摘　　要：为提高辽宁中部平原稻区在高端稻米市场竞争力和满足市场对优质香稻的日益需求,对13个香型粳稻品种在本地区同一管理模式下的产量、品质及2-乙酰-1-吡咯啉(2AP)含量进行分析,并对各指标进行综合评价。结果表明,辽粳香1号等8个品种产量超过9000 kg/hm^(2),不同品种取得高产的因素有差异;直链淀粉含量、整精米率、垩白度和食味值是限制各品种优质米等级的主要因素;香气主要活性物质2AP在辽粳香1号、盐粳476、盐粳935、盐粳939和华香粳1号中有较高水平,且显著高于其他品种;主成分分析表明,前4个主成分的累计方差贡献率在80%以上,综合排名前5的品种依次为铁粳香1号、隆粳香6号、盐粳476、辽粳香1号和吉源香1号。综合产量、品质及2AP含量,本研究中辽粳香1号可作为辽宁中部平原稻区优质香型粳稻生产供选品种。In order to improve the competitiveness in the high-end rice market and meet the increasing demand for high-quality fragrant rice,the yield,rice quality and 2-acetyl-1-pyrroline(2AP)content of 13 fragrant japonica rice cultivars were studied under the same management mode in plain rice production area in central Liaoning,the indexes were comprehensively evaluated.The results showed that the yields of Liaogengxiang 1 and the other eight cultivars could exceed 9000 kg/ha,and factors for high yields varied with different cultivars;amylose content,head rice rate,chalkiness and taste value were the main factors limiting the grade of high-quality rice;the 2AP content of Liaojingxiang 1,Yanjing 476,Yanjing 935,Yanjing 939 and Huaxiangjing 1 were significantly higher than that of other cultivars.Principal component analysis showed that the cumulative variance contribution rate of the first four principal components were above 80%,and the top five cultivars were Tiejingxiang 1,Longjingxiang 6,Yanjing 476,Liaojingxiang 1 and Jiyuanxiang 1.Considering yield,quality and 2AP content,Liaojingxiang 1 could be selected as a high-quality fragrance japonica rice cultivar in plain rice production region in central Liaoning.
