摘要： 以黑龙江省第二积温带2014年审定的10个水稻新品种为材料，采用随机区组设计，分析了黑龙江省第二积温带水稻新品种食味品质性状的稳定性。结果表明，供试的10个品种中，金禾2号的食味品质性状比较稳定，受环境的影响较小；绥稻3号的食味品质性状不稳定，受环境影响较大，但在适宜的环境条件下能获得较好的品质。供试10个品种中有7个品种其亲本来自2个骨干亲本，形成2条主干系，分别是绥粳3号和绥粳4号干系。参试品种中由绥粳4号作为亲本育成或者衍生出的绥粳系品种比较多，主要都是香粳类型的品种。由绥粳3号干系和绥粳4号干系育成和衍生的水稻品种食味品质性状稳定性较差。

Abstract: In order to analysis the stability of eating quality traits of rice in the second accumulated temperature zone in Heilongjiang Province, a experiment was carried out using randomized block design in 2014, using 10 rice varieties as materials. The results showed that the eating quality traits of Jinhe 2 was less influenced by the environment; the eating quality traits of Suidao 3 was greatly influenced by the environment, but it can get fine eating quality in the appropriate conditions.
