Abstract
[Objective] The aim was to calculate the grey relational degree between 1 000-kemel weight and main agricultural characters of maize, and sort them, to provide a theoretic basis for characters selection when maize breeding. [ Method ] Relation between 1 000-kemel weight and kernels per row, silking date, plant height, rows per ear, ear length, ear diameter, barren tip length, the number of the first branch of tassel, ratio of ear height etc were analyzed by grey relational analysis. [ Result] The results showed that the grey related degrees between barren tip length and 1 000-kemel weight was the biggest. The secondly was the number of the first branch of tassel. And then was ear diameter. The grey relational degrees between the ratio of ear height with 1 000-kemel weight was the smallest. [Conclusion] In maize breeding, the main goal is smaller barren tip and more the number of the first branch of tassel, at the same time coordinating all characters of ear and kernel, based on ensuring more rows per ear, longer ear and thicker ear diameter.关键词
