Quality Protein Maize “Qiandan 11 hao” is under the Guizhou bad disaster climate environmental condition, Breeds selectively corn new variety. ` After 1,997, 2,000, in 2001 3years experiment, observed the disaster climate to this variety influence. The result indicated that, This variety resistance is strong, The sowing time meets arid long clearly does not have the rain the weather, The soil field capacity is 43.5% (normal soil field capacity 60%), the rain water is insufficient, Rate of seedlings emergence above 85%, Basically achieves seedling is much longer and stronger; Jointing later period trumpet-shaped object stage, Meets the continuous and incessant rains little clear climate, Suffers the water logging disaster, Soil field capacity reaches above 85%,Partial is low-lying place is flooded, But the corn growth is normal, Ye Sachem is green, The root system is developed, Has not discovered the rotten root phenomenon; Is pulling out, the spinning, the pollination stage male, Bitter experience hot summer crop damage and storm disaster, The corn normally pulls out the male spinning pollination to busload, The output has notcreated affects greatly, Basically reaches higher authorities to year to year the stable production, Each 667m2 achieves above 560kg.
