从改善植株光能高效利用的株叶形态入手,通过杂交和基因重组,聚合优良性状,创造性地定向培育出晚粳稻新种质“测21”。该种质遗传基础丰富、抗性强、适应性广、配合力好,成为我国常规粳稻育种和杂交粳稻育种的优良核心亲本。项目组共审定秀水04、浙粳22等新品种54个,形成了粳、糯配套,早、中、晚搭配,丰、抗、优兼顾的系列品种优势,其中祥湖84、秀水11和秀水63连续成为我国南方粳稻
Beginning with the improvement of plant leaf morphological characteristics of plant utilizing light and energy efficiently, a new germplasm “Latex 21” was latently cultivated by hybridization, gene recombination and excellent polymerization. The germplasm has rich genetic basis, strong resistance, wide adaptability and good combining ability, and has become an excellent core parent of Chinese conventional japonica rice breeding and japonica hybrid rice breeding. The project team approved a total of 54 new varieties such as Xiushui 04 and Zhejing 22, forming a series of varieties with the matching of japonica and glutinous rice, with early, middle and late nights, with abundance, resistance and superiority. Among them, Xianghu 84, Xiushui 11 and Xiushui 63 consecutive to become China’s southern rice
