| Summary: | Conventional plant breeding use morphological and phenotypic markers for the identification of important agronomic traits. Plant breeders and scientists continuously seek to develop new techniques, which can be used for faster and more accurate introgression of desirable traits into plants. Over the last several years there has been significant increase in the application of molecular markers in the breeding programmes of different species. So far, detected level of polymorphism and informatitivnes of different molecular marker methods applied in MAS (Marker Assisted Selection) studies (RFLP, AFLP, etc.) were insufficient either to validate their further use or there were very expensive and of huge healthy risk. Fortunately for wheat (and other crops) breeders, the new class of molecular markers - microsatellites have prove recently to be most powerful for MAS. But, due to lack of the knowledge, experience, valid informations and even tradition and habits, many breeders have either negative or repulsive attitude towards implementation of MAS in breeding programes. In this paper the relevant facts regarding implementation of MAS in breeding are discussed in general, and for wheat breeding in particular, in order to summarize merits and limitations in application of microsatellites in MAS selection. . |
