摘要 C两优266是湖南省核农学与航天育种研究所选育的R07266恢复系与湖南农业大学选育的C815S不育系配组育成的两系杂交晚稻新组合。该组合具有如下特点:高产(比高产型对照天优华占产量高)、多抗(抗倒、抗病)、耐低温、米质优(3项指标达国标1级,3项指标达国标2级);株型集散适中形态好,茎秆粗硬,后期落色青秀,中穗型且穗粒结构合理;生育期适中,适应性广等特点。2013年5月通过湖南省农作物品种审定。 C-liangyou266 is a new two-line late hybrid rice combination, its restorer line R07266 was bred by Hunan Institute of Nuclear Agronomy and Space Breeding and its sterile line C815S was bred by Hunan Agricultural University. The combination has a lot of good characteristics, such as high-yielding(its yield was higher than control Tianyouhua, a high-yielding rice variety), lodging-resistant, diseaseresistant and low-temperature tolerant, high quality(three indexes reached the first level of national standards, and another three indexes reached the second level of national standards); the plant type presented a not compact and not loose shape, the stem was thick and hard, the plant color in mature period was green and clear, and it presented a middle panicle type with a reasonable structure; its growth period was moderate, and it adapted to a wide range environment.
