Association of fusarium wilt susceptibility with clubroot resistance derived from winter Brassica napus L. ‘Mendel’

Figures & data

Table 1. Segregation for clubroot and fusarium wilt resistance in a doubled haploid (DH) population derived from a cross between a clubroot susceptible (CS) fusarium wilt resistant (FWR) Brassica napus line and a clubroot resistant (CR) fusarium wilt susceptible (FWS) B. napus line, and tested in greenhouse and growth chamber experiments.

CR		CS		CR: CS 1:1		FWR: FWS 1:1		Independent assortment 1:1:1:1

Clubroot and fusarium wilt resistance in a doubled haploid (DH) and different advanced generation populations, derived from cross between clubroot susceptible (CS) fusarium wilt resistant (FWR) Brassica napus and clubroot resistant (CR) fusarium wilt susceptible (FWS) B. napus lines, tested in greenhouse (GH) and field plots.
