Commercial production of apricot is severely affected by sensitivity to climatic conditions, an adaptive feature essential for cycling between vegetative or floral growth and dormancy. Yield losses are due to either late winter or early spring frosts or inhibited vegetative or floral growth caused by unfulfilled chilling requirement (CR). Studies in this dissertation developed the first high-density apricot linkage map; followed by a comparative mapping strategy to validate conservation of synteny, genome collinearity and stable quantitative trait loci (QTLs) controlling CR and bud break between apricot and peach; and ultimately attempt to identify key candidate genes following a linkage disequilibrium-based …
