Unlike the situation in the major cereals, the yields of Vicia faba have
not been markedly increased during the last half century. There is no
single cause for this but among those that have been important is the
lack of cytogenetic understanding in relation to breeding performance.
Since as a consequence, little genetic variation has been available to
agronomists conclusions, probably unwarranted, have been drawn about the
limited prospects for the faba bean. Against such a background it has
been difficult to justify the investment of research resources in the
crop. The central theme of this book is that with the establishment of
cytogenetic studies in Vicia faba understanding of its genetic system
will develop in relation to breeding improvement and thereafter some at
least, of the impediments to yield increase can steadily though not
dramatically, be removed. We have distinguished between longer and
shorter papers and only the former include Abstracts. The latter amplify
themes in the longer papers or were written to develop particular topics
at the request of the editors. G.P. Chapman S.A. Tarawali Wye College,
