| Notes | 45-1381/S ZHANG Hua,WANG Xiu-quan, HE Dan, SHUI Hong-xia （1VIianyang Research Institute of Agricultural Sciences, Mianyang, Sichuan 621023, China） maize ; main agronomic traits ; yield ; stability ; correlation analysis [Objective ]The relationship between every agronomic trait and high-yield stability was studied to provide theoretical references for breeding superior maize varieties. [ Method ]Regression analysis model between agronomic traits of 52 maize varieties and average yield was built to calculate relevant correlation index, stability index and grey correlation degree using DPS software. [Result]Relationship sequence between six traits and average yield was ear length〉kernel number per row〉rows per ear〉plant height〉ear height〉bare tip length. Relationship sequence between six traits and stabili- ty was ear length〉plant height〉kernel number per row〉rows per ear〉ear height〉plant height〉bare tip length. From the cor- relation coefficient calculation results, ear length was mostly related to average yield |
