‘Polima’ cytoplasmic male sterility (CMS) was transferred to three different genotypes of B. napus i.e. GSL‐1, ISN706 and HNS‐8 by repeated backcrossing and was found to be completely stable in the nuclear background of synthetic B. napus genotype, ISN706, derived from a cross B. campestris ssp. oleifera var. brown sarson × B. oleracea var. botrytis cv. Tusa Katki'. The BC 5 and BC 6 generation lines of ISN706, GSL‐1 and HNS‐8 with ‘Polima’ CMS were grown under a range of temperature and photo‐period conditions to test their stability. No breakdown in sterility was observed in ‘Polima’ ISN706 and, therefore, this genotype can be used as a maintainer for hybrid seed production.
