Summary
An incomplete diallel cross with selfs and reciprocals was made with twelve cultivars of Gerbera jamesonii. Very significant differences occurred between GCA's of the parents for cut flower yield, earliness and number of lateral shoots. The selfs were mainly responsible for the significant SCA's.
A positive genetic correlation occurs between the number of lateral shoots at anthesis of the first flower and total flower production. The phenotypic performance of parents (measured on cuttings) was poorly related to their breeding value (measured on seedlings). It is suggested that this is due to physiological differences between cuttings and seedlings.
