| Description
| - Doubled haploid (DH) self-incompatible (SI) regenerants with improved seed quality were derived after two improvement crossing cycles with different ''00” quality donors. The original genetic resource of recessive sporophytic SI was characterised by a high glucosinolate (GSL) and erucic acid content. SI regenerants of satisfactory seed quality parameters were obtained from the second cycle of crossing. Total number of derived SI plants was 87, i.e. 38.2% out of 228 obtained fertile doubled haploid regenerants developed in 2004. Nine plants out of the analysed 45 SI DH regenerants had the erucic acid content lower than 2%. Five out of these nine plants, which were analysed by HPLC method, had the glucosinolate content lower than the limit 18 µmol/g at 9% seed moisture. The method based on the spraying of inflorescences with 5% NaCl to enable reproduction of SI lines was verified.

- Z výchozích genetických zdrojů recesivní sporofytické autoinkompatibility (AI) u řepky ozimé byly po dvou cyklech zlepšovacího křížení s různými donory 00 kvality odvozeny dihaploidní (DH) autoinkompatibilní regeneranty z mikrosporových kultur. Výchozí genetický zdroj AI se vyznačoval vysokým obsahem glukosinolátů (GSL) a kyseliny erukové v semeni. Po druhém cyklu křížení byly získány AI regeneranty s vyhovující 00 kvalitou. Celkový počet odvozených AI regenerantů byl 87 (38,2 %) z 228 fertilních dihaploidních regenerantů. Z analyzovaného souboru 45 AI DH regenerantů, vytvořených v roce 2004, mělo 9 rostlin obsah kyseliny erukové do 2 %. Analýza GSL metodou HPLC prokázala u pěti z těchto rostlin obsah GSL nižší než limit 18 µmol/g semene při 9% vlhkosti. Byla též ověřena praktická použitelnost metody produkce semen AI linií postřikem 5% roztoku NaCl v podmínkách technické izolace. (cs)
