dc.description.abstract | Genetic variability of locally adapted Serbian and Austrian winter wheat varieties was evaluated
in order to assess their potential as a genetic material that can be exploited in crosses between
two different European breeding pools. A field trial with 20 elite wheat varieties from each
country was set at the Institute of Field and Vegetable Crops, Novi Sad, Serbia in a row-column
design with three replications during the 2016/2017 season. The genotypes were phenotyped
for tillering, heading and flowering time, plant height, ear length, number of spikelets per spike,
number of grains per spike, thousand-kernel weight, chlorophyll content and resistance to
prevalent wheat diseases. Additionally, the varieties were genotyped with 30 microsatellites.
The varieties from two geographic regions and different release periods were clearly
differentiated with population structure obtained from marker data. A significant phenotypic
variation was found for most of the traits. Coefficients of variation were the largest for
chlorophyll content (16.5%) and plant height (10.1%). Generally, the early genotypes were
more susceptible to leaf rust (r = -0.6), while the late maturing genotypes produced more grains
per spike (r = 0.4). The Serbian varieties had earlier tillering (p < 0.03), heading (p < 0.00) and
flowering (p < 0.00) dates, shorter plant stems (p < 0.00), higher chlorophyll content (p < 0.00)
and were more susceptible to leaf rust (p < 0.00) than the Austrian ones. The principal
component analysis indicated general properties of the groups that would facilitate the choice
of parent combinations for crossings. | sr |
