PREFACE
In 1978 the first edition of our book ' 'Application of Mutation Breeding Methods
in the Improvement of Vegetatively Propagated Crops" appeared. It found general
acceptance. Most readers and reviewers especially valued the extensive coverage of
the literature in the chapters dealing with the different crops. This is also reflected
by the many times that our work has been referred to in other publications.
When early in 1985 the first edition of the book became practically sold out, it
was considered whether a second edition would be worthwhile and, if so, what
changes should be made. It was agreed with the publishers that in the first place the
book should be updated for crops by adding new and relevant references and by cor-
recting apparent omissions and mistakes. We should like to acknowledge here the
contribution of several users of this book. In addition, as some readers suggested,
the introductory chapters have been extended and some sections rewritten entirely.
A point of discussion was whether new literature on in vitro propagation should
be incorporated. At the time of the first edition this field was relatively new for most
(mutation) breeders, but now we feel that the topic of in vitro techniques is ade-
quately covered in many easily accessible publications. As a consequence we have
decided not to try and cover the whole field.
We expect that, like its predecessor, this new edition will be a useful source of
reference for practical mutation breeding in vegetatively propagated crops for a
number of years. It seems likely that the number of new publications on mutation
breeding in the near future will be very limited. The mutation method seems well
established by now, and its possibilities as well as limitations are sufficiently known.
We further presume that within this field no major changes in approach will occur
in the immediate future.
In the years that immediately followed the appearance of the first edition of our
book, there was still a considerable increase in the literature on mutation breeding.
It appears to us that this situation is changing (with the possible exception of con-
tributions from Eastern Europe). This may be explained in various ways. First of
all, mutation work has become a matter of routine, for instance in breeding of or-
namentals, and is no longer mentioned explicitly as such. Secondly, much work that
was indicated in the past as mutation research, is called now "biotechnology" or
"genetic manipulation", even though the methods applied remain largely un-
changed. An example of this is the study of somaclonal variation and the irradiation
of in vitro plant material for induction of mutations. The present interest in
"biotechnology" and the observation that funds are withdrawn from mutation
work in favour of such methods, has led to a decline in the number of mutation
breeding research projects.
A positive development is the extension of the number of crops for which
breeders' rights can be obtained, as is the case with ornamentals in The Netherlands.

This situation stimulates practical breeding, including the application of mutation
breeding.
The literature in this book covers most of the important books and articles as well
as congress proceedings which have been published in languages accessible to us.
Most of them have been read by us, but some could not be obtained. Articles in
Chinese, Russian, Japanese and other unaccessible languages (to us and many of
our readers) in general are not included in the literature reviews. Most articles with
short English summaries only have also been excluded, because in the majority of
cases such articles do not contribute much to our knowledge of treatments and prac-
tical significance of the results obtained. Moreover, important data from such
research articles are generally also published in the proceedings of international
meetings and the like, in languages more accessible to us.
Another point concerns the nomenclature that is used by us for plants. Although
strictly speaking not quite correct, most plant species have been indicated by their
generic names only, as is the common practice in, for instance, the world of growers
of ornamental plants and in many publications concerning mutation breeding.
Finally, we hope that this edition appears at the right moment and will be as well
received as was the first.
