为探索适于杂交水稻育种者应用的鉴定试验方法，提高选种的准确性和效率，我们在多年交叉杂交配组的基础上，按照不完全双列交配方式，将所选育的７个高代恢复材料与１０个引进的不育系配组７０对组合，进行田间试验方法研究。研究结果表明：不完全双列遗传交配方式，应用于杂交水稻育种中，宜采用裂区设计，以相同恢复系（或不育系）所配组合组成主区，相应地以不育系（或恢复系）所配组合为副区，主区随机排列，副区随机或顺序排列。主区中应设置不同熟性的对照种。
In order to explore the identification test method suitable for the hybrid rice breeder application and improve the accuracy and efficiency of the selection, based on the multi-year cross hybridization group, according to the incomplete double-row mating method, the selected seven high A total of 70 combinations of restorer material and 10 introduced CMS lines were used for field experiment. The results showed that the incomplete double-row genetic mating mode was applied in hybrid rice breeding. The split-plot design should be adopted and the main restorer (or sterile line) Recovery Department) with a combination of deputy district, the main area of random arrangement, deputy district randomly or in sequence. The main area should be set to different maturity of the control species.
