Summary

From three sets of crosses involving the phenotypes chocolate, red oxide, green with chocolate streaks and green with red oxide streaks, the action of the genes governing the phenotypes of the pods ofCajanus cajan (L.) Millsp. has been proposed. GeneL controls production of chocolate colour,L r an allelomorph ofL hitherto unreported, controls production of red oxide colour and geneD controls distribution of this colour. As regards inheritance of these two genes, the relationships betweenL andL r isL>L r andD is incompletely dominant overd. The genotypes of the different phenotypes have been presented.

Zusammenfassung

An drei Kreuzungsreihen von Sorten unterschiedlicher Hülsenfarbe (schokoladenbraun, rostrot, grün mit schokoladenbraunen Streifen und grün mit rostroten Streifen) wurde die Vererbung dieses Merkmals bei der Straucherbse (Cajanus cajan (L.) Millsp.) untersucht. Für das Auftreten der schokoladenbraunen Hülsenfarbe ist das GenL verantwortlich,L r, ein bisher unbekanntes Allelomorph vonL, für die rostrote Farbe, während das GenD die Verteilung der Farbe steuert.L ist vollständig dominant überL r undD unvollständig dominant überd. Auf Grund der gemachten Feststellungen werden die Genotypen für die einzelnen Phänotypen angegeben.
