Abstract: [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.

摘要： [目的]研究新疆芜菁的种质资源特性,为芜菁育种提供科学的理论依据.[方法]引进不同来源芜菁,以不同品种芜菁作为试验材料,对总酚、黄酮、可溶性糖、蛋白质、可溶性固形物、抗坏血酸、淀粉、可滴定酸含量进行测定与比较.[结果]相同芜菁品种在不同地点表现出营养品质不同,柯坪县的芜菁品质要优于疏勒县的芜菁品质.总酚含量与可溶性糖含量、可溶性固形物含量均呈显著正相关,黄酮含量与可溶性糖含量呈显著正相关,蛋白质含量与抗坏血酸含量呈显著正相关,可溶性固形物含量与淀粉含量呈极显著正相关.[结论]结合生物学性状与果实营养品质特性,筛选出符合新疆南疆种植的品种为,新星圆蔓菁,金秋芜菁,柯坪-绿-圆锥,天地禾芜菁,柯坪-绿-扁圆,柯坪-紫-圆锥,日本小芜菁,可以进行示范并大面积推广.
