Walnut(Juglans regia) is an important economic tree.The fruit and growth traits are typically controlled by multiple quantitative genes,which are susceptible to the influence of environment.Constructing linkage map of J.regia by DNA markers and locating the QTL of mainly economic traits are the basic link of developing molecular-design-breeding for J.regia. In this research,a genetic linkage map of Juglans regia was constructed with SRAP markers in 110 F1 progeny derived from the cross of‘Yuanlin’an...
