Abstract
White
lupin seed can be used for traditional and functional foods
or as animal feed. This study aimed to support lupin breeders and
production stakeholders by assessing the extent of genotypic, environmental,
and genotype × environment (GE) interaction effects on seed contents
of oil, tocopherols (TOC), and quinolizidine alkaloids (QA), grain
yield, and seed weight of eight elite genotypes grown in two climatically
contrasting Italian locations for two cropping years. On average,
plants in the subcontinental climate site exhibited higher grain yield
and seed size, about 8% lower oil content, and almost 85% higher QA
content than those in the Mediterranean climate site. The range of
genotype means was 2.97–5.14 t/ha for yield, 92–110
mg/g for oil, and 0.121–0.133 mg/g for TOC. TOC amount was
largely unpredictable and featured large GE interactions that hinder
its genetic improvement. Oil and alkaloid contents and seed size are
more predictable and offer potential for selection
