An integrated and comparative view of pea genetic and cytogenetic maps

SummaryMolecular marker maps have been generated for pea (Pisum sativum), but these have not been well integrated with previous genetic and cytogenetic maps. Here, these data sets are brought together to summarize the current state of knowledge, exploiting the common genetic markers used in many different studies. The pea linkage map was known to be simply related to the maps of lentil and chickpea, and these relationships are presented in the context of the present map. The genomes of these legumes are interpreted as having an equivalent gene content, but differing in their repetitive DNAs.
