First, the purpose of the experiment Re-broadcast corn is a rapid development in Hetian area, cultivation of larger crops. To speed up the replacement of varieties, improve product yield, quality and grade, optimize the structure of varieties, especially arrangements for the test. Second, the test varieties In recent years, autonomous regions, scientific research, teaching departments to cultivate a new generation of hybrids 14, the control selection of the original varieties of eight farmers 701. Third, the test results analysis 1, the test varieties, there are 9 varieties of more than control. CX-431, yield 565.58 kg, 16.61% more yield than the control. Five varieties than the control production, of which 88-34 yield 380.57 kg, 21.5% reduction, ranking the last. 2, the varieties tested, the first 88-34 ripe, growth period of 83 days, 10 days earlier than the control; 608 the most late, the growth period of 101 days, 8 days late compared with the control, unripe harvest. 3, a comprehensive evaluation of selected. (1) CX-431: Height 2.84 m, 0.15 m above the control. Seedling dark green color, stem color purple. Flowering leaves green color, leaves half straight. pollen
