Evaluation of Lupinus albus L. germplasm for the southeastern USA.

Crop Science, September, 2005 by Noffsinger, Steven L.; van Santen, Edzard

While white lupin (Lupinus albus L.) has potential as a new minor winter crop, adapted germplasm have to be discovered and considerations for cold tolerance, pest resistance, and other traits determined. We evaluated 100 accessions in 1990-1991 and 616 in 1991-1992 at two locations in central Alabama, USA. Twenty-four seeds per accession were hand sown in an upland area on a Marvyn sandy loam (fine-loamy, kaolinitic, thermic, Typic Kahapludults) and in a river bottom area on a Wickham fine sandy loam (clayey, kaolinitic, thermic, Typic Rhododults). Backward stepwise and canonical discriminate analysis (CDA) was used to determine which agronomic traits and groups of accessions were most important for adaptation. Accessions were selected for further evaluation and breeding on the...
