Study on the Correlation Between Microsatellite Markers and Body Weight in F2 Populations of Chicken

摘要

The genomes of 500 individuals in F2 population of Xianju chicken and Recessive White Chicken were screened using 26 microsatellite markers. The correlation between microsatellite markers and body weight were analyzed. The results showed that ADL 212 and LEI 147 on chromosome 2 were significantly associated with birth weight and weight at 12 week-age and the dominant genotype of these two loci were 118/103 and 295/262. MCW 4 and ADL 123 were significantly associated with birth weight and weight at 12 week-age, MCW 150 was related to 12 week-age weight. Meanwhile, MCW 223 and ADL166 on chromosome 5 were associated with birth weight, MCW 301, MCW 67 and ADL 210 on chromosome 8, 10 and 11 were associated with weight at 12 week-age.
