Method for hybridizing wheat and mediterranean agropyron
A hybridization method, wheat technology, applied in horticultural methods, botanical equipment and methods, plant genetic improvement, etc., can solve the problems of poor hybridization, insufficient female stigma development, and less artificial pollination, so as to increase the chance of pollination , Break the incompatibility, improve the effect of seed setting rate

[0024] Firstly, the sterile plant of Wheat Lanyu No. 1 was selected as the female parent, and Wheatgrass 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 the greenhouse was kept at 15°C by heating in winter. ℃, use several 300-watt incandescent lamps to brighten the greenhouse so that the light hours are 15 hours / day, so that the Mediterranean wheatgrass will bloom and loose powder in late April; the wheat Lanyu No. The breeding plants were transplanted in flower pots, and the glumes of the sterile plants of Wheat Lanyu No. 1 were cut off by one-third, so that the stigmas were developed and exposed, and it was easy to receive external pollen; The sterile plants were placed under Agropyron mediterranea, so that the ears of Agropyron mediterranea were directly above the sterile plants of Wheatgrass No. 1, and the pollen fell freely on the stigma of the sterile plants of Wheatwort Lanyu...
