In this paper, canonical correlation of 8 variables in 2 group-traits (egg-laying and blood traits) for Jinyun ducks was analysed. The results showed that the first coefficient of canonical correlation between theegg-laying and the blood was 0.5650, reaching significance level and taking up 89.21% of the total correlations between 2 groups. Besides,the results also indicated that the highly significant correlations between 2 groups were caused by the highly significant correlations between the activity of Glutamat-Pyruvat-Transferase (GPT) at D60and 300d total number of eggs studied. The scope of the present study may provide some important references for early selection of Jinyun ducks by utilizing blood traits.
