The kiwifruit is one of the most recently domesticated fruit crops. Starting from the native China, kiwifruit was introduced in New Zealand where it was commercially cultivated widely since the mid-20th century. Today, China, New Zealand, Italy, Chile, and Greece produce not less than 75%-80% of world commercial kiwifruit annual yield. Although Actinidia is a challenging genus - dioecious, polyploid, taxonomically difficult because of reticulate evolution - accessing of molecular genetics and genomics to predict outputs from crosses turned out to be a great tool. Molecular markers became over the years popular among breeders and they have been used to map single traits and to carry out marker-assisted selection (MAS). This chapter provides a detailed overview of available information on markers and alleles for different genes/QTLs that have been identified for gender discrimination, identification of desirable characters associated with fruit quality, diseases resistance selection, phylogenetic, and varietal identification in kiwifruit. Overall, this chapter represents a useful resource for all concerned with kiwifruit molecular breeding.

Abstract
The kiwifruit is one of the most recently domesticated fruit crops. Starting from the native China, kiwifruit was introduced in New Zealand where it was commercially cultivated widely since the mid-20th century. Today, China, New Zealand, Italy, Chile, and Greece produce not less than 75%-80% of world commercial kiwifruit annual yield. Although Actinidia is a challenging genus - dioecious, polyploid, taxonomically difficult because of reticulate evolution - accessing of molecular genetics and genomics to predict outputs from crosses turned out to be a great tool. Molecular markers became over the years popular among breeders and they have been used to map single traits and to carry out marker-assisted selection (MAS). This chapter provides a detailed overview of available information on markers and alleles for different genes/QTLs that have been identified for gender discrimination, identification of desirable characters associated with fruit quality, diseases resistance selection, phylogenetic, and varietal identification in kiwifruit. Overall, this chapter represents a useful resource for all concerned with kiwifruit molecular breeding.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
