Correlation and path analysis of agronomic traits of introduced maize varieties
Maize is an important grain-fed crop,in order to promote farmers to increase production and income,this paper introduced 53 strains selected by Shandong Agricultural University in Fujian,analyzed the correlation of maize agronomic traits,and carried out partial correlation and path analysis.The results showed that kernels per row and the weight of 100 grains were significantly positively correlated with the yield,and the length of the bare tip was significantly negatively correlated with the yield;the path analysis showed that the positive relationship between row number per ear,the weight of 100 grains,kernels per row was the largest and the yield was the strongest,and the negative relationship between plant height,bare tip length and yield was the strongest.Therefore,in Fujian Province,row number per ear,the weight of 100 grains,kernels per row,and the length of bare tips affect the yield of maize,and maize varieties with good ear type,excellent ear traits and short bare tips should be selected in breeding.
