Abstract:
Twenty gaillardia germplasm have taken to measure association of yield components and their direct and indirect interaction with flower yield. Experiment was laid out in randomized block design with three replications and observations carried in monthly intervals. Correlation analysis showed the flower yield per plant was found to be significantly and positively correlated with stem girth, number of flowers, number of whorls, number of petals and single flower at both genotypic level and phenotypic levels. Number of branches, leaf area, first flowering, duration and flower diameter, observed positive and significant correlation at genotypic level only. Remaining traits results non-significant. Path analysis has revealed that flower yield per plant was directly and positively influenced by ten flower weight, flower diameter, days to commencement for flowering, number of whorls per flower, days to 50 per cent flowering, number of branches, stalk length and leaf area. The study showed that ten flower weights, flower diameter, days for commencement for flowering and number of whorls per flower are valuable characters in deciding the flower yield/plant. These characters may be considered as selection indices in gaillardia breeding programme.
