Chromosome substitutions with dominant loci Vrn-1 and their effect on developmental stages of wheat

Original language description

The effect of wheat homoeologous group 5 chromosome substitutions with dominant alleles Vrn-A1, Vrn-B1, and Vrn-D1 on growth stages was analysed within a set of substitution lines Zdar (Zl 5A), Zdar (CP 5B), Zdar (CS5D), Koutka (Zl 5A), Koutka (âP 5B), Koutka (CS5D). The substitution lines were sown into the field plots on ten subsequent sowing dates. The results showed marked differences between the early and late sowings (mostly negative effect) that were mostly connected with the response to day length, expressed by the contrasting photoperiod sensitivity of the genetic backgrounds of Zdar and Koutka. The largest differences between early and late sowing were found in the lines carrying the chromosome 5D (Vrn-D1) while the substitution lines for chromosome 5A were the least sensitive possibly due to the epistatic effect of the present Vrn-A1 locus, suggesting the most marked effect of present Vrn-1 loci on vernalisation response.

Czech description

Ucinek substituci chromosomu 5. homoeologicke skupiny, nesoucimi dominantni alely Vrn-A1, Vrn-B1, and Vrn-D1, na rustova stadia byl analyzovan u souboru substitucnich linii Zdar (Zl 5A), Zdar (CP 5B), Zdar (CS5D), Kosutka(Zl 5A), Kosutka (CP 5B), Kosutka(CS5D). Zrna substitucnich linii byla vyseta na pokusna policka po tydnu v deseti nasledujicich terminech.Vysledky prokazaly vyrazne rozdily mezi ranym a pozdnim datem vysevu (prevazne negativni efekt), ktery byl vetsinou ve vztahu k delce dne, jak bylovyjadreno kontrastni fotoperiodickou citlivosti genetickych pozadi rodicovskych odrud Zdar a Kosutka. Nejvetsi rozdily mezi ranymi a pozdnimi vysevy byl nalezen mezi liniemi nesoucimi chromosom 5D (Vrn-D1), zatimco substitucni linie s chromosomem 5A byly nejmene citlive pravdepodobne diky epistatickemu ucinku pritomneho lokusu Vrn-A1. To ukazuje na jeho nejvyraznejsi ucinek mezi porovnavanymi lokusy Vrn-1 ja jarovizacni pozadavek. (Pánková K., Kosner J.)
