    Production of improved self-incompatible lines of winter oilseed rape (Brassica napus L.) with convenient seed quality for hybrid breeding using of microspore culture technique

  • Original language description

    Doubled haploid (DH) regenerants were derived via improved microspore culture technique from crosses between the donor of ?00? quality OP 2051 (pollinator) and initial self-incompatible (SI) line Tandem 6/85 with high Glucosinolate (GSL) and erucic acidcontent in seed. The average GSL content in this set of regenerants was 84.68 &#956;mol/g of dry matter of seeds and the average erucic acid content was 22.84%. In the second cycle of quality improvement, two selected DH SI lines were crossed with donorsof quality (two breeding materials and two commercial cultivars). The percentage of obtained SI plants was 38.2%, i.e. 87 out of 228 derived fertile DH regenerants. 72 plants were selected for the detection of erucic acid content. The average erucic acid content in the set of DH regenerants was 14.20%. Nine plants with erucic acid lower than 2% were analyzed for glucosinolate content by high-pressure liquid chromatography (HPLC) method. Five out of the selected nine plants had GSL conte

    Produkce zlepšených autoinkompatibilních linií ozimé řepky (Brassica napus L.) s odpovídající kvalitou pro hybridní šlechtění pomocí techniky mikrosporových kultur

  • Czech description

    Dihaploidní regeneranty byly odvozeny pomocí zlepšené metody mikrosporových kultur z kříženců donorů kvality a autoinkompatibilních (AI) linií ve dvou cyklech zlepšovacího křížení. Byly získány rostliny, které nepřekračovaly limit 18 ?mol na gram semenepři 9% vlhkosti. Dihaploidní systém se ukázal jako použitelný pro zlepšení kvality AI genotypů.
