Abstract
Patterns of apparently homologous variation are to be seen over the whole range of pulse crops. These are most apparent in those pulses which originated from climbing, twining or trailing ancestors and have produced domesticates of erect growth form. The most remarkable homologous series can be seen in the genera Phaseolus (American) and Vigna (sens lat. i.e. including Asiatic Phaseolus spp.) The changes under domestication are typically loss of seed dormancy and pod dehiscence mechanisms, a change from perennial to the annual life form and a great change in seed size correlated with modified shoot architecture. Stems tend to be thicker, leaves larger, branches fewer, the number of nodes may be reduced and internode length is shortened. This process culminates in the evolution of self-supporting plants well-adapted to monocrop husbandry systems.
