Abstract：In order to identify the characteristics of superior-yield and high-quality carrot varieties，
this paper took the main cultivar ‘Mendel No.3’（MDE）and main promotion variety ‘Tongdelizhenjiuhong’（TDL），‘Shengyahong’（SYH），‘Hongmengluo’（HML），‘Nielsen No.2’（NES2），and ‘Nielsen
No.7’（NES7）were used as materials for field experiments，carried out analysis on the yield and quality of different carrot varieties in Laixi Regio，and studied the differences in yield，exterior quality，and nutritional quality of different carrot varieties．The results showed that compared with the main cultivar MDE，the yields of TDL cultivated in autumn and NES2 cultivated in spring had increased by 24.20% and 10.20%，respectively．There were no significant differences in the symmetry ratio，spinal cord rate of leaf area and flesh root．The nutritional quality of carotene and VC was similar to that of the major sowing varieties. TDL and NES2 had better promotion potential．
