Abstract:
Thirty Hibiscus rosa-sinensis L. genotypes were evaluated for their morphological and yield attributes. Mean, Range, Co-efficient of variation (Phenotypic and Genotypic), heritability, correlation (Phenotypic and Genotypic), path analysis (Direct and indirect) were calculated for vegetative, flowering and yield parameters for all Hibiscus rosa-sinensis L. 30 accessions. Similarly, High heritability was observed for the characters, plant height (cm), number of primary and secondary branches/plant, leaf area (cm2), chlorophyll (SPAD value), days to bud initiation, days taken for flowering, flower longevity(Hrs.), pedicel length (cm), petal length (cm), petal width (cm), style length (cm) and shelf life (Hrs.). In the correlation, flower yield was positive and significantly correlated with plant height, number of primary branches, number of secondary branches, chlorophyll, petal length. Whereas, in path co-efficient analysis plant height, number of primary branches, petal length showed the positive direct effect on flower yield per plant per year.
