Genetically stable population of recombination inbred line (RIL) was derived from a cross between a heat tolerant line 177 and a heat sensitive line 276 of Chinese cabbage (Brassica campestris L. ssp. pekinensls) by single seed descent. The RILs were analyzed using isozyme, RAPD and AFLP techniques in order to find molecular markers that are linked to heat tolerance quantitative trait loci (QTL). The results of variance analysis of single factor indicated that there were 9 molecular markers closely linked with heat toler-
