Genetic variation and genome-enabled selection of white lupin for key seed quality traits.

ABSTRACT:

Background

White lupin (Lupinus albus L.) requires selection for low quinolizidine alkaloid (QA) content and other seed quality traits to become an important high-protein crop. There is limited information on trait variation, genetic architecture, genotype × environment interaction (GEI), relevant genomic areas, and opportunities for genomic selection (GS).

Results

A reference population of sweet-seed breeding lines possessing the pauper locus underwent multi-year evaluation for seed weight, protein content and oil content in two regions (Italy and Chile) and evaluation for content of 13 QAs by a gas chromatography-mass spectrometry method in Italy. A second population including landrace genotypes of worldwide origin was evaluated for protein and oil content and seed weight
