Hybrid breeding of winter oilseed rape by utilization of self-incompatibility and cytoplasmic male sterility systems

Original language description

Three self-sterility systems including self-incompatibility (SI), cytoplasmic male sterility (CMS) Ogu-INRA and Shaan 2A are used for breeding of domestic rapeseed hybrids. The original self-incompatible lines developed from older European cultivars of rapeseed were characterized by a high glucosinolate (GSL) and erucic acid content. SI lines with improved seed quality have been developed by crossing of original SI materials with donors of double zero quality and subsequent deriving of doubled haploids(DH). Molecular markers based on PCR analyse of SLG gene have been developed for screening of self-incompatible genotypes. Comparison of seed test and molecular analysis of microspore regenerants for detection of SI and SC genotypes showed the possibility to discard majority of self-compatible plants in the early stage of development. Two different CMS systems are also used in breeding of hybrid cultivars. In Ogu-INRA CMS initial material obtained from France and Shaan 2A CMS from China,

Hybridní šlechtění ozimé řepky s využitím autoinkompatibility a cytoplazmatické samčí sterility

Czech description

Pro šlechtění domácích hybridů ozimé řepky jsou využívány tři systémy autosterility: autoinkompatibilita (AI), CMS Ogu-INRA a CMS Shaan 2A. Výchozí AI linie se vyznačovaly vysokým obsahem glukosinolátů a kyseliny erukové. Zlepšení kvality semen bylo dosaženo křížením s donory 00 kvality a následným odvozením dihaploidů (DH). Byly ověřeny molekulární markery pro skríning AI genotypů. Pomocí využití dihaploidů byly vytvořeny mateřské sterilní linie a linie s obnovou fertility se zlepšenou kvalitou semen pro oba systémy CMS.
