Abstract：To select high-quality non-heading Chinese cabbage varieties suitable for cultivation in different seasons and improve year-round production,50 hybrid combinations were used as experimental materials.A comprehensive evalua-tion of their agronomic traits was conducted using multivariate statistical methods,including principal component analy-sis and the membership function method.The results showed that the genetic variation coefficients of all traits exceeded 10%,with petiole length,plant height,and leaf width exhibiting high improvement potential.Based on market preferenc-es,15 combinations with superior commercial quality were selected.Principal component analysis extracted four key fac-tors with a cumulative contribution rate of 71.43%.Further membership function method identified 14 combinations with comprehensive traits outperforming the control variety Dongzhixian,among which 7 combinations,including Z2,Z23,Z31,Z33,Z36,Z37 and Z46,performed outstandingly in both screening stages.Comparative trials revealed that Z21 and Z23 demonstrated good commercial traits,combining bolting resistance with high yield,making them suitable for early spring and overwintering cultivation.In contrast,combinations such as Z31 and Z33,though high-yielding but lacked bolt-ing-resistant,were recommended for summer or autumn cultivation.
