Abstract: The polymorphism of Lipopretein lipase （LPL） gene was detected in black Muscovy duck by PCR\|SSCP， and the correlation between LPL gene polymorphism， routine meat quality， and muscle nutrients were analyzed. It was shown that the mutation of A\|G was discovered at the 4th site in intron 3. The homozygosity was 05054 in the whole population. The polymorphic information content was 03723. The mutations formed EE， EF and FF genotypes. The water loss rate of EF female duck was significantly （P<005） higher than that of FF female duck. The Mg content in leg muscle of the EF male duck was significantly （P<005） higher than that in the FF male duck. The Ala content in chest muscle of the EE male duck was significantly （P<005） higher than those of the EF and FF male duck. The Asp and His content in chest muscles of the FF female duck were significantly （P<005） higher than that of EF female duck. The contents of Ser and Pro in leg muscles of the FF male duck were significantly （P<005） higher than those of EE male duck. The Lys content in leg muscles of the EE female duck was significantly （P<005） higher than that of EF female duck，and the Cys and Val contents of EF female duck were significantly （P<005） higher than those of FF female duck.
