AB  - Given that the agronomic potential of <i>Lupinus angustifolius</i> is not yet known in Mexico, we evaluated the yield and chemical composition of six <i>L. angustifolius</i> varieties (Haags Blaue, Boregine, Borlu, Probor, Sonate, and Boruta) in Zapopan, Jalisco, Mexico. Studies were conducted during the Autumn-Winter seasons of 2012-2013. We identified the varieties with the highest and lowest protein concentrations and analyzed their respective amino acid profiles. The major protein constituents were determined by electrophoresis (SDS-PAGE). This experiment was conducted in an agricultural facility at the University of Guadalajara using a completely randomized block design and four replicates. The highest grain yield (kg/ha) was recorded on the Probor variety (4950 kg/ha) followed by Borlu (4940 kg/ha) and Sonate (4930 kg/ha). The Haags Blaue and Boruta varieties showed the lowest yields. There were considerable differences in seed protein content (P<0.05), with values ranging from 28.4 to 36.6% on Boruta and Probor, respectively. Analyses of amino acid composition showed that the Probor seeds had a higher concentration of lysine and methionine than Boruta (2.45 and 1.93 <i>versus</i> 1.09 and 1.63 g/100 g protein, respectively). Electrophoresis revealed prominent protein bands from 6 to 64 kDa for both varieties. The grain yield, chemical composition, and amino acid and protein concentrations of the tested varieties indicate that they could be successfully cultivated in the agricultural region of Zapopan, Jalisco, Mexico.
