[0022] Firstly, the sterile plant of Triticale Lanyu No. 2 was selected as the female parent, and Agropyron mediterranea was used as the male parent for hybridization; then Agropyron mediterranei was planted in a greenhouse with a temperature of 23°C in August, and heated in winter to make the Keep at 15°C, use several 300-watt incandescent lamps to add light to the greenhouse, so that the light hours are 20 hours / day, so that the Mediterranean wheatgrass will bloom and loose powder in late April; The sterile plant Yu No. 2 was transplanted in a flower pot, and the glume of the sterile plant of Triticale Lan Yu No. 2 was cut off by one-third, so that the stigma was developed and exposed, and it was easy to receive external pollen; The sterile plants of Triticale Lanyu No. 2 were placed under Agropyrene mediterranea, so that the ears of Agropyron tritica were directly above the sterile plants of Agropyron triticale, and the pollen fell freely on the wheatgrass on the stigma of ...
