Abstract: To assess the genetic variability present in seven genotypes (6 local collections and one check i.e (Double Mix) of gaillardia the experiment was conducted in a randomized block design with three replication in a plot size of 3.0 m x 3.6 m The plants were transplanted at spacing 60 x 45 cm. during the year 2015-16 in the Horticulture Section, College of Agriculture, Nagpur. Genetic variability and heritability studies indicated that there were highly significant differences between the genotypes for yield of flower ha-1 and fifteen other characters. Comparison of genotypic and phenotypic co-efficient of variation for different traits indicated that the values of PCV were higher as compared to GCV due to the influence of environment. The coefficient of variation both at genotypic and phenotypic levels were maximum for disc diameter, dry weight of flower, weight of flower, shelf life and leaf area. Therefore dry weight of flower, yield of flowers ha-1, diameter of flower, plant height and plant spread. Heritability estimates for all the characters except dry weight of flower were high. High heritability along with high genetic advance as per cent of mean was observed for dry weight of plant, yield of flowers ha-1, diameter of flower, plant height and plant spread which were due to additive gene effects thus suggesting that selection for these characters would be very effective. Based on these seven traits, genotypes NG 02, NG 01 and NG 03 were found significantly superior and identified for further purification and multiplication for their commercial exploitation
