Abstract: Two local varieties of roselle (Hibiscus sabdariffa L.), Jamaican Green and Jamaican Red, were grown to determine the amount of natural cross-pollination. Two planting arrangements (alternating rows; alternating individuals in a row) and two planting dates, a month apart, were used for the outcrossing experiments. Stem pigmentation, red (R-) vs. green (rr), was used as a genetic marker in the estimation of outcrossing. Homozygous dominant and recessive genotypes of Jamaican Red and Jamaican Green, respectively… Show more

“…These findings are in consonance with observations of Vaidya (2000), who also found low crossability rates during a natural hybridisation studies in Hibiscus sabdariffa var Sabdariffa. These outcomes denote that only partial pair-wise design (Todd, 2013) may be possible for intra-varietal crosses involving accessions of Hibiscus sabdariffa var Sabdariffa.…”

“…Moreover, pollen viability and stigma receptivity are known to peak in the period immediately after opening of flowers (6 am-7 am) resultant of cleistogamous mode of pollination of roselle (Vaidya, 2000). Thus, crosses made in early hours of the day are more likely to be successful than those conducted later then.…”

“…Roselle (Hibiscus sabdariffa L.) is a self-pollinated (Vaidya, 2000) dicot plant (Malvaceae) cultivated across tropical and subtropical countries for myriads of uses (Akpan, 2000;Mostafa et al, 2005). Depending upon geographical region the species acquired various vernacular names viz., Roselle, Sorrel, Jamaica sorrel, Indian sorrel, Queensland Jelly plant, Jelly okra, Florida cranberry, Karkade, Bisap, Lal ambadi, Patwa (Morton, 1974;Gautam, 2004).…”
