Resistance in Broccoli to Bacterial Soft Rot Caused by<i>Pseudomonas marginalis</i>and Fluorescent<i>Pseudomonas</i>Species

Abstract

Significant differences in susceptibility of brocoli (Brassica oleracea var. italica) genotypes to bacterial soft rot (heat rot), caused by Pseudomonas marginalis (P. fluorescens biovar II) and other fluorescent Pseudomonas spp., were observed in four field studies from 1986 to 1989. Cultivars Green Defender and Shogun consistently appeared highly resistant to bacterial soft rot. High disease resistance was observed in 1989 in experimental line NVH 521 (...)
