Fifty Fennel (Foeniculum vulgare Mill.) genotypes collected from different agro – climatic zones (Haryana, Rajasthan, Gujarat, Uttar Pradesh and Bihar) for their yield and yield attributing traits on pooled data (Rabi seasons of 2015-16 and 2016-17) recorded that there is a wide range of variability for the traits under study. The maximum plant height was recorded in HF-173 ( cm), whereas the minimum plant height was recorded in JF406 ( cm). The highest number of primary branches per plant and secondary branches per plant were recorded in HF-167 () and HF-168 () respectively. Early days to 50% flowering was recorded in HF-179 (). The maximum umbels per plant () and biological yield per plant ( g) was recorded in genotype HF-169. And the maximum umbellates per umbel () seeds per umbellate (), seeds per umbel (), seed yield per plant ( g), seed yield per ha ( Q), harvest index ( %) and test weight ( g) were recorded in genotype HF-171. | Mean performance of fifty genotypes of fennel (Foeniculum vulgare Mill.) for yield and yield attributing traits
