| 摘 要： | 为了深入了解罗汉果种质遗传改良潜力和探讨性状遗传相关关系，该文采用完全随机区组试验设计，系统调查18个罗汉果无性系种质的26个性状，并进行方差、主成分、相关和通径分析。结果表明:这些种质的26个性状中，有25个性状均存在较大遗传变异，且在长势、生育期、营养品质、产量及甜苷方面变异突出，具有良好的遗传改良潜力； 单果重与果纵径呈极显著正相关；总苷含量与果形呈极显著正相关。故高产品种选育应高度关注果纵径，选择果纵径较长的株系；高总苷含量品种选育应高度关注果形指数，选择果形指数较大的株系。

| Abstract: | To explore potential of genetic improvement and relation of genetic characters in 18 clonal lines of Siraitia grosvenorii germplasms,their 26 characters were investigated by analysis of variance,principal component,correlation and path analyses in a randomized complete block experiment.The results indicate that 25 characters among 26 characters were greatly different from each other in these germplasms.Furthermore,the variations in growth vigour,growth period,nutritional quality,yield and mogroside content ... |
