新疆 1984年引进南斯拉夫玉米SC704种子,经过在南北疆大面积生产示范,均获得高产,创造了新疆玉米大面积单产历史最高水平。SC704玉米是单交种,在生产上表现出许多优良特性。一、株型好,丰产性好,品质好。SC704玉米植株生长整齐,天花(雄花)、棒穗各着生在水平直线上。叶色深绿,宽厚,茎叶夹角小,株型紧凑,适宜密植,有利光合作用。天花分枝多,花粉量充足,棒穗结实饱满。果穗长,穗粗大、均匀,行粒多,粒重,出籽率高达85％以上籽粒半马齿型,品质较 Xinjiang introduced Yugoslavia corn SC704 seeds in 1984 and gained high output after large-scale production demonstration in both northern and southern Xinjiang, creating the highest historical record of large-area corn yield in Xinjiang. SC704 corn is a single cross, showing many excellent features in production. First, a good plant type, high yield, good quality. SC704 corn plants grow neatly, smallpox (male flowers), each with a rod spike in the horizontal line. Leaf color dark green, generous, small angle between stems and leaves, plant compact, suitable for close planting, favorable photosynthesis. More smallpox, enough pollen, full spike spike. Ear length, spike coarse, uniform, more grain, grain weight, seed yield as high as 85% of the grain half-dentate, the quality of more
