Triticale (X Triticosecale Wittmack) cultivars have been evaluated extensively in Oklahoma, Texas, and New Mexico. Grain yields of the more productive triticale have averaged 5 to 10% less than that of wheat [Triticum aestivum (L.) em Thell.], but some lines and cultivars have slightly exceeded the yield of wheat in recent years. Triticale yields, however, have been more variable than those of wheat. Test weight and overall grain quality in triticale are major faults, but some improvement in test weight has been observed in recent selections.
Forage yields of the most productive triticales have equaled the yields of the most productive wheats in the northern part of the region but have averaged less than rye (Secale cereale L.). Triticales grown in central and southern Texas have competed well with oats (Avena sativa L.) as a forage crop some years because of their greater resistance to foliar diseases usually prevalent in these areas.
It appears that cultivars of triticale presently available are not highly competitive with rye solely as a forage crop and not competitive with wheat, in the absence of sizeable and stable grain markets, as a dual purpose crop in the Southern Great Plains. Shorter height, earlier maturity, uniform ripening, and thresh-ability are needed improvements.
