Triticale (X Triticosecale Wittmack) breeding programs in the Coastal Plain area of the southeastern United States have been conducted since the early 1970s. Most of the breeding work has concentrated on spring hexaploid grain types. Three spring type cultivars have been released: Beagle 82 (1982), Florida 201 (1986) and Sunland (1989). All three were selected from CIMMYT screening nurseries. Steady improvements have been made with grain yields, averaging 3918, 4160, and 4371 kg ha-1, for Beagle 82, Florida 201, and Sunland, respectively, over 17 trials during 1986/88 in Florida and Georgia. Test weights have shown a similar trend, averaging 62.8, 66.5, and 68.5 kg hl-1, for these cultivars, respectively, over the same 17 trials. An analysis of the protein content of seed from four trials with the three cultivars, showed an average of 12.3, 11.9 and 12.0 percent protein and 0.47, 0.43 and 0.47 percent lysine on a dry matter basis. Triticale has become quite popular as a feed grain among swine and poultry producers and is grown in double-cropping systems with soybeans or other summer annuals
