Correlation Analysis of Main Breeding Traits in Specific Line ZFD
摘要
Abstract
In order to choose the traits acting main function and even more efficaciously directing breeding, the canonical correlation among main traits of 247 specific line ZFD was conducted applying with Cancorr program of canonical correlation module of SPSS in this experiment. The results indicated that correlation among the traits of body weight, body measurement, age-corrected and backfat thickness-corrected of weighting at 100kg was significant. The first coefficients of canonical correlation of body weight with body measurement, body weight with age-corrected and backfat thickness-corrected of weighting at 100kg was significant(P＜0.01), the canonical correlation coefficients were 0.891 and 0.925, respectively, and represented 95.90% and 99.00% of total correlation. The first and second canonical correlation coefficients of body measurement with age-corrected and backfat thickness-corrected of weighting at 100kg were significant (P＜0.05), the first canonical correlation coefficients were 0.841, and represented 96.09% of total correlation. Results showed that weight, body length, chest girth for 6 month, age-corrected of weighting at 100kg were the main traits.关键词
