The objective was to combine a set of crossing and evaluation techniques into a regime that permits a breeder to conduct one cycle of recurrent selection for protein or grain yield of oats (Avena sativa L.) per year. Parental strains are crossed in the greenhouse during September to December, S₀ plants are propagated in the greenhouse during December to March, S_0.1 lines are evaluated in a replicated multilocation experiment in the field during April to July, and data summary and selection of parental lines for a new cycle occur during August. The schedule is repeated for each cycle. Over three cycles, the gain per cycle (and per year) was 4.7% for protein yield and 5.4% for grain yield. Techniques employed to permit completion of a cycle of recurrent selection in 1 year were: (i) approach method of crossing, (ii) evaluating S_0.1 lines, (iii) hill plots for field evaluation, (iv) infrared analyzer for N determinations, and (v) computer data analyses and line selection.
