[目的]对辽南地区选育和引进的17个糯玉米自交系农艺性状的遗传多样性及其杂种优势类群进行分析。[方法]采用NCⅡ试验设计，选用不同杂种优势类群且国内常用的4个糯玉米自交系为测验种，对辽南地区17个外引和自选糯玉米自交系进行研究。[结果]17份糯玉米自交系的主要农艺性状间存在显著遗传差异，通过聚类分析划分为4个杂优类群。[结论]17份糯玉米自交系农艺性状好，优良性状遗传力高、一般配合力好，各个类群间存在杂种优势，但遗传基础不宽。
[目的]對遼南地區選育和引進的17箇糯玉米自交繫農藝性狀的遺傳多樣性及其雜種優勢類群進行分析。[方法]採用NCⅡ試驗設計，選用不同雜種優勢類群且國內常用的4箇糯玉米自交繫為測驗種，對遼南地區17箇外引和自選糯玉米自交繫進行研究。[結果]17份糯玉米自交繫的主要農藝性狀間存在顯著遺傳差異，通過聚類分析劃分為4箇雜優類群。[結論]17份糯玉米自交繫農藝性狀好，優良性狀遺傳力高、一般配閤力好，各箇類群間存在雜種優勢，但遺傳基礎不寬。

Objective] Genetic diversity and heterosis groups of 17 Waxy maize inbreed lines introduced in Liaonan area were analyzed. [Method] By NC II experiment design, the 4 inbred lines belonged to different heterosis groups were selected as the testing varieties, and the agronomic traits and heterosis groups of 17 Waxy maize inbreed lines were also studied in Liaonan. [Result] There were significant genetic diversity in the main agronomic traits and 17 inbreed lines were divided into 4 heterosis groups through the cluster analysis. [Conclusion] 17 waxy maize inbred lines had good agronomic traits, high good trait heritability, GCA of good features, problems heterosis among the various groups, but the genetic basis between them was not wide.
