【Objective】To investigate the characteristics of turnip germplasm resources in Xinjiang and to provide a scientific basis for the breeding of Xinjiang turnip.【Method】The total phenolics,flavonoids,soluble sugar,soluble protein,soluble solid,ascorbic acid,starch and titratable acidity content were determined and compared through the introduction of different sources of turnip,different turnip cultivars as experimental materials were studied in Keping and Shule County in southern Xinjiang.【Result】The results showed that the same turnip cultivars in different locations showed different nutritional quality,the nutritional quality in Keping County is superior to that of Shule County.The total phenolic content,soluble sugar content and soluble solid content showed a significant positive correlation,the flavonoid content and soluble sugar content showed a significant positive correlation,the protein content and ascorbic acid content showed a significant positive correlation,soluble solid content and starch content showed a highly significant positive correlation.【Conclusion】In combination with biological characteristics and nutritional characteristics of fruit,varieties suitable for planting in southern Xinjiang were selected as follows: Xinxing circle turnip,Jinqiu turnip,Keping green cone turnip,Tiandihe turnip,Keping green oblate turnip,Keping purple cone turnip and Japan turnip,which can be demonstrated and popularized in larger area.
