Collection and evaluation of Roselle (Hibiscus sabdariffa L.) germplasm in Nigeria

Abstract

In order to assess the genetic diversity of Roselle (Hibiscus sabdariffa L.) in Nigeria, a survey was undertaken to collect the germplasm of the crop. The survey cut across 56 towns and 20 villages in 17 states including the Federal Capital Territory (FCT). Sixty three (63) farmers were interviewed and 60 accessions of Roselle were collected from them. Results showed that 41.7% of these accessions were having green calyx, while 31.7% were with red calyx. On the other hand, 20.0% of the accessions possessed deep red calyx while only 6.7% have light red and pink calyx. Collections from the North Central, North Eastern, North Western and South Western parts were replicated over states, towns and villages. The highest number of Roselle accessions was collected from Kaduna State (8 accessions) followed by Niger State (6 accessions); Jigawa State (6 accessions) while FCT and Bauchi State have 4 accessions each. This is an indication that these areas have the greatest diversity of the crop genetic resources in Nigeria and the states might be secondary centre of origin of the crop. However, morphological as well as molecular characterizations are required to arrange the Roselle accessions collected into a suitable group; this will eventually provide the raw materials needed for the Roselle improvement programme in Nigeria.

Genetic diversity among four genotypes from Hibiscus rosasinensis in relation to drought stress

“…These results agreed with the data presented by both of Ahmed (2013) and also with Seeruttum and Sanmukiya (2013). The present study is in perfect agreement with the work of Omalsaad et al (2014), Daudu et al (2015) and Daudu et al (2016) on H. sabdariffa. It is also evident from the present results that RAPD molecular marker was able to detect small genetic differences among the different genotypes of Hibiscus rosasinensis.…”

Characterization, pollen behavior and propagation of five selected Hibiscus hybrids (Hibiscus rosa-sinensis Linn.)

“…A similar set of characteristics was developed for the Hibiscus hybrids falling under the series 'Women in Public Service' and 'Women in Science' and 'Women Saints and Institutions Named after Them' (Magdalita and Pimentel, 2013;Magdalita et al, 2016). In Nigeria, a similar phenotypic characterization strategy was conducted for the edible Hibiscus sabdariffa or roselle, where the different accessions were characterized for their calyx color to be either red, deep red, light red or pink (Daudu et al, 2015).…”

Comparative Analysis of Red Wine Produced from Hibiscus sabdariffa l. and Citrus sinensis Juice Using Saccharomyces cerevisiae Isolated from Palm Wine and Different Brands of Commercial Wine

“…commonly called 'sorrel' or 'red sorrel' is a plant that grows in tropical and subtropical climates while in Nigeria it is abundant in north-east and middle belt regions [20][21][22]. It is suggested to be a native of West Africa or Asia [23,24]. In some African countries, the calyx of H. sabdariffa which is usually of three types (green, red, and dark red) is used in preparing drinks.…”

“…Zobo is a refreshing non-alcoholic drink which is not usually produced in a commercial quantity because of its short shelf life not exceeding 24 h from the time of preparation unless it is refrigerated [21,27]. This notwithstanding, sorrel is increasingly becoming more attractive in the food processing industries due to its potential health benefits [23,28,29]. Wines are alcoholic beverages resulting from the fermentation of grape juices by yeast.…”
