Abstract: Maize as an important food,feed and energy crops,widely grown around the world,the maize germplasm resources are scarce,the genetic base of maize is narrow,they are the main limiting factors of breeding research and production constraints raise.Therefore,understanding the main agronomic traits of germplasm resources for maize breeding is necessary to guide the maize breeding.This article mainly through the planting in the field and investigating the records,expound china synthesize kind 5 and 7 of the maize two species in Thing Hou Qi,plant height,stem thick,having been spread out leaf numbers and leaf number can .be seen,as well as the thrum color,the filament color, Male Guangzhou length,Guangzhou position height,Weight of a thousand seeds,Guangzhou number of lines,Guangzhou number of seeds and other agronomic characters.For maize Idioplasm Innovation and using provide theory and material base.
