Abstract: This study was conducted to determine meat quality between the hybrid F1 and F2 generations from Gallus gallus （♂） and Wen-chang chicken （♀）.60 1-day-old the hybrid F1 and F2 generations from Gallus gallus （♂）and Wen-chang chicken （♀） were randomly allotted to 2 groups with 3 replicates per group and 20 broilers per replicate，and were supplemented with the same diets. Ten hybrid F1 and F2 generations in each replicate were randomly selected to slaughter and sampled breast and leg meat to determine meat characteristics of meat on day 90 and 120.The results showed that meat traits of muscle between the hybrid F1 and F2 generations were significant differences at 90 and 120 days （P＜0.05），but there were no significant differences in pH and warner-bratzler shear force （WBS） of breast and pH of leg meat at 90 old days and 24 h drip loss and WBS of breast and leg meat and pH_{24 h} of leg meat at 120 old days （P＞0.05）. The diameter and density of muscle fibre were significant difference between the hybrid F1 and F2 generations （P＜0.05）, but there were no significant differences in that of leg meat at 120 old days （P>0.05），and hybrid F2 generation muscle fiber density was higher than that in hybrid F1 generation，especially the hen.There were no significant differences in the dry matter，crude protein and crude fat content and cholesterol level in muscle （P＞0.05）,however crude fat level of leg muscle was significant difference from hybrid F2 generation （P＜0.05）.In conclusion，meat quality of the hybrid F2 generation from Gallus gallus and Wen-chang chicken was excellent and utilizatied for meat，and slaughter at 120 days was more appropriate.
