Estimates of phenotypic diversity and genetic parameters of <i>Hibiscus cannabinus</i> L. grown in Burkina Faso

Abstract

Hibiscus cannabinus is a traditional leafy-vegetable consumed more and more in Burkina Faso. Its leaves and fruits are some good food supplement against nutritional deficiencies. Its fibers are also a source of income for households. Despite of its nutritional an economic potential, this species is underdeveloped in Burkina Faso. The study aims to determine genetic variability and level of heritability among agronomic interest traits of H. cannabinus using agro-morphological descriptors. This enable to identify outstanding accessions which could be involved in further breeding programs. A total of 70 accessions of H. cannabinus were characterized according randomized incomplete block, using 5 qualitative characters and 15 quantitative characters. The study showed great variability for most of the qualitative and quantitative characteristics studied. Several correlations were observed between characters related to the biomass, the fruits and the fibers production. These correlations are particularly interesting because the improvement of only one character induces improvement of the others. The study, moreover, shows high broad sense heritability (H 2) and weak differences between the phenotypic (PCV) and genotypic (GCV) coefficients of variation. These results indicate that the characters expression is under genetic control. So a direct selection method of H. cannabinus improvement is possible for these characters.

Ethnobotanical study of cultivated yellow nutsedge, (Cyperus esculentus L.) in Burkina Faso

“…They also have yellow tubers, the spherical of which are called female tubers or "mou tiama" and the non-spherical tubers called of male tuber or "mou balma". Similarly, according to Kabré et al (2019), farmers use colour to distinguish morphotypes of Hibiscus cannabinus L.…”

Drought tolerance in F1 interspecific hybrid between, Solanum melongena and its wild ancestor, Solanum insanum

“…The dispersion parameters of the phenotypic and genotypic data such as the phenotypic and genotypic coefficients of variation give indications on the level of variability of the phenotypic performances due to the differences between the phenotypes and the genotypes, but do not indicate the heritable and non-heritable part of this variability (Sawadogo et al, 2016;Gai and Lu, 2013). In fact, the higher the heritability (h 2 ) of the traits, the more effective the selection is and the association of the phenotypic (PCV) and genotypic (GCV) coefficients of variation with heritability provides better information on the prediction of phenotypic performance (Kabré et al, 2019;Afful et al, 2020). It's in this sense that this study analyses the morphogenetic characteristics of two accessions of the species S. melongena and S. insanum, their interspecific hybrid descendants (F1) for drought tolerance.…”
