Most recent advances in modern biotechnology in general and molecular markers in
particular have led to the development of a number of novel approaches that offer chance
of making plant breeding more efficient and cost effective. But, for efficient use in any
breeding program, potentially useful markers reported in genetic mapping studies should
be validated in regard to their effectiveness in determining the final phenotype in genetic
backgrounds relevant for breeders. The possible approaches are either to validate
markers in independent populations, such as different types of collections, or to validate
them in most important and relevant breeding material, such as advanced lines and cultivars.
Finally, the validation process should imply good quality, multi-year phenotypic
data obtained at site/s targeted by particular breeding program. This report discusses the
approaches and activities performed and the results obtained in last 8 years concerning
the validation of markers that could be useful for further improvement of the Novi Sad
wheat breeding program.
