Molecular markers for study of oilseed rape (Brassica napus L.). II. The review of markers used for breeding programs
Języki publikacji
Konkurencja na rynku nasion wymusza na hodowcach rzepaku znaczne przyspieszenie prac mających na celu uzyskiwanie nowych lepszych odmian o różnych cechach. Aby sprostać takim wyzwaniom niezbędne jest zastosowanie nowych metod wykorzystujących markery molekularne. W pracy wskazano na korzyści i trudności związane z ich stosowaniem w hodowli rzepaku oraz omówiono potencjał wybranych technik dla praktycznych zastosowań. Opisano podstawowe strategie badawcze, które pozwalają na wyszukanie markerów sprzężonych z określonymi cechami. Omówiono także metody poszukiwania markerów poprzez analizę całego genomu, które mają istotne znaczenie dla analizy cech wielogenowych. Na koniec podano liczne przykłady praktycznych zastosowań markerów molekularnych w hodowli rzepaku wspomaganej markerami molekularnymi (MAS), jak również przykłady innych zastosowań użytecznych dla hodowli tej rośliny.
To withstand the present competition on the seed market, the breeders must speed up their efforts to obtain new varieties better in various characteristics. It is hard to cope with such a challenge without using new methods, including the use of molecular markers. Both advantages and difficulties related to these methods as well as their usability in rapeseed breeding are presented here. Basic strategies of searching for molecular markers linked with selected traits of plants are described. The article includes some remarks on the analysis of the whole genome, which is the method of choice in case when the markers linked with multigenic features are to be found. Finally, the review of markers used for marker assisted selection (MAS) and other applications of these techniques in oilseed rape breeding programs are presented.
