为了解12年来广西糯玉米品种种质来源、构成，探析品种选育路径，对2011年至2022年广西审定的173个糯玉米品种进行分析。结果表明：广西糯玉米主要种质由A（宜山糯）类、B（京科糯2000）类、C（万糯2000）类、D（燕禾金2000）类、E（中糯1号）类、F（中糯2号）类、G（衡白522）类、H（华珍）类、I（花甜糯179）类、J（NA群体）类、K（NB群体）类等11类种质构成，A、B类种质是广西糯玉米品种的基础种质。根据亲本主要种质类型，排除年份间的环境变化因素后，可将93个品种归入AB等15个群组。各群组穗部性状相关分析表明，整体上看，穗行数、穗粗同产量及其它穗部性状分别呈显著负效应及无显著效应，同时，群组相关性受到种质组合及组配模式共同影响，通常情况下种质组合的影响力更强，但涉及F类种质的群组相反。因此，穗部性状选育重点要根据亲本主要种质类型确定。

Abstract:In order to understand the germplasm source and composition of waxy maize varieties in Guangxi in 12 years,Proven variety breeding path,Analysis of 173 Waxy Maize Varieties Approved in Guangxi from 2011 to 2022. The results showed that the main germplasm of waxy maize in Guangxi was composed of 11 categorys of germplasm, including A ( Yishannuo), B ( Jingkenuo 2000), C ( Wannuo 2000), D ( Yanhejin 2000), E ( Zhongnuo 1), F ( Zhongnuo 2), G ( Hengbai 522), H ( Huazhen), I ( Huatiannuo 179), J ( NA population) and K ( NB population)，A and B germplasms are basic germplasms of waxy maize varieties in Guangxi.According to the main germplasm types of parents, 93 varieties could be classified into 15 groups such as AB and so on after excluding the environmental factors between years.The correlation analysis of yield and ear traits showed that, on the whole, the row number per ear, ear diameter and yield and other ear traits showed significant negative effects and no obvious effect respectively, at the same time, the expression of significantly related trait combinations in groups is affected by the germplasm combination and the matching pattern.Generally, the influence of germplasm combinations is stronger, but the group involving F germplasm is the opposite.Therefore, the breeding focus of ear traits should be determined according to the main germplasm types of parents.
