Genomic selection based on genotyping-by-sequencing (GBS) data could accelerate alfalfa yield gains, if it displayed moderate ability to predict parent breeding values. Its interest would be enhanced by predicting also for germplasm/reference populations other than those which was defined. Predicting accuracy may influenced statistical models, SNP calling procedures and missing imputation strategies. Landrace variety material from two genetically-contrasting reference populations, i.e., 124...
Genetic progress for forage quality has been poor in alfalfa (Medicago sativa L.), the most-grown legume worldwide. This study aimed at exploring opportunities marker-assisted selection (MAS) and genomic of traits based on breeding values parent plants. Some 154 genotypes from a broadly-based reference population were genotyped by genotyping-by-sequencing (GBS), phenotyped leaf-to-stem ratio, leaf stem contents protein, neutral detergent fiber (NDF) acid lignin (ADL), NDF digestibility after...
Peach was domesticated in China more than four millennia ago and from there it spread world-wide. Since the middle of last century, peach breeding programs have been very dynamic generating hundreds new commercial varieties, however, most cases such varieties derive a limited collection parental lines (founders). This is one reason for observed low levels variability gene pool, implying that knowledge extent distribution genetic critical to allow choice adequate parents confer enhanced...
In recent years, the use of genomic information in livestock species for genetic improvement, association studies and many other fields has become routine. order to accommodate different market requirements terms genotyping cost, manufacturers single nucleotide polymorphism (SNP) arrays, private companies international consortia have developed a large number arrays with content SNP density. The currently available differs among species: ranging from one goats more than ten cattle, is...
Peach (Prunus persica (L.) Batsch) is a major temperate fruit crop with an intense breeding activity. Breeding facilitated by knowledge of the inheritance key traits that are often quantitative nature. QTLs have traditionally been studied using phenotype single progeny (usually full-sib progeny) and correlation set markers covering its genome. This approach has allowed identification various genes but limited small numbers individuals used narrow transect variability analyzed. In this...
Highly polygenic traits such as fruit weight, sugar content and acidity strongly influence the agroeconomic value of peach varieties. Genomic Selection (GS) can accelerate yield quality gain if predictions show higher levels accuracy compared to phenotypic selection. The available IPSC 9K SNP array V1 allows standardized highly reliable genotyping, preparing ground for GS in peach. A repeatability model (multiple records per individual plant) genome-enabled eleven European populations is...
Terminal drought is the main stress that limits pea ( L.) grain yield in Mediterranean-climate regions. This study provides an unprecedented assessment of predictive ability genomic selection (GS) for under severe terminal using genotyping-by-sequencing (GBS) data. Additional aims were to assess GS different GBS data quality filters and models, comparing intrapopulation with interpopulation perform genome-wide association (GWAS) studies. The onset flowering 315 lines from three recombinant...
White lupin (Lupinus albus L.) is a valuable source of seed protein, carbohydrates and oil, but requires genetic improvement to attain its agronomic potential. This study aimed (i) develop new high-density consensus linkage map based on new, transcriptome-anchored markers; (ii) four important traits, namely, vernalization requirement, alkaloid content, resistance anthracnose Phomopsis stem blight; and, (iii) define regions synteny between the L. narrow-leafed (L. angustifolius genomes....
A thorough verification of the ability genomic selection (GS) to predict estimated breeding values for pea (Pisum sativum L.) grain yield is pending. Prediction different environments (inter-environment prediction) has key importance when target featuring high genotype × environment interaction (GEI). The interest GS would increase if it could display acceptable prediction accuracies in also germplasm that was not used model training (inter-population prediction). Some 306 genotypes...
Cultivar registration agencies typically require morphophysiological trait‐based distinctness of candidate cultivars. This requirement is difficult to achieve for cultivars major perennial forages because their genetic structure and ever‐increasing number registered material, leading possible rejection agronomically valuable study aimed explore the value molecular markers applied replicated bulked plants (three bulks 100 independent each per cultivar) assess alfalfa ( Medicago sativa L....
Abstract Deep learning is impacting many fields of data science with often spectacular results. However, its application to whole-genome predictions in plant and animal or human biology has been rather limited, mostly underwhelming While most works focus on exploring alternative network architectures, this study we propose an innovative representation marker genotype tested it against the GBLUP (Genomic BLUP) benchmark linear nonlinear phenotypes. From publicly available cattle SNP data,...
