A novel sunflower broomrape race with unusual virulence potentially caused by a mutation.

ABSTRACT:

Introduction

The sunflower broomrape (Orobanche cumana Wallr.) gene pools of the Guadalquivir Valley and Cuenca province in Spain had predominantly race-F virulence. A new race G was observed recently in the Guadalquivir Valley potentially due to the genetic recombination of the avirulence genes of both gene pools.

Methods

In this research, we have studied populations with atypical virulence from Cuenca. These populations parasitize on DEB2 sunflower line, resistant to all race-G populations evaluated. Ten populations collected in Cuenca province were evaluated with sunflower differential lines and genotyped with 67 SNP markers.

Results

Although genetic recombination with individuals of the Guadalquivir Valley gene pool has been observed in most populations, re
