Variability in Some Roselle (hibiscus Sabdariffa L.) Genotypes for Yield and Its Attributes

Sixteen genotypes of Roselle (Hibiscus sabdariffa) were evaluated at Shambat (Sudan) for two consecutive seasons to assess genetic variability and heritability of different characters. Field experiment was conducted at Shambat Demonstration Farm in a randomized comp lete block design with three replications. Data were collected on thirteen plant attributes. Analysis of variance indicated significant differences among the sixteen genotypes for most of the characters studied. In general, the morphological characters had larger environ mental variances than their respective genotypic ones. The highest genotypic coefficient of variation was exh ibited by the seed yield/plant in both seasons. The highest genetic advance, 46.63 % in the first season and 170.13 % in the second season were obtained both for caly x yield/unit area. High values of heritability estimates (> 0.70) were recorded for days to 50 % flowering over the two seasons. On the other hand, the yield co mponents showed low heritability estimates (< 0.50) except for fru it weight in the second season.
