Both selection of parents before cross-fertilization to make great genetic differences and selection in progenies under guide of effective techniques are the two nuts during new tea variety breeding. They are the main purposes of conducting genetic diversity and constructing linkage map for tea (Camellia sinensis (L.) O. Kuntze). Research on genetic diversity and linkage map construction are great useful in enhancing breeding efficiency. There are several reports on genetic diversity and linkage map constru...
