- 为推广综合性状优良的耐盐碱水稻新品种齐粳8号，系统介绍了齐粳8号耐盐碱水稻的亲本来源及选育过程、特征特性及栽培技术要点和耐盐碱情况。齐粳8号是黑龙江省农业科学院齐齐哈尔分院以优质高产品种垦稻10号为母本，以耐盐碱抗倒伏香型品种绥粳18为父本，进行有性杂交，通过系谱法与集团相结合的方法选育而成。2021－2022年参加黑龙江省联合体第二积温带早熟期组区域试验平均产量8 668.7 kg·hm-2，2023年生产试验平均产量8 941.0 kg·hm-2，分别较对照品种龙粳21增产8.3%和 6.6%。2024年通过黑龙江省农作物品种审定委员会审定，审定编号为黑审稻2024L0039。齐粳8号在盐碱胁迫下，分蘖数、干物质质量、实测产量均显著高于对照品种齐粳10号，表现出较强的耐盐碱能力。齐粳8号是集耐盐碱、高产、优质、抗逆于一身的优良香型水稻新品种，需≥10 ℃活动积温2 500 ℃左右，适宜在黑龙江省第二积温区域推广种植。
