Abstract
A HIGH degree of ‘field’ resistance to infection by leaf rust (Puccinia coronata var. lolii) has been developed in perennial ryegrass (Lolium perenne), an open pollinated plant, by selecting individual plants for resistance (as one of several agronomic characters) from the progenies of open pollinated strains. The strains, selected by Corkill et al., were tested for combining ability and other agronomic characters. Several were allowed to interpollinate to form the synthetic variety released as New Zealand perennial ryegrass1.
