VARIABILITY STUDIES ON YIELD AND YIELD ATTRIBUTING CHARACTERS IN FENNEL (FOENICULUM VULGARE MILL.) GENOTYPESRAVI KUMAR TELUGU, TEHLAN, S.K., MUKESH, K., KOWSALYA, N. AND MAMTHA N.C.
The experimental material consisted of fifty genotypes of fennel (Foeniculum vulgare Mill.) that were evaluated in a randomised block design with three replications at the Department of Vegetable Science, Chaudhary Charan Singh Haryana Agricultural University, Hisar (Haryana), during the Rabi seasons of 2015-16 and 2016-17. For all thirteen traits studied, the analysis of variance revealed substantial variations across genotypes. This demonstrated that fennel genotypes have a substantial level of variety. For majority of the traits studied, the overall mean and range values suggested plenty of variation. For characters like plant height, primary branches per plant, secondary branches per plant, days to 50% flowering, umbels per plant, umbellates per umbel, seeds per umbellate, seeds per umbel, seed yield per plant (g), seed yield per ha, harvest index (%) and test weight (g) the phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV) (Q). Plant height (cm), primary branches per plant, secondary branches per plant, umbels per plant, umbellates per umbel, seeds per umbellate, seeds per umbel, seed yield per plant (g), seed yield per ha (Q), harvest index (%), and test weight all had high heritability and moderate to high genetic advance as a percent of mean (g). This shows that among the genotypes studied, the attributing traits will be improved by selecting for yield and attributing traits.
