The extent of variability, heritability and genetic advance for days to 50% flowering, plant Height (cm), no. of secondary branches / plant, no. of tertiary branches / plant, leaf length (cm), no. of nodes / plant, chlorophyll content (spad), herbage fresh weight (g), herbage dry weight (g). Whereas, characters, leaf width (cm), petiole length (cm), stem diameter (cm), internodes length (cm), pod length (cm), no. of seeds/pod, andrographiloide content were determine in 134 accession include 2 checks collected from different district of the Chhattisgarh along with 2 check in Anand Kalmegh (Directorate of Medicinal and Aromatic Plant Board) and Simmegha (Central Institute of medicinal and aromatic plants) in Andrographis paniculata. Analysis of variance revealed significant differences among the kalmegh genotype for different Character. Herbage dry weight exhibited maximum coefficient of variation at both level i.e. genotypic coefficient variation (GCV) and phenotypic coefficient variation (PCV). High heritability coupled with high genetic advance as percentage of mean was found in the character no. of tertiary branches/ plant, days to 50 % flowering, andrographiloide content followed by herbage dry weight/ plant and plant height.

Keywords: Andrographis paniculata, Andrographiloide, Heritability, Genetic Advance, Variability.
