Development of Sugar Beet Hybrids Carrying Rhizomania Resistance Gene and Comparison of their Performance and Quality

Authors

Abstract

Crossing of pollinators and single crosses carrying RZ1 gene resulted in 44 sugar beet hybrids which were evaluated in infected fields in Fars and Khorasan. The seed of six diploid resistant pollinators and seven single crosses were first planted as parents in stekling field. After vernalization, parents were crossed in isolate tents, and hybrid seeds were harvested from female plants.The new hybrids along with resistant and susceptible checks were evaluated in infected condition during 2008-2009. According to the cluster analysis of the two year evaluation for yield, quality and disease severity index, the hybrids (7112*sb36)* 26388, (231*SB36)*26388, (436*SB36)*26388, (419*SB36)*27645, (231*SB36)*27645) and (419*SB36)*26388 were grouped with resistant checks. It seems that selection in the pollinators 26388 and 27645 will result in better hybrids
