Abstract:
The genetics control and phenotypic variability in morphological character of twenty accessions of lemongrass (Cymbopogon flexuosus) was studied at Raipur, Chhattisgarh for fourteen characters. High value of PCV than GCV indicate influence of environment. Minimum difference in PCV and GCV is found in number of tillers, plant height (cm), leaf length (cm), leaf area (cm²) show less influence of environment for the expression of such trait. High h² and GA % over mean was reported in plant height (cm), number of tillers, leaf length (cm), leaf width (cm), culm length (cm), culm diameter (cm), total chlorophyll (mg/g), spade value, fresh and dry herbage yield per plant (g) indicate additive gene action and selection of such character will be rewarded for yield improvement. These characters are stable and not influence by environment. The frequency curve also show normal distribution hence alleles controlling these characters in gene pool has normal uniform distribution.
