Variations of a 4‐factor factorial experiment were developed for estimation of components of variance due to general, 2‐, 3‐, and 4‐line combining ability effects in populations of 4‐clone alfalfa synthetics. Applications of the double cross and 4‐stage nested mating designs were also discussed. Knowledge of the relative importance of the components would be an aid in planning a breeding program.
