Abstract: To select suitable for Northern Xinjiang,under the condition of drip irrigation Tiannuo corn varieties and provides the theory basis for breeding new varieties. To the introduction of 34 Tiannuo corn ten major agronomic characters and the relationship between the fresh ear yield has carried on the descriptive analysis,correlation analysis and path analysis. The results showed that the volunteers' new varieties(combinations) of 10 agronomic traits variation coefficient distribution within the scope of 4.35%-70.44%,correlation analysis showed that ear length and fresh ear yield and leaf number and fresh ear yield was significantly correlated(r:0.423 1^**, r:0.339 3^*);Path analysis showed that the biggest characteristic of fresh ear yield function was ear length (P:0.599 3),the second ear rows(r:0.226 6,P:0.411 1),ear(r:0.118 1, P=0.240 7) and leaf number(r=0.339 3, P:0.240 6),respectively. Water-saving irrigation conditions,therefore,the main characters which influence the production of fresh ear was the spike length and spike number of lines,followed by ear and leaf number.

Key words: Tiannuo corn, Agronomic traits, Correlation analysis, Path analysis
