Abstract

Tree height is more responsive to family and within family selection than dbh. Kaldu P5 (30), Charet Mansu P4 (34) and Dohar PT1 (109) were found best performer. Site index curves were developed for Pinus roxburghii Sarg. (Chir pine) based on data from half sib progenies of Pinus roxburghii Sarg. established at UHF, Nauni, Solan (H.P.) Different models were employed to express height as a function of age. The model LnH = a+b/A 0.4 was found to be the best and was used to construct site index curves. Site index of 16.70 m, 15.90 m and 15.80 m at reference age 27 was obtained.
