Title
Development of sugar beet hybrids carrying rhizomania resistance gene
Authors
Abstract
Crossing of pollinators and single crosses carring RZ1 gene resulted in 49 sugar beet hybrids which were evaluated in infected fields of Fars and Khorasan. The seed of six diploid resistant pollinators and seven single crosses were planted in steckling field. After vernalization, parents were crossed in isolatetents, and hybrid seeds harvested on female plants. The new hybrids along with resistant and susceptible checks were evaluated in natural infected conditions 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, (419×SB36)×26388 were grouped with resistant checks. It seems selection in the pollinators 26388 and 27645 will result in better hybrids.
