Genetic Diversity of Jatropha curcas in Burkina Faso Revealed by Microsatellite Markers

Abstract

Jatropha curcas L. is a perennial oleaginous plant commonly used in tropical areas as a medicinal plant in the construction of defensive hedges against animals, and in the fight against water erosion. It produces oil which can be used as agrofuel or soap-making. Despite its potential, the species remain under-exploited and its genetic diversity is still not very well-known

Genetic variability and identification of potential drought-tolerant Burkina Faso sweet grain sorghum genotypes at the post-flowering stage using morphoagrophysiological traits

“…The marketing of panicles harvested at the pasty grain stage offers substantial income for farmers and sellers (Sawadogo et al, 2017). Also, its straw is an excellent feed for livestock (Tiendrebéogo et al, 2018). Despite the nutritional and socio-economic benefits of sweet grain sorghum, its production remains marginal in Burkina Faso compared to other food and cash crops.…”

“…It is very little exploited by the population, and its cultivation is still practiced on small plots surrounded by farmers' huts (Sawadogo et al, 2014a). The various research works previously carried out on this Sorghum mainly concern the endogenous knowledge associated with its management (Sawadogo et al, 2014a), its genetic diversity (Nebié et al, 2012;Sawadogo et al, 2014b;Sawadogo et al, 2018), the biochemical composition of grain (Sawadogo et al, 2017;Sawadogo et al, 2020) and straw , the effect of mineral fertilizers on its grain and fodder production (Tiendrebéogo et al, 2018;Tiendrebéogo et al, 2020), its genetic relationships with other cultivated Sorghum (Sawadogo et al, 2022a;Sawadogo et al, 2022b;Tiendrebéogo et al, 2022) and photoperiodism of genotypes (Tondé et al, 2023a). However, many challenges still remain to be addressed regarding this neglected crop, in particular, its response to the contrasting Sahelian climatic conditions where droughts occur more and more (Tondé et al, 2023b).…”

Variability and relationships between characters of physic nut (Jatropha curcas L.) in Burkina Faso

“…Indeed, J. curcas is still essentially a wild plant which must be the object of genetic improvement and domestication for its popularization and vaolrization [8,9]. In Burkina Faso, the genetic diversity of the species remains still poorly known [10][11][12][13]. Thus, within the framework of the promotion of the neglected or under-exploited local species, this study was initiated in order to contribute to a better knowledge the genetic diversity and the relationships between agro-morphological traits and seeds oil content of J. curcas.…”
