The morphological and genetical characteristics of the Nepalese native chicken were studied by somatometry and analysis of external genetic characters in the first investigation on Nepalese native domestic animals and their wild forms in 1986. Thirty five native chickens in Tarai area, made up of 7 males and 28 females, were measured for 7 different body parts and body weight. The principal component analysis using covariance matrix of 7 body measurements was applied to clarify the relationship between the Nepalese native chicken and other South-and Southeast-Asian chickens. Results of the principal component analysis are as follows : 1) The Nepalese native cock was placed between the Lanka native chicken and the non-game type Bangladesh chicken and close to the game-type Philippine and the Brown Leghorn cock, based on the discrimination afforded by the first component (size vector). For the second component (shape vector), the non-game type Bangladesh and the Lanka native chicken were placed in a similar position, and the Indonesian native chicken and the game-type Malaysian were placed together at the same position. The Nepalese cock took the intermediate position between these two groups. 2) Based on the first component, the Nepalese native hen was placed similarly to the cock between the Lanka native chicken and the non-game type Bangladesh chicken, this being the same position as the game-type Philippine and the Brown Leghorn, whereas the Lanka hen was in a position close to the non-game type Bangladesh , Phippine and Malaysian and the Australorp, and not far from the game-type Phlippine and the Lanka hen in the second component. 3) Both sexes of the Nepalese native chicken were close to the South-Asian native chicken population , viz. the Bangladesh and Lanka chicken, while there were no populations situated on the same position in the second component. Therefore , some differences were observed in body conformation between these South-Asian native chicken populations. The external genetic characteristics of 593 birds , viz. the feather and shank color, comb shape, ear-lobe color and other features, were recorded at 14 places in Nepal. The gene frequencies (q) controlling these morphological characters were calculated from the total number of birds. The frequencies of I, S and B genes were as low as those of other Asian countries. On the E allele, the Jpn. J. Zootech. Sci., 60 (1) : 88-96 88 1989 Somatometry and Phenotype of Nepalese Chicken frequency of the e+ gene showed a geographical variation ; i. e. the frequency was higher in the Solu-Khumbu area than in the other areas. Geographical variation was also recognized in the frequencies of the id gene. Concerning the comb shape, the Nepalese naitve chicken showed an extremely low value of P gene frequency. Jpn. J.
