Anthocyanin stem pigmentation, silver leaflet midrib, leaflet hirsuteness, presence of long hairs on the calyx lobes, black pod colour, speckled seed testa and twining stem habit all appeared to be conditioned by single completely dominant gene action, as was apparent resistance to powdery mildew. Width of the floral standard, peduncle length, number of seeds per pod, weight of 100 seeds, tuberous root dry weight, total plant dry weight and harvest indices for seed and tuberous roots all appeared to be quantitatively inherited, with moderate broad sense heritabilities. No difficulties were encountered in obtaining F1 and backcross progenies in any crosses. Further, the inheritance of traits in progeny of Australian x African crosses appeared normal and, in the several instances where direct comparison was possible, similar to that observed in crosses within the Australian material.
