Abstract
Using F2 population derived from the hybrid of Lycopersicon esculentum Mill. ‘XF 98-7’ × Lycopersicon pim pinellifolium LA2184, a SSR genetic linkage map of tomato is constructed. The map contains 112 markers and spans 808. 4 cM with an average distance of 7.22 cM between loci. Two quantitative trait loci (QTLs) for first flower node on chromosomes 5 and 11, two QTLs for number of flowers per truss on chromosomes 2 and 5, and five QTLs for fruit weight on chromosomes 1, 2, 3, 9 and 12 are identified.
