Title: Analysis of disconnected diallel mating designs II: results from a third generation progeny test of the New Zealand radiata pine improvement programme.

Author: King, J.N.; Carson, M.J.; Johnson, G.R.;

Date: 1998

Source: Silvae Genetica. 47(2-3): 80-87

Publication Series: Scientific Journal (JRNL)

Description: Genetic parameters from a second generation (F2) disconnected diallel progeny test of the New Zealand radiata pine improvement programme are presented. Heritability estimates of growth and yield traits of 0.2 are similar to progeny test results of the previous generation (F1) generation tests. A trend of declining dominance genetic variance and increasing additive genetic variance with test age was noted. This trend probably represents artifacts affecting early growth of the full sib cross - such as seed size effects or other environmental biases rather than changing gene action.

Keywords: diallel analysis, radiata pine, hertability, GCA, SCA
