Abstract
An initial genetic linkage map for blueberry has been constructed from over 70 random amplified polymorphic DNA (RAPD) markers that segregated 1∶1 in a testcross population of 38 plants. The mapping population was derived from a cross between two diploid blueberry plants: the F1 interspecific hybrid (Vaccinium darrowi Camp x V. elliottii Chapm.) and another V. darrowi plant. The map currently comprises 12 linkage groups (in agreement with the basic blueberry chromosome number) and covers a total genetic distance of over 950cM, with a range of 3–30cM between adjacent markers. The use of such a map for identifying molecular markers linked to genes controlling chilling requirement and cold hardiness is discussed.Keywords
