Head cracking is the most serious physiological disease in the production of cabbage. The splitting resistance of 7 spring and 8 autumn cultivars were evaluated under natural conditions by comparison of cracking type, cracking rate and degree of cracking extent, and the grading system of cabbage head splitting was established according to the number of split leaf layers and area of the maximum head cracking. The head splitting index of post harvesting-5 days for spring cabbage and 15 days for autumn cabbage can be used to accurately identify head splitting resistance of cabbage. The varieties can be divided into 5 levels: High Resistance, Resistance, Moderate Resistance, Susceptibility and High Susceptibility. Further it was used for screening high resistance to head-splitting of 59 germplasm resources, and some high resistant cultivars were screened out. Also the indoor head soak method was evaluated at the same time. Through head splitting of 15 cultivars survey and analysis by indoor soak method, we can achieved that the method can also identify resistance to splitting-head of cabbage accurately. The research developed a set of identification method and standard for screening splitting resistance germplasm. These resistance germplasm would provide materials for theory and breeding of cabbage.
