Estimation of heritability and response to selection for cut-flower yield in gerbera

Heritability of cut-flower vase longevity in Gerbera

“…Estimates of broad-sense and narrow-sense heritability and a positive response to selection for cutflower yield has been reported for the Davis Population of Gerbera (HARDING et al, 1981). Estimates of general and specific combining ability for inflorescence characters have also been reported (MUCENIECE et al, 1978).…”

“…The details of the establishment, maintenance and mating scheme of the Davis Population are presented in HARDING et al (1981). Because the population was composed of half sib families, flowers (inflorescences) could be picked from a given plant, from its half-sib, and from unrelated plants.…”

Heritability of consumer preference in Gerbera

“…In this paper, as in HARDING et al (1981) H* will be used to distinguish broad-sense heritability from narrow-sense heritability (h2). A separate analysis was completed for the Y and P clones.…”

Heritability of inflorescence and floret traits in gerbera

“…These 80 genotypes and their respective parents were grown in a completely randomized design in the greenhouse. Details on the development, family structure, and culture of the Davis population are presented in DRENNAN et al (1983) andHARDING et al (1981).…”

“…Genetic variation and response to selection have been reported for cut-flower yield (HARDING et al, 1981) and consumer preference (DRENNAN et al, 1983) in a population of Gerbera hybrida grown in Davis, California. The population appears to possess moderate to high heritabilities for these traits and has responded to selection for cutflower yield and consumer preference.…”
