Abstract
Two hundred and ninety-four accessions to the USDA world germplasm collection of Allium cepa were screened for resistance to Sclerotium cepivorum, the causal agent of white rot. The trial was conducted on organic muck soil in Burnaby, British Columbia, with uniformly high levels of added inoculum. Percent white rot infection in bulbs at harvest was measured and significant differences (P = 0.05) among the accessions occurred. High levels of resistance were found in at least three of the accessions, but none was immune.This publication has 0 references indexed in Scilit:
