Description
| - Uskutočnili sme prenos génu rezistencie Lr19 proti hrdzi pšenicovej do genotypov pšenice, kombináciou klasickej hybridizácie s postupmi selekcie pomocou markerov. Odroda Agrus so substitúciou chromozómu 7 Ag z Thinopyrum ponticum (= Agropyron elongatum,2n = 10x) a Sunnan s chromozomálnou translokáciou z Thinopyrum ponticum na chromozóme 7DL, v ktorých bola prítomnosť génu rezistencie Lr19 potvrdená, boli krížené s odrodami Sofia, Simona a Lívia. Z 5 kombinácií rodičov (Sofia x Agrus, Sofia x Sunnan, Simona x Agrus, Simona x Sunnan a Lívia x Agrus) bolo získaných 304 rastlín F2 generácie. Všetky rastliny boli analyzované na prítomnosť, resp. neprítomnosť nulovej alely Ep-D1c pomocou izoelektrickej fokusácie endopetidáz extrahovaných z listových segmentov. Prítomnosť alely Ep-Dlc, biochemický marker génu rezistencie Lr19 proti hrdzi pšenicovej, bola zistená v 49 rastlinách. Segregácia alely v potomstve poukazuje na zníženie prenosu génu rezistencie Lr19 peľom z odrod Agrus a Sunnan do potomstiev. Poto (cs)
- Cultivar Agrus, possessing a chromosoal substitution and cultivar Sunnan, possessing a translocation from Thinopyrum ponticum with leaf rust resistance gene Lr19 agains Puccinia triticina, were crossed with the susceptible winter wheat cultiwar Sofia, Simon a Livia to transfer Lr19 into agronomically better genotypes by marker-assisted selection.
