对02428、cpslo17、培矮64在三系杂交稻中的利用进行分析,结果表明,亲和力高低依次为cpslo17、培矮64、02428。cpslo17、培矮64含有对籼粳不育系的恢复基因,02428含有对粳稻不育系的恢复基因。三者与BT型不育系的产量配合力都较好,杂种有明显的优势。单株产量主要受单株有效穗数和每穗粒数的影响。 The analysis of utilization of 02428, cpslo17 and Pei’ai 64 in three - line hybrid rice showed that the order of affinities was cpslo17 and Pei’ai 64,02428. cpslo17, Pei’ai 64 contain the restorer gene of indica and japonica CMS lines, and 02428 contains the restorer gene of japonica CMS line. The three strains and BT type CMS with better yield cohesion, hybrids have obvious advantages. The yield per plant was mainly affected by the effective panicle per plant and the grains per panicle.
