Lonnquist, John H. (1961) Progress from recurrent selection procedures for the improvement of corn populations (Research Bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No. 197)
The possibilities of developing synthetic varieties suitable for the fringe areas of the corn belt, where cost of hybrid seed is high relative to the value of the expected crop, and in areas where hybrid corn might not be a feasible approach for other reasons, made it seem a worthwhile objective for study. Effort has been made in recent years to increase the productivity of hybrid combinations through selection of new superior lines using standard breeding procedures. The limited progress realized has resulted in an increased interest in the possible use of alternate methods for the development of superior germplasm pools which would provide worthwhile sources for new inbreeding and selection.
