GREATER persistence of stands, particularly under grazing conditions, is a major objective of alfalfa breeding programs in the southeastern United States. Incorporation of the creeping-root character into adapted types of alfalfa offers one possible means of attaining increased persistence. If a plant breeding program is to advance most rapidly and efficiently, knowledge of the phenotypic and particularly of the genotypic interrelationships among and between morphological and physiological characters affecting plant growth and yield is necessary. The objectives of this study were to measure the phenotypic and genotypic relations of 11 characters in F2 populations from crosses between creeping-rooted and hay-type alfalfa clones, to obtain estimates of the magnitude of various types of genotypic variance in these populations, and to relate the information thus obtained to practical breeding procedure.
