Sažetak
Pre-harvest sprouting (PHS) in wheat can cause a reduction in grain yield, test weight and grain quality. The level of seed dormancy at harvest maturity is the main component of PHS resistance in wheat. In the present study, recombinant inbred line (RIL) mapping population developed by single seed descent from the cross ‘Bezostaja 1’ (weak PHS resistance, non-dormant) × ‘Klara’ (high PHS resistance, dormant) was used to analyse seed dormancy. The RIL population and parental genotypes were grown in replicated trials in two different environments. The genetic and the genotype × environment component of variance accounted for 71 and 20% of the phenotypic variance for seed dormancy, respectively. The estimated heritability of the trait was 0.85. In the RIL population, transgressive segregation was observed mostly in the direction of low seed dormancy, while only a few lines had more pronounced seed dormancy than the dormant parent ‘Klara’. A genetic map has been developed based on the RIL population while QTL analysis using composite interval mapping (CIM) and multiple interval mapping (MIM) allowed the identification of putative quantitative trait loci (QTLs) controlling seed dormancy.
