Assessment of genetic variability in coriander (Coriandrum sativum L.)

An experiment was conducted at Main Experimental Station of Department of Vegetable Scienec, ANDUA&T, Kumarganj, and Ayodhya (U.P.) during Rabi season, 2020-21. Experimental material for study was consisted of sixty two coriander genotypes including two checks (Hisar Anand and ND Cor-2). The experiment was conducted in Augmented Block Design six blocks spaced 30 cm with plant to plant spacing of 15 cm. Each genotypes were grown in the plot size 2.0 m ×0.90 m. Observation were noted on eleven characters viz. days to 50% flowering (days), plant height (cm), nodes per plant, branches per plant, umbels per plant, umbellates per umbel, fruits per umbellate, fruits per umbel, umbel diameter (cm), 1000 seed weight (g) and seed yield per plant (g). The mean sum of square (analysis of variance) due blocks were highly significant for all eleven characters representing the variability among the genotypes considered in this study due to diverse genetic makeup of the genotypes. The higher extent phenotypic and genotypic coefficient of variation were observed for seed yield per plant. High heritability along with high expected genetic advance in per cent of mean was observed for most of the characters that provide good scope for further improvement in advance generations.
