Root variability among yellow lupin (Lupinus luteus L.) accessions grown at low temperatures in an undisturbed substrate

Abstract Root variation has become an important target for geneticists, ecologists, and breeders, given its direct influence on plant adaptation, resilience to climate change, and biomass and seed yields. However, the underground nature of roots has limited the assessment of root variability in plan...
