Some workers have observed that triticale (X-Triticosecale Wittmack) is slower to dry down after maturity than is wheat (Triticum spp.). Laboratory water uptake rate studies were undertaken with threshed seed of triticale lines in an effort to identify lines with potentially differing drying rates. Drying rates of four lines and one cultivar of triticale were compared with those of two hexaploid wheat (T. aestivum L.) and one tetraploid wheat (T. turgidum var. durum L.) in windrowed and standing treatments in the field. The experiment was conducted in Saskatchewan, Canada on an Orthic Brown Chernozem; Aridic Boroll soil. Over 2 years, the triticales dried as quickly as, or in some cases, more quickly than the wheats. Similar results were obtained when the rates of kernel water loss after physiological maturity for standing wheat and triticale were compared over 4 years. The triticales tended to reach physiological maturity at higher kernel water concentrations than Glenlea wheat, which may have contributed to the faster drying rates of the triticales.
