Variety traits

Determinacy — Yellow Lupine

Lupinus luteus L.

This trait is characterized by a reduction in sympodial branching, where the formation of lateral shoots is blocked or restricted. Genetically, determinacy in this crop is often controlled by the recessive sbr gene.

In the reference 5 varieties crop Yellow lupin, where this is mentioned in the description.

In yellow lupine, determinacy manifests as an alteration in plant architecture through the suppression of lateral shoot development. In breeding practice, the degree of this trait's expression is assessed by the number of primary and subsequent order lateral branches, although there are no clear, standardized quantitative units of measurement.

This trait directly influences the developmental biology of the crop, ensuring earlier and more uniform seed ripening by concentrating plant resources on the main stem. This contributes to improved efficiency in mechanical harvesting and greater uniformity of seed material, though it is often accompanied by a reduction in overall yield compared to branched forms.
