Synopsis Polycross, S 0 and S 1 progenies selected for superior vigor, leafiness, and resistance to foliage diseases were studied to determine the effectiveness of inbreeding as a breeding technique in a timothy improvement program. The results suggest that for strain improvement, extensive reselection of superior plants from large open‐pollination populations might be equally effective and more economical than would inbreeding and selection during initial stages of the breeding program.
