Inheritance of Pigmentation and Pod Shape in Winged Bean (Psophocarpus Tetragonolobus)

Abstract

The inheritance of stem, calyx, corolla, pod, and pod wing colors, as well as cross-sectional pod shape was studied. Crosses were made between 16 accessions. The F1 and F2 data confirmed a previous report of the dominance of rectangular to flat pod shape. For the other characters, the results were Inconsistent with a simple one major gene difference as had previously been reported for stem, calyx, pod and pod wing color. A high, but variable, amount of outcrossing contributed to ambiguous results In the F2, and rendered genetic interpretation difficult.
