Comparison of French and Oriental rootstocks for the Packham's Triumph pear at Bathurst, New South Wales

Abstract

Of eleven rootstocks tested with Packham's Triumph pear over twenty two years in an orchard trial at Bathurst, New South Wales, P. calleryana stocks were superior to those of P. pashia and P. communis. All five strains of P. caueryana produced more vigorous and better cropping frees than P. pashia which performed better than P. communis seedlings (from varieties Winter Bartlett, Beurre Bosc, Winter Cole), and the East Mulling selection B1. These latter stock were unsatisfactory. Of the five clonal strains of P. calleryana the D6 and PC4 strains produced the most vigorous and highest yielding trees. D6 performed equally well whether as clonal stock or as seedlings.
