Hybrid breeding in barley ( L.) offers great opportunities to accelerate the rate of genetic improvement and boost yield stability. A crucial requirement consists efficient selection superior hybrid combinations. We used comprehensive phenotypic genomic data from a commercial program with goal examining potential predict performances. The were comprised replicated grain trials for 385 two-way 408 three-way hybrids evaluated up 47 environments. parental lines genotyped using 3k single...
Background: The expected genetic variance is an important criterion for the selection of crossing partners which will produce superior combinations genotypes in their progeny. advent molecular markers has opened up new vistas obtaining precise predictors a cross, but fast prediction methods that allow plant breeders to select based on already available data from breeding programs without complicated calculations or simulation populations are still lacking. main objective present study was...
Abstract Background Calluna vulgaris is one of the most important landscaping plants produced in Germany. Its enormous economic success due to prolonged flower attractiveness mutants morphology, so-called bud-bloomers. In this study, we present first genetic linkage map C. which mapped a locus economically highly desired trait “flower type”. Results The was constructed JoinMap 4.1. using 535 AFLP markers from single mapping population. A large fraction (40%) showed distorted segregation. To...
Predicting the grain yield performance of three‐way hybrids is challenging. Three‐way crosses are relevant for hybrid breeding in barley ( Hordeum vulgare L.) and maize Zea mays adapted to East Africa. The main goal our study was implement evaluate genome‐wide prediction approaches using data single‐cross a scenario which parental lines originate from three genetically distinct subpopulations. We extended ridge regression best linear unbiased (RRBLUP) devised genomic selection model allowing...
Abstract Hybrid breeding of wheat ( Triticum aestivum L.) is limited by its self‐pollinating nature. Past cross‐pollination improvements mostly focused on optimizing male traits. We tested the hybrid seed yield 100 diverse elite lines treated with a chemical hybridization agent (CHA) and pollinated non‐sterilized plants in multi‐environmental field trials. Plant height phenological traits female were also assessed. In parallel, control experiments without CHA sterilization conducted to...
<title>Abstract</title> Wheat is one of the most important staple crops playing a pivotal role to sustainably feed growing world population. breeding mainly focused on improving agronomy and techno-functionality for bread or pasta production, but nutrient content becoming increasingly more fight malnutrition. We therefore investigated 282 wheat cultivars from seven decades in Central Europe 63 different traits related agronomy, quality nutrients under multiple field trials. has tremendously...
Results on our investigations the genetics and molecular biology of two major characters, self-incompatibility floral scent will be presented. In crosses between diploid R. multiflora hybrids, pattern inheritance double flowers was often found to dependent direction cross. Genetic experiments involving backcrosses individual progeny both parents indicated segregation alleles as predicted for a gametophytic SI-system. First data S-locus The second characteristic, roses is very complex due...
Abstract Broadening the genetic base of elite breeding programmes is crucial for further success. The absence major adaption genes, however, often masks grain yield value resources. We assessed ability a hybrid strategy to provide unbiased performance estimates 21 barley By crossing them tester lines, 25 three‐way hybrids were produced and evaluated together with part their parents eight important agronomic traits in replicated field trials four environments. phenotypic data analyses...
Genomic prediction has been established in breeding programs to predict the genotypic values of selection candidates without phenotypic data. First results wheat showed that genomic predictions can also prove useful select among material for which data are available. In such a scenario, evaluated with low intensity field. Genome-wide effects estimated from field and then used candidates. The objectives our simulation study were investigate correlations r ( y, g ) between y compare these p, p...
Abstract The nature and effect of mutations are fundamental importance to the evolutionary process. generation with mutagens has also played important roles in genetics. Applications include dissecting genetic basis trait variation, inducing desirable traits crops, understanding load. Previous studies sodium azide-induced have reported single nucleotide variants (SNVs) found individual genes. To characterize induced by azide, we analyze whole-genome sequencing (WGS) 11 barley lines derived...
