摘　　要： [目的]选育粳型亲籼系。[方法]选用6个籼稻、6个粳稻和6个广亲和测验种,以F1代花粉育性和小穗育性为指标,测定了5个待测粳型亲籼系的亲籼性。[结果]待测粳型亲籼系G2123、G2417、G2410和G3005亲籼、不亲粳,为特异亲籼系;G2615不亲籼,也不亲粳,为不亲和系。同时探讨了粳型亲籼系亲籼性测定时的测验种、育性指标、花粉育性和小穗育性的测定方法,分析了G2417高亲籼性的原因。[结论]G2417自交结实率(小穗育性)95.1%,与6个籼稻测验种杂交的F1代平均结实率(小穗育性)94.9%,是个亲籼性极好、综合性状优良的亲籼系。 [Objective ] The aim was to breed the indica-compatible japonica lines （ICJL）. [ Method ] The indica-compatibility of 5 candidate ICJLs were tested based on the pollen fertility and spikelet fertility of F： hybrids with 6 indica testers ,6 japonica testers and 6 and middle test- ers. [ Result] Candidate ICJL G2123, G2g17, G2410 and G3005 were grouped into the exceptionally indica-compafible lines based on their high indiea-compatibility and low japonica-compatibility. Candidate ICJL G2615 was grouped into the non-compatible lines on their low indica- compatibility and low japonica-compatibility. The testers, fertility identification standards, test methods of pollen fertility and spikelet fertility were discussed when the compatibility of CICJL was tested. The reason of the indica-compatibility in G2417 was analyzed. [ Conclusion] The selfing seed setting rate （ spikelet fertility） of G2417 was 95.1% and the crossing seed setting rate （ spikelet fertility） of F~ hybrid between G2417 and indica testers was 94.9%. G2417 had high indica-compatibility and good synthesis-character.
