The combining ability studies made over environments (years) revealed that both g.c.a. and s.c.a. are influenced by environments. This suggested that to have unbiased estimates of g.c.a. and s.c.a. the studies must be made over a wide range of environments. As additive gene effects were predominant, the pedigree method of breeding would be desirable for obtaining pure lines with desirable characters. Simultaneously, the diallel selective mating system among the gocd general combiners, may be followed to release greater genetic variability.
