The possibility of using Shaan 2A cytoplasmic male sterility (CMS) system for breeding domestic rapeseed hybrids was verified. Three reliable male sterile lines with low glucosinolate (GSL) content were derived from the original high GSL Chinese materials by six times repeated backcrossing with donors of 00 characters. Four relevant fertility restorers (Rf) were also improved by means of crossing with quality donors and additional development of doubled haploids (DH). The experimental three-way hybrids were produced using CMS lines crossed with the cultivar Californium as the sterile mother components and subsequently with DH Rf lines. The yield and agronomic performance of the five hybrids tested in three-location trials were comparable with high performance line and hybrid cultivars.
