The level of natural outcrossing, after hand emasculation and open pollination, and the effectiveness of the Shell Chemical Co. Hybridization Agent (WL84811) to induce male sterility were studied in hexaploid triticale (Triticosecale× Wittmack). The results indicated a high level of outcrossing in triticale after hand emasculation and open pollination. Cross-pollination by wind readily occurred under Canterbury conditions giving up to 78% seed set, suggesting that hybrid seed could easily be produced in hexaploid triticale either by hand emasculation or by use of a chemical gametocide.
