States. They cover such important topics as the in vitro selection of
resistant cells which can be regenerated into resistant plants, the us
of haploidy, embryo culture, and the production of hybrids by
protoplast fusion.
In view of the rapid progress of research in this field, and the important
practical implications of this research, there seems no doubt that
cell and tissue culture will play a major role in the future development
of crop production in the Asian Pacific region. We hope that this book
will make a useful contribution to the work of those who are already
engaged in cell and tissue culture, and will also be of value to those
who are now preparing to incorporate these techniques for the first
time into their national plant breeding programs.

Classification and Management of Rice Growing Soils

Rice is the staple crop in Asia, where soils have been cultivated for
rice for more than three thousand years. Since rice grows best in
standing water, wherever possible fields producing rice are leveled
and flooded. Pudding is also carried out, to reduce the permeability
of the soil.
This book contains a selection of papers from an international
workshop concerned with the classification and management of rice
growing soils, and with the off-season utilization of rice lands. The
transitionfrom the puddled and reduced state of the soil required by
rice to the well aerated and structured soil required by most upland
crops has created problems for both types of use. These problems
are related to soil management, soil fertility, pest and disease control,
and a range of scale-economic factors. Since the Workshop was
perhaps the first of its kind to address these problems, this book will
be useful to all those concerned with improving the productivity of
rice soils, with reference to both rice itself and off-season upland
crops.
