Title: Correlation and Path Analysis of Main Ear Characters and Grain Yield of Maize
Abstract: Correlation and Path of major ear characters and grain yield of Maize were analyzed.The results indicated that correlation coefficient and path coefficient of ear length and other 7 ear characters in grain yield except length of the ear without kernels showed positive value.Among them,directly path coefficient of ear rows with grain yield was 1.300 42,directly path coefficient of kernels per row with grain yield was 0.903 82.So,when selecting high grain yield hybrids of maize,we must pay more attention to select gene types of more ear rows and more kernels per row.At the same time,The relationship of the ear length,kernels length,100 seeds weight and grain production rate,the relationship of the kernels per row,length of the ear without kernels and ear diameter etc,were important.
