding procedure, characteristics, major cultural practices and hybrid seed production techniques were introduced.
