Die Züchtung von vollkommen alkaloidfreien Süßlupinen, die sich zur Herstellung von menschlichen Nahrungsmitteln eignen

Mutations and Crop Improvement. Ii. The Genus Lupinus (Leguminosae)

“…Alkaloid content is too high for considering the sweet lupines suited for human consumption (note in this connection their high pro-tein content and the superior digestibility of lupine protein). However, KLAWITTER andSENGBUSCH (1943) (v. also HACKBARTH andTROLL, 1959, p. 20) have attained some improvement in this respect by means of gene recombination. The "double recessive yellow Muncheberger strain" contains both the recessive genes dulcis and liber (together with invulnerabilis, niveus and w for soft seed-coats) .…”

Broadening the bases for the breeding of yellow sweet lupine

“…An attempt is being made to find types with a still lower alkaloid content than in line 102, using the method of KLA-WITTER and VON SENGBUSCH (6). It is expected that the combinations aadd, aall and drill, to be obtained by crossing, will contain so few alkaloids that they are suitable for human consumption.…”
