摘要
Y两优5866是福州市亚丰水稻育种研究中心利用引自湖南杂交水稻研究中心育成的光温敏核不育系Y58S与自育籼型恢复系亚恢66配组而成的两系杂交中籼新组合。该组合参加福建省中稻组区域试验,米质达部颁三等优质食用稻品种标准,表现出熟期适宜、穗大粒多、结实率高、丰产性和稳产性好、米质优、适应性广、熟期转色好等特点,2015年通过福建省品种审定委员会审定(闽审稻2015001)。介绍了Y两优5866的选育过程、区试产量表现、特征特性,高产栽培、制种技术,为品种的推广应用提供参考。
Y Liangyou 5866 was a new two-line hybrid medium indica combination developed by Yafeng Rice Breeding Research Center in Fuzhou City by crossing between the Photo-thermo-sensitive genic male sterile line Y58S introduced from Hunan Hybrid Rice Research Center and the self-bred indica restorer line Yahui66.This combination has taken part in the regional trial of semilate rice in Fujian Province,and the rice quality reached the standard of three-grade high quality rice variety issued by the ministry of rice quality,showing the characteristics such as suitable ripening stage,large panicle and grains,high ripening rate,good yielding ability and stability,excellent rice quality,wide adaptability,and good colouring at ripening stage,which was approved by Fujian Variety Examination Committee in 2015(2015001).The breeding process,yield of regional trial,characteristics and high-yield cultivation and seed production technology of Y Liangyou 5866 were introduced in this paper.
