"Natural cross-pollination in pigeonpea, mediated by insects, is a universal phenomenon with the first report appearing in\r\n1919. Considerable information is now available on various aspects of this biological phenomenon including degree of\r\nout-crossing and pollinating agents in different parts of the world. A large variation (0-60%) has been recorded in 30\r\ndifferent environments across 11 countries. The role of cross-pollination in rapid deterioration of the genetic purity of\r\ncultivars and elite genetic stocks is well understood and documented by breeders and seed producers. Pigeonpea breeders\r\nhave converted this constraint into an opportunity by way of visually selecting natural hybrids from landraces in farmers’\r\nfields and deriving high yielding cultivars. In a key development, the occurrence of natural cross-pollination in the wild\r\nrelatives of pigeonpea has also been recorded; and in three wild species such natural hybrids have yielded valuable\r\ncytoplasmic male sterility systems. This has encouraged breeders to develop a hybrid breeding technology with natural\r\nout-crossing playing a key role in the large-scale seed production of commercial pigeonpea hybrids."^^ .
