Quality of Lupinus albus L. (White Lupin) Seed : Extent of Genotypic and Environmental Effects / P. Annicchiarico, P. Manunza, A. Arnoldi, G. Boschin. - In: JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY. - ISSN 0021-8561. - 62:28(2014 Jul 16), pp. 6539-6545. [10.1021/jf405615k]
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.
