    Implementation of different relationship estimate methodologies in breeding value prediction in kiwiberry (Actinidia arguta)

    In dioecious crops such as Actinidia arguta (kiwiberries), some of the main challenges when breeding for fruit characteristics are the selection of potential male parents and the long juvenile period. Currently, ...
