Grasspea and chicklings (Lathyrus L.)

Abstract

The genetic diversity of the genus Lathyrus is of immense significance, particularly for rain-fed cropping systems of many countries (Campbell et al., 1994) as a resource for the improvement ofL. sativus L., but also because the genus is largely under-utilised. Several species are cultivated for food, feed, and fodder, as well as for ornamental purposes (Sarker et al., 1997), but there is potential for further exploitation of the Lathyrus gene pool. Therefore, the collection, conservation, characterization, study of genetic diversity and utilization of the genus Lathyrus is a priority. There is an urgent need actively conserve the genetic diversity of the genus using both ex-situ (gene banks) and in-situ (natural habitats) techniques. This will permit a critical assessment to be made of the genetic diversity, evolution and genetic erosion of the genus, as well as greatly enhancing further exploitation (Sabanci, 1996).
