A genetic linkage map was constructed from a F1 population comprising 94 seedlings derived from a cross between 'Chonghuadali'×'Shinseiki' using mapmaker/exp 3.0.The map consisted of 19 SSR markers and 315 SRAP markers which belong to 18 linkage groups and spans 1 300 cM with an average genetic distance of 3.9 cM.The interval mapping was used to identify quantitative trait loci(QTL) associated with fruit developing period and fruit shape index in the F1 population.The results indicated 7 QTLs were linked to...
