| Abstract:
Red raspberry (Rubus idaeus) cultivars and selections were screened over two seasons for resistance to postharvest grey mould caused by Botrytis cinerea.. Significant levels (P<0.001) of resistance were found in back-cross generations from R. pileatus Focke and R. occidentalis to R. idaeus. A strong relationship was found between the mean shelf life score and the expected proportion of R. occidentalis and R. pileatus in a clone. Best shelf life (weighted mean of 1.1 fruit out of 10 discarded with rot) was found in material that had both R. pileatus and R. occidentalis in its ancestry. Advanced selections show considerable promise for extended shelf life and improved ability to place high quality fruit in the marketplace. | |
