Defining populations of P. brassicae with near isogenic B. napus lines

Project Summary

Purpose

This study aims to develop a set of near isogenic B. napus lines containing single clubroot-resistance genes, and to define the populations of P. brassicae with the newly developed near isogenic lines.

Progress

Six near isogenic lines have been obtained, and further selection from other double-haploid lines will be resumed. Major pathotypes of P. brassicae have been classified into five clades.
