First, the source of variety: Comrade Do Bingyi made hybrid combinations in 1976, the combination is (North _ (15) × Nong 139) F_6 × (Gesh × North _ (11)) F_6. Second, the general characteristics: Middle-aged and semi-dwarf bars (about 90 cm), anti-down, disease resistance, cold, falling yellow good. Tillering strong, high rate of ear , As a multi-spike varieties. Third, the yield performance: According to Beijing Beijiao Farm Science and Technology Station uphill brigade in 90 acres of 90 acres of reproductive fields, plant height 74.4 cm, spike 441,000 / mu, spikelets 26.0, 1000 grain weight 35.6 grams, Economic coefficient of 44.8%, 608 kg per mu.Product than the experimental field,
