Genetic variability studies for fibre yield and its attributes in roselle (Hibiscus sabdariffa L.)

Abstract

Genetic variability analysis was studied in a set of 52 diverse genotypes of roselle (Hibiscus sabdariffa L.) during kharif, 2018 at Agricultural Research Station, Amadalavalasa, Srikakulam District, Andhra Pradesh for 11 quantitative traits. Analysis of variance indicated significant differences among 52 genotypes for all the characters under study. High PCV and GCV was recorded for green fresh weight per plant and dry fibre yield per plant. Moderate PCV and GCV was recorded for plant height and fibre wood ratio. Low PCV and GCV was recorded for days to 50% flowering. High Heritability coupled with high genetic advance as percent of mean was recorded for green fresh weight per plant, dry stick weight per plant and dry fibre yield per plant.
