Sharka (Plum Pox Virus) Disease: Genetics of resistance to the disease in apricot and molecular studies

28183

Sharka disease is caused by Plum Pox Virus (PPV) which belongs to Potyviridae family. It is accepted as one of the most harmful diseases of stone fruits considering economic and social impacts [1]. The cost caused by the disease for the last 30 years was estimated to be 10 milyar euros [2]. The protection methods have not been affective to halt the spread of the disease in Europa. Understanding molecular mechanism of the disease resistance and breeding resistant varieties have become promising objective in apricot breeding programs. European apricot breeding programs initiated breeding programs crossing the resistant North American cultivars with the susceptible European cultivars. Stark Early Orange, Goldrich, Harcot, Harleyn, and Stella are the main cultivars used as resistance donor in the breeding programs. Having considered phenotypic anaylsis of segregation population some researchers proposed single gene for the resistance while many researches reported multiple locus for the resistance. Most of the apricot molecular maps constructed with phenotypic data revealed a major QTL on linkage group 1 and two small loci on LG3 and LG5, respectively.
