摘　　要：松粳212是黑龙江省农业科学院生物技术研究所以五优稻4号为母本、松粳12为父本进行人工杂交,利用“2+1+1”水稻后代材料鉴定模式选育出的抗倒伏、高食味粳稻新品种。该品种于2023年通过黑龙江省农作物品种审定委员会审定,适宜在黑龙江省第一积温带上限区域种植。倒伏会给水稻造成不同程度的减产及品质下降,水稻品种自身的抗倒伏能力是其维持正常生长和产量的关键。利用“2+1+1”水稻后代材料鉴定模式,可在高肥力压力下有效筛选出抗倒伏能力强的水稻品种。Songgeng-212 is a new japonica rice variety with lodging resistance and high taste,which was artificially hybridized with Wuyoudao-4 as female parent and Songgeng-12 as male parent by using the "2+1+1" progeny material identification model of Heilongjiang Academy of Agricultural Sciences.The variety was approved by the Heilongjiang Provincial Crop Variety Certification Committee in 2023 and is suitable for planting in the upper limit area of the first accumulative temperate zone in Heilongjiang Province.Lodging will lead to different degrees of yield reduction and quality decline of rice.The lodging resistance of rice varieties is the key to maintain normal growth and yield.Using the "2+1+1" progeny material identification model,rice varieties with strong lodging resistance can be effectively screened under high fertility pressure.
