Abstract Selection for multiple traits is a highly challenging task breeders due to potential unfavorable associations between characters. Fusarium head blight FHB, being one of the most relevant diseases affecting durum wheat frequently shows in this respect an correlation with morpho-agronomical like plant height (PH) and heading date (HD). In study, we used cross-validation scheme assess prediction ability genomic predictions (GP) FHB severity relying on best linear unbiased models...
FHB resistance of durum wheat was improved by introgression Fhb1 and genes from emmer selection against adverse alleles elite wheat. Durum is particularly susceptible to Fusarium head blight (FHB) breeding for impeded the low genetic variation within gene pool. To extend basis in wheat, we analyzed 603 lines crosses with donors carrying derived Triticum aestivum, T. dicoccum dicoccoides. The were phenotyped resistance, anthesis date, plant height artificially inoculated disease nurseries...
Environmental factors like temperature and humidity are presumed to greatly influence Fusarium head blight FHB infections in wheat. Anther retention AR, on the other hand, is a morphologically neutral trait that shares common genetic basis with resistance. In this study, our aims were to: (i) Evaluate two types of corrections severity scores, namely method-1 via linear regression flowering time (FT), method-2 best-subset multiple analysis comprising FT plus accumulated thermal variables;...
Resistance to Fusarium head blight (FHB) of spelt wheat was investigated in field trials carried out at three European locations between 2016 and 2018. assessed after artificial inoculation by visual scoring symptoms the determination contamination grains glumes with mycotoxin deoxynivalenol (DON). It found that typical traits such as tall plant height, lax spikes, tough play a role passive resistance factors. Across all test environments, modern varieties significantly reduced height showed...
Abstract Creating new genetic variation by crossing two or more parents is the initial and often most important step when developing crop varieties. Hence, several mate selection indices have been suggested to support planning of crosses in genomic breeding pipelines that established many programmes recent years. The corresponding index weights are however difficult determine objectively, these feature determined laborious grid searches rules thumb. aim this study was compare methods employ...
Abstract Genomic selection (GS) has revolutionized breeding practices by integrating genotype and phenotype data to predict genomic estimated values (GEBVs), offering the potential accelerate cycles intensify enhance early-stage selections. This approach relies on concept of linkage disequilibrium (LD) between genetic markers quantitative trait loci (QTL) within populations. LD is non-random association alleles at different provides valuable insights into recombination rates. study aimed...
