Andean lupine seeds were studied to establish the effect of moisture, temp., plant genotype and sowing date on amino acid and protein content, contents of methionine, valine and aspartic acid. The epigonal genotype of lupine contained more of methionine and valine than the semiepigonal one. The shift in sowing date resulted in a decrease in content on the amino acids. The epigonal plants contained more glutamic acid than the semiepigonal ones. Delaying the sowing date enhanced accumulation of glutamic acid. No significant effect of the conditions was obsd. for protein content.
