中文摘要：

萝卜(Raphanus sativus L.) 是世界范围的一条重要蔬菜罪。高营养的质量在它的基因改进和生产是批评的。42 中国萝卜栽培变种的营养的质量在这研究被分析。六个营养的事实，干物质( DM )，粗纤维( CF )，全部的可溶的糖( TSS )，维生素 C ( VC )，蛋白质，和硝酸盐的内容，从 29.7～88.2 ， 4.507～18.546 ， 2.233～15.457 ， 0.1416～0.3341 ， 0.34～1.15 ，和 1.81～5.89 g kg ? 1 新鲜重量( FW )分别地。在 42 萝卜栽培变种之中的重要差别在营养的事实的内容被检测。数据受到跨关联的分析和种量分析(PCA ) 。DM 内容断然与 TSS 的内容被相关，这被发现(r = 0.7104 ) ， VC (r =0.4011 ) 和蛋白质(r = 0.4120 ) 。萝卜的维生素 C (VC ) 内容显示出一道正相关(r = 0.3300 ) 与蛋白质内容。根据种量分析，从 42 萝卜栽培变种， Nau-17， Nau-28， Nau-6， Nau-11， Nau-10， Nau-27，和 Nau-31 在全面评估与很高的分数被检测。营养的事实内容的丰富的差异发生在不同萝卜遗传型，这能被结束，并且 PCA 分析为与高质量选择萝卜细菌原生质是有效的。结果能贡献营养的质量的有用知识，并且在萝卜为精英栽培变种发展和营养的事实的继承学习提供重要细菌原生质。

英文摘要：

Radish （Raphanus sativus L.） is an important vegetable crop worldwide. High nutritional quality was critical in its genetic improvement and production. The nutritional quality of 42 Chinese radish cultivars was analyzed in this study. The contents of six nutritional facts, dry matter （DM）, crude fiber （CF）, total soluble sugar （TSS）, vitamin C （Vc）, protein, and nitrate, ranged from 29.7 to 88.2, 4.507 to 18.546, 2.233 to 15.457, 0.1416 to 0.3341, 0.34 to 1.15, and 1.81 to 5.89 g·kg^-1 fresh weight （FW）, respectively. Significant differences among the 42 radish cultivars were detected in the contents of nutritional facts. The data were subjected to cross-correlation analysis and principal component analysis （PCA）. It was found that DM content was positively correlated with the content of TSS （r=0.7104）, Vc （r=0.4011） and protein （r=0.4120）. Vitamin C （Vc） content of radish showed a positive correlation （r = 0.3300） with the protein content. According to the principal component analysis, out of the 42 radish cultivars, Nau-17, Nau-28, Nau-6, Nau-11, Nau-10, Nau-27, and Nau-31 were detected with very high scores in comprehensive evaluation. It could be concluded that abundant diversity of nutritional fact content occurred in different radish genotypes, and PCA analysis was effective for selecting radish germplasm with high quality. The results could contribute useful knowledge of nutritional quality, and provide important germplasms for the elite cultivar development and the inheritance study of nutritional facts in radish.
