Genetic diversity and trait genomic prediction in a pea diversity panel

Abstract: BackgroundPea (Pisum sativum L.), a major pulse crop grown for its protein-rich seeds, is an important component of agroecological cropping systems in diverse regions of the world. New breeding challenges imposed by global climate change and new regulations urge pea breeders to undertake more efficient methods of selection and better take advantage of the large genetic diversity present in the Pisum sativum genepool. Diversity studies conducted so far in pea used Simple Sequence Repeat (SSR) and Retrotransposo… Show more

“…Diversity and population structure analysis using mapped markers suggested the presence of two different groups whereas no significant impact of population structure on prediction accuracy was observed. Our results were in complete accordance with results obtained in GS study on pea (Burstin et al, 2015). …”

“…Further higher prediction accuracies could be the design of the study in such a manner that training set as well as testing set were phenotyped in same environment (Burstin et al, 2015). Diversity and population structure analysis using mapped markers suggested the presence of two different groups whereas no significant impact of population structure on prediction accuracy was observed.…”

“…Detecting and taking account of many relevant small-effect QTL will only be possible by using high numbers of markers, as foreseen through the development of next-generation sequencing approaches for this crop based on SNP Array technology (Deulvot et al 2010;Burstin et al 2015). The adoption of GenoPea 13.2K SNP Array recently exhibited high genome-enabled predicting ability for traits such as thousand seed weight and flowering time (Tayeh et al 2015), Genotyping-by-sequencing procedures (Elshire et al 2011) may prove an alternative, possibly less expensive approach to the genomic prediction of quantitative traits, as indicated by preliminary results of grain yield prediction in different cropping environments for material that is largely coincident with that included in this study (Annicchiarico et al, unpublished data).…”
