Maize (Zea Mays L.) production has been greatly benefited from the improvement of inbred lines in regard to the resistance to diseases. However, the absence of resistant genotypes to bacteriosis is remarkable. The aim of the study was to identify genomic regions for resistance to Mal de Río Cuarto (MRC) and to bacterial disease (BD) in a diverse maize germplasm evaluated in the Argentinian region where MRC virus is endemic. A maize diverse population was assessed for both diseases during the 2019-2020 crop season. Incidence and severity of MRC and BD were estimated for each line and a genome wide association study (GWAS) was conducted with 78,376 SNP markers. A multi-trait mixed linear model was used for simultaneous evaluation of resistance to MRC and BD in the scored lines. The germplasm showed high genetic variability for both MRC and BD resistance. No significant genetic correlation was observed between the response to both diseases. Promising genomic regions for resistance to MRC and BD were identified and will be confirmed in further trials.

Barley Genotypes

In barley, semi-dwarf varieties are attractive for their superior harvest index and lodging resistance, but many semi-dwarf barley genotypes suffer from poor spike emergence. We performed a genetic characterization of a semi-dwarf line (ND23049) that combines short stature, strong stiff culms, and adequate spike emergence. We developed a doubled haploid (DH) population derived by crossing ND23049 and the cultivar CLE253. A subset of 88 DH lines and parents were characterized for plant height in 2013 and 2014 and genotyped. In total, 1984 SNPs (345 unique loci) were used to produce a linkage map of 1127.1 cM. Three QTLs for plant height were detected in this population and coincided with the HvGA20ox2/Sdw1, HvBRI1/Uzu1, and HvPRR95 gene loci. The phenotypic variation explained by each QTL was 75.8%, 7.7%, and 4.1%, respectively, and jointly explained 83.3% (2013) and 87.7% (2014) of plant height. Our results suggest that ND23049 contributed the “short” allele at the HvGA20ox2/sdw1 locus while CLE253 provided “short” alleles at the HvBRI1/uzu1 and HvPRR95 loci. We identified a large deletion (at least 92.7 Kb), including HvGA20ox2 (Sdw1), as the causal mutation in ND23049. A set of tightly flanked SNP markers will help breeders to develop improved semi-dwarf varieties.
