摘　　要：为天津市适宜种植水稻新品种的选择提供参考,以引进的17个粳稻杂交新组合为材料,采用田间大区试验研究其在天津市稻区作为春播稻和麦茬稻种植的生育期、产量及农艺性状等综合表现。结果表明:粳优1317作为春播稻种植的生育期适宜、结实率较高、产量优势明显,建议在该稻区作为春稻进一步进行示范种植观察其稳产性和抗逆性;粳优619和粳稻59作为麦茬稻种植的生育期适宜,并具有一定产量优势、结实率较高,建议在该稻区将这2个杂交新组合作为麦茬稻进一步进行示范种植,以观察其抗逆性。In order to provide references for breeding new rice cultivars suitable for planting in Tianjin City, a field experiment was conducted on 17 newly introduced japonica rice combinations to explore their general performances of growth period, yield and agronomic traits of spring rice and stubble rice.Results： Spring rice cultivar Jingyou 1317 is of suitable growth period, higher fruit setting rate and obvious yield dominance, which is suggested to be demonstrated in the rice region, so as to observe the yield stability and stress resistance in further;Stubble rice cultivars Jingyou 619 and Jingdao 59 are of appropriate growth period, certain yield dominance and higher fruit setting rate, which were suggested to be demonstrated in further, so as to observe their stress resistance.
