Studies on Genetic Variability in Gerbera (Gerbera jamesonii Bolus Ex. Hooker F.)

Thirteen genotypes of gerbera were evaluated under naturally-ventilated polyhouse in Completely Randomized Block Design during the year 2011-12 to determine genetic variability, heritability and genetic advance for 15 quantitative traits, based on which selection may be made. Analysis of Variance sh...

High heritability (>60%) was observed for all traits except number of suckers/plant/year, flower diameter and flower-stalk diameter. High heritability, coupled with high genetic advance over per cent of mean, was observed for number of leaves/plant, leaf length, leaf width, days to bud-burst, days to first-flower opening, disc diameter, flower-stalk length, number of ray florets per flower head with length and width of ray florets.Rajiv KumarSociety for Promotion of Horticulture - Indian Institute of Horticultural Researcharticlegerberagenetic variabilityheritabilitygenetic advancePlant cultureSB1-1110ENJournal of Horticultural Sciences, Vol 8, Iss 1, Pp 111-113 (2013)
