APPENDIX............................................. 353 ACKNOWLEDGMENTS The investigations on which the present monograph is based, because of their wide scope and nature, could not have been carried on without the active participation of many individuals. Whatever merits it may have are due in great part to their enthusiasm and coordinated efforts. The authors alone, how- ever, wish to assume responsibility for any shortcomings. We are much indebted to our colleagues, the staff members of the Cooperative Program for Maize Research and of the Universidad Agraria, La Molina,
