The Path Analysis Agronomic Character and Yield in Different Maize Varieties
摘要
Abstract
Thirty maize hybrids in different yield level as the materials in the study. The correlation and path relationship about yield and eleven agronomic characters were made by randomized block design. The correlation analysis indicated that yield and ear diameter, ear row number, seeding rate was significant positive relationship at 0.01 level, about plant height was significant positive relationship at 0. OS level, empty bar rate and lodging rate were significant negative relationship at 0. 01 level. The path analysis result indicated that the main agronomic characters and yield direct relationship was lodging rate > empty bar rate > seeding rate > plant height > ear height > ear diameter > 100-kernels weight > growth period > ear length, seeding rate, plant height, ear diameter, 100-kernels weight and growth period were positive intention, lodging rate, empty bar rate, ear row number, ear height and ear length were negative intention. It could that the increase lodging, seeding rate, 100-kernels weight and ear diameter .reduce empty bar rate and ear height in the maize varieties.关键词
