Abstract:

It is studied on 29 millet varieties about the difference of nutrient quality characters, correlation, the principal component analysis and path analysis to enhance the target of quality breeding and efficiency. The results showed that, the nutrient quality characters were different, and the CV in the following order: crude protein > coarse fiber > fat > moisture > carbohydrate. Correlation analysis showed that, cured protein was highly significant negative with carbohydrate (correlation coefficient was -0.8224), highly negative with fat (correlation coefficient was -0.3807), and other nutrient quality characters were not evident. The results of principal component analysis and path analysis showed that, about 97.35% nutrient quality characters were decided by crude protein, fat, carbohydrate and coarse fiber, which could be used as indicator for selecting breeding materials, the determination coefficient was 1.0000. Fat and carbohydrate were typical characters of nutrient quality in breeding material selection, which should be selected in the low generation of breeding, moreover crude protein and coarse fiber should be selected in high generation.
