Abstract
Winter pea has several advantages on spring pea: higher yield, more rapid spring growth that helps this crop to compete weeds, wider growing area, etc. The aim of this paper was to evaluate the association of some molecular markers with frost tolerance of pea. Forty-one pea recombinant inbred lines (RILs), from F5 generation, obtained by crossing the winter cultivar Checo with the spring line F95-927 were examined during this work both by in vitro (molecular markers analysis) and in field experiments. The results obtained showed a significant correlation betweeen frost tolerance and molecular markers EST1109 and AD59. Also, it has been found that the molecular marker AD159 is associated with earliness character. These associated markers could play an essential role in marker-assisted breeding for winter-hardy pea cultivars.
