摘要
Xundan 20 was released by Hebi Academy of Agricultural Sciences in 2003. The stability, adaptation and yield components of Xundan 20 were analyzed using data from Huanghuaihai national tests in 2001 and 2002 and from high yield trials from 2005 to 2010. The results showed that variety Xundan 20 yielded most and increased significantly than Nongda 108 (Control, CK) in Huanghuaihai national tests in 2001 and 2002. The yield potential of variety Xundan 20 was so high that it created a series of new record in China. The yield of variety Xundan 20 of 15971.7 kg/ha created the highest record of summer maize in China in 2007, with the yield components of 77835 plant/ha, 205.2 g/ear, 596.16 grains/ear and 350 g per 1000-grain. The variation coefficient of variety Xundan 20 was small and its yield was stable. It is based on excellent comprehensive resistance of variety Xundan 20 to main disasters in Huanghuaihai region such as diseases, pests and lodging.
