Summary

A mutant pigeon pea, showing dwarf and bushy growth, very late maturity, poor yield and abnormal flowers was isolated from the tall variety, Brazil P/2. It is proposed that the mutant be called ‘dwarf’.

A single recessive gene appears to be responsible for dwarfness and seems to have pleiotropic effect on maturation. The symbol proposed for the dwarfness gene is ‘d’.

Zusammenfassung

Aus einer hochwüchsigen Straucherbse (Cajanus cajan (L.) Millsp.) der Sorte Brazil P/2 wurde eine Mutante mit verzwergtem und buschigem Wuchstyp, sehr später Reife, geringer Ertragsfähigkeit und abweichender Blütenform isoliert, für die der Name „dwarf“ vorgeschlagen wird.

Nur ein rezessives Gen scheint für den Zwergwuchs verantwortlich zu sein, das einen pleiotropen Effekt auf die Reife ausübt. Für dieses Gen wird das Symbol „d“ vorgeschlagen.
