Abstract
With 2 figures AbstractA genetic linkage map for pak‐choi, a very important economical and nutritional vegetable crop in Asia, has been constructed using amplified fragment length polymorphism (AFLP) and simple sequence repeat (SSR) markers based on 180 F2 individuals. It includes 133 AFLP and 74 SSR markers from 57 AFLP and 65 SSR primer combinations, respectively. Fifty SSR markers were previously used to construct a framework map and all AFLP markers and another 24 SSR markers were inserted. The linkage map consists of 10 linkage groups with a total distance of 1123 cM and an average interval of 5.43 cM. Turnip mosaic virus (TuMV) is one of the most important pathogens of pak‐choi. TuRBCH01, a TuMV‐C5 resistance gene, was successfully mapped into R6 linkage group in the present genetic linkage map and was positioned between AFLP markers E36M62‐3 and E44M48‐1.
