Strategy to minimize phenotyping in the selection of new table grape varieties

Morphological evaluation of large progenies is a problem in plant breeding programs, because the need for skilled labor capable characterizing various descriptors number individuals ripening simultaneously. In addition, maintenance field involves an unsustainable consumption resources that could be reduced. Marker-assisted selection (MAS) offers possibility accelerating process with consequent saving resources. The aim this work to propose methodology minimizes phenotyping thousands these programs. consists analyzing complete progeny limited markers (27 SSR (Simple Sequence Repeat)) and reduced description morphological characters on so-called training collection individuals) obtained Mstrat software. With strategy, it was possible estimate traits such as berry skin color or seedlessness more than 2000 probability 90%, discard 50% without muscat linked alleles.
