Progress From Recurrent Selection Procedures For The Improvement Of Corn Populations, John H. Lonnquist
Progress From Recurrent Selection Procedures For The Improvement Of Corn Populations, John H. Lonnquist
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
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 …

Alfalfa Breeding, H. M. Tysdal, T. A. Kiesselbach, H. M. Westover
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Interest in the principles of alfalfa breeding has increased greatly with the growing "forage consciousness" of the country at large and the more specific interest developed through cooperation in the Alfalfa Improvement Conference. As is true of many other forage crops, information on the breeding behavior of alfalfa is meager. During the past few years, however, the genetics and principles of reproduction of this crop have come to be better understood and it is the purpose of this paper to bring together the available information pertaining to the improvement of alfalfa and to add certain suggestions with respect to future …

Corn Investigations, T. A. Kiesselbach
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The purpose of the investigations reported in this bulletin has been primarily to determine some of the underlying principles involved in corn improvement. The work comprises a study of some of the physiological characteristics of the crop together with a comparison of various selection, breeding, and cultural practices in their relation to grain yield.
