Studies on Genetic Variability, Heritability and Genetic Advance In Gaillardia (Gaillardia Pulchellafoug.)
Journal Title: IOSR Journal of Agriculture and Veterinary Science (IOSR-JAVS) - Year 2018, Vol 11, Issue 11
Abstract
The twelve genotypes of gaillardia (‘Genotype-1’, ‘Genotype-2’, ‘Genotype-3’, ‘Genotype-4’, ‘Genotype-5’, ‘Genotype-6’, ‘Genotype-7’, ‘Genotype-8’, ‘Genotype-9’, ‘Genotype-10’, ‘Genotype-11’ and ‘Genotype-12’) were evaluated to determine genetic variability, heritability, genetic gain for twenty five contributing characters. The results illustrated high value of phenotypic and genotypic co-efficient of variation for traits like number of ray florets per flowers (PCV = 47.41, GCV = 47.31) and weight of flowers per plant (PCV = 41.54, GCV = 41.47). High heritability with high value of genetic advance was observed for weight of flowers per plot, weight of flowers per plant, plant fresh weight, estimated flower yield per hectare, number of ray florets per flower, number of disc florets per flower and number of flowers per plant. High genetic advance as per cent of mean was observed for number of ray florets per flower, weight of flowers per plant, weight of flowers per plot and number of whorls per flower. It was observed that heritable variability in the breeding materials characters like number of ray florets per flower, weight of flowers per plant, weight of flowers per plot, number of disc florets per flower and number of flowers per plantcould be exploited for improvement through crop breeding programme.
