Genetie and phenotypie paranıeters of Lalahan New Haınpshires in respeets of body weight egg weight egg produ eti on traits and estinıation of a seleetion index Suınnıary: The data analyserj, were furnished from 344 male and 33 i female individual progeny records involving 20 sires and 66 dams. Ht!ritabilities of 4, 6 and 8 weeks of age body weights were 0.39, 0.50, 0.5°from the sire components, 0.41, 0.55, 0.58 from dam components, 0.39, 0.52, 0.56 from sire dam . components respectively.

All positive correlations estimated between the egg weight and 4, 6, 8 weeks of age body weight traits while negative correlations estimated between the egg weight and egg production and also between the body weight and egg produc.ion ıraits. A selection index was constructedfor the egg weighı (xı), 8 weeks of age body weight (x ı ), egg production (x 3 ) as,.
