The inheritance of phenotype character of second generation (F2) on chicken (gallus gallus domesticus, linnaeus 1758) derived from crossing of pelung and broiler

The existence of germplasm of local chicken in Indonesia is quite numerous and very diverse. One of local chicken germplasm is pelung that has potency to be developed as a local type of broiler chicken. In this research performed crossing the first-generation chicken (F<inf>1</inf>) derived from crossing between Pelung and broiler. This research is to determine the phenotype characters inheritance of second generation (F<inf>2</inf>). The method used in this research was crossing chickens and observing in semi-intensive cage in Pusat Inovasi Agroteknologi (PIAT), Kalitirto, Berbah, Sleman, Yogyakarta. Measurement of second generation (F<inf>2</inf>) phenotype characters included quantitative data: weight of chicken, height of chicken, chest circumference, length of cockscomb, length of beak, length of wing, length of femur and length of tibia. While qualitative data that is in form of coat color, the color of feet and cockscomb shape. Weight measurements performed every week for seven week and observation of qualitative and quantitative parameters other than body weight after seventh week. The resulted showed that the second generations (F<inf>2</inf>) phenotype different from Pelung and broiler. The average second-generation chicken body weight in seventh week was 701,5 g (±83,44) which means it is heavier than Pelung, even though it has not exceeded the average weight of broilers. Second generation (F<inf>2</inf>) of chicken has a coat color: white, black, brown and black with white pattern (dotted), in addition chicken of second generation (F<inf>2</inf>) has a unique inheritance color of feet: there is black, white and yellow feet. © 2020 Elsevier B.V., All rights reserved.
