Introgression of Resistance to Multiple Pathotypes of Plasmodiophora brassicae from Turnip (Brassica rapa ssp. rapifera) into Spring B. napus Canola

Clubroot disease resistance has been introgressed from Brassica rapa into canola following different approaches including a B. napus × interspecific cross; however, the details of this cross are not available. To extend our knowledge for introgression to multiple pathotypes, we crossed clubroot-resistant turnip with susceptible and backcrossed F1′s canola. The backcross population was subjected pedigree breeding selection clubroot canola-quality traits; pathotype 3H 3A performed in early advanced generations, respectively. generation lines were also evaluated 3H, 3A, 2B, 5x, field clubroot, agronomic seed quality traits. Following this, developed carrying pathotypes nuclear DNA content similar napus. Resistance showed weak correlation other whereas strong positive 5x indicating that these under genetic control. Thus, results demonstrate can be even when single is generations.
