粳稻食味相关品质性状的变异与相关性研究刘研李鑫赵一洲毛艇钟顺成王诗宇张战倪善君（辽宁省盐碱地利用研究所，辽宁盘锦124010）摘要为研究粳稻品种食味及相关品质性状的变异特点及相关性，对62份粳稻品种食味值、部分理化品质性状、淀粉的黏滞度进行分析。结果表明，62份粳稻品种测试性状变异系数在3.96%~90.00%，Shannon-Wiener多样性指数在1.279~2.038，62份粳稻品种在品质性状上可划分到4个类群。品种食味值、部分理化性状、RVA谱特征值之间存在显著或极显著的相关性，同时构建了3个回归方程。本研究结果为粳稻优质食味品种选育与性状选择提供了依据。关键词粳稻；食味值；品质性状；RVA谱特征值；变异；相关性中图分类号TS210.1；S511.22文献标识码A文章编号1007-5739（2023）07-0185-04DOI：10.3969/j.issn.1007-5739.2023.07.051开放科学（资源服务）标识码（OSID）：StudyonVariationandCorrelationofTasteandRelatedQualityTraitsinJaponicaRiceLIUYanLIXinZHAOYizhouMAOTingZHONGShunchengWANGShiyuZHANGZhanNIShanjun(LiaoningInstituteofSaline-alkaliLandUtilization,PanjinLiaoning124010)AbstractInordertostudythevariationandcorrelationoftasteandrelatedqualitytraitsofjaponicaricevarieties,thetastevalue,somephysicalandchemicalqualitytraitsandstarchviscosityof62japonicaricevarietieswereanalyzed.Theresultsshowedthatthevariablecoefficientoftesttraitsof62japonicaricevarietiesrangedfrom3.96%to90.00%,andtheShannon-Wienerdiversityindexrangedfrom1.279to2.038.The62japonicaricevarietiescouldbedividedintofourgroupsintermsofqualitytraits.Thereweresignificantorextremelysignificantcorrelationsamongthetastevalue,somephysicalandchemicalpropertiesandRVAspectrumeigenvaluesofthevarieties,andthreeregressionequationswereconstructed.Theresultsofthisstudyprovideabasisforthebreedingandtraitsselectionofjaponicaricewithgoodqualityandtaste.Keywordsjaponicarice;tastevalue;qualitytrait;RVAspectrumeigenvalue;variation;correlation水稻是世界上第二大粮食作物，也是我国重要的粮食作物之一，在我国粮食生产和消费中处于主导地位，是我国65%以上人口的主食[1]。近些年，随着人们生活水平不断提高，稻米品质特别是蒸煮与食味品质的改良越来越受到重视，食味品质已成为今后水稻研究的重要内...
