This study was conducted to compare productive performance between purebred Thai indigenous black-bone chickens and their reciprocal crossbreds. Four different genetic groups were studied: 2 purebreds (Chee Fah and Fah Luang) and 2 crossbreds (Chee Fah x Fah Luang and Fah Luang x Chee Fah). The results showed that Fah Luang x Chee Fah had the significantly highest body weight at birth and 20-week of age, while the lowest values were found in Chee Fah x Fah Luang (p<0.05). For feed conversion ratio, Fah Luang x Chee Fah had greater potential than purebreds and Chee Fah x Fah Luang (p<0.05). Additionally, Fah Luang x Chee Fah grew faster than the others (p<0.05). The productive performance of crossbred chickens was more favorable than purebreds. Considering crossbreds, Fah Luang x Chee Fah showed greater performance than Chee Fah x Fah Luang. Therefore, Fah Luang had more potential for using as a sire than Chee Fah.
