1 section of the section of wheat identification Festival wheat seedlings dark green, base of purple, the new leaves when the roll volume for the cylinder, the leaves were bar-shaped; stalks of adult plants more delicate than the general wheat sheath tightly hold the leaf sheath, foliar Dense villi Festival of wheat tillering ability, vigorous growth, tillering leaf width less than 1/2 of wheat, the thickness of about 1/2 of wheat; heading higher than normal wheat, spike cylindrical, cob per node only Give birth to a spikelet.
