Maize Research Institute „Zemun Polje“ (MRIZP) gene bank preserves ex-situ an
active collection (5806 accessions), thus ranking among the five largest European
national maize gene bank collections. Local (i.e. western Balkan) maize landraces
(2217 accessions) are considered to be the most significant genotypes, since they
represent the original biological material created by the process of natural selection
and adapted to local growth conditions, thus offering the great opportunities for
different breeding purposes and contributing to yield increase. Currently, they are
not directly used in breeding, but rather for development of synthetic populations or
core collections for the traits of interest, allowing the integration of the most valuable
traits (adaptability, variability, divergence and heterotic potential). In the last 15
years, in MRIZP gene bank was conducted identification of superior genotypes
regarding specific traits (cytoplasmatic male sterility) and abiotic st...ress tolerance
(herbicides tolerance). In response to more frequent unpredictable and extreme
climatic events, as well as to growing demand for healthy food and feed, in MRIZP
gene bank were established drought tolerant and improved quality core collections
through implementation of long-term pre-breeding programmes, as the most
promising way of linking genetic resources and commercial breeding programmes.
Moreover, exchange of maize inbred lines from MRIZP gene bank and Agricultural
Institute Osijek working collections, genotyping and phenotyping of inbreds, and
statistical analysis of molecular and agronomic data, is conducted through ongoing
Project “Harmonization of methods for phenotyping, genotyping and management
of genetic resources in maize”. Joint analysis of genetic diversity originated from the
Western Balkan Corn Belt, along with comparative analysis with the same standards
(available genome sequencing data of public lines), will enable the determination of
heterotic pattern, removal of possible duplicate and redundant accessions from the
collections, contributing to a more efficient management of large inbred lines
collections.
