| Abstract: | replacement pigs and 64 fattening hogs were used as the trial materials for the experiment, on which comprehensive selection index was carried out. The results showed that the body height was positive, circumference of cannon and fat thickness were negative in the path analysis reseach. Its determinant coeffiencient was 60.7%, the qulification rate of selection 87.5%. |
