“…Similar to our study, Nyadanu et al [15] reported leaf length and numbers of branches per plant and leaves per plant as traits that defined PC1 in their study. On the other hand, leaf width, days to first mature pods, and petiole length accounted for the variation observed in the accessions in PC2.…”

“…They also found that determinate growth habit, medium plant branching, and erect stems were the most important traits for production of leaves, which are edible part and are needed by farmers. Nyadanu et al [15] reported high variability in morphological traits in local cultivars of Ghana. The cultivars were grouped based on their geographical origin and traits such as number of leaves per plant, leaf length, and number of branches per plant were the most informative traits in differentiating the accessions.…”

Jute mallow is a traditional leaf vegetable that is an important part of daily diet for the majority of people in rural areas in sub-Saharan Africa. Here we employed quantitative and qualitative phenotypic traits to assess the morphological diversity of 90 accessions using univariate and multivariate analyses. Field experiments were conducted for two seasons to identify accessions suitable for leaf yield. The accessions were significantly variable in all traits. Highest variability among accessions was found in harvest index, biomass yield, and weight of 1000 seeds. The traits that significantly correlated with biomass yield include plant height ( = 0.448), petiole length ( = 0.237), primary branches ( = 0.319), and number of leaves per plant ( = 0.333). Principal component analysis showed that the first five PCs with eigenvalues ≥1 explained 72.9% of the total variability in the accessions. Pods per plant, primary branches, secondary branches, and number of leaves per plant accounted for highest variability in PC1. Cluster analysis grouped the accessions into five major clusters mainly based on their origin. Thus, the collection displayed high variation in morphological traits, particularly those related to leaf yield. These accessions are therefore useful in breeding for the improvement of the crop and germplasm management.

“…Corchorus is a genus belonging to Malvaceae family and is commonly known as, wild jute or wild okra (Jansen van Rensburg et al 2007). It is also widely known as jute mallow in other parts of Africa (Maina et al 2012;Ngomuo et al 2017;Nyadanu et al 2017). Africa has been reported as the center of diversity and source of origin due to high species diversity of Corchorus on the continent and for the reason that both wild and cultivated types, including Corchorus capsularis and Corchorus olitorius, are distributed throughout Africa (Edmonds 1990).…”

The genus Corchorus includes nutrient rich indigenous leafy vegetables often grown or harvested in the wild in Africa. It has potential to contribute to food security, but there is need to improve it as a crop through plant breeding. However, not much is known about the genetic variability among Corchorus species. The aim of this study was thus to characterise the available germplasm of Corchorus accessions and investigate heritability of their agro-morphological traits. Materials and methods: Eleven Corchorus accessions (4 South African and 7 from the World Vegetable Center) were evaluated in a field study at Roodeplaat, South Africa, for their morphoagronomic traits using a randomised complete block design with three replications across two seasons (2015/2016 and 2016/2017). Data were subjected to ANOVA, principal component analysis and cluster analysis. Broad sense heritability, genetic advance, genetic parameters and correlations were determined among the accessions and traits. 1 Results and conclusions: The Corchorus accessions showed significant (P<0.05) differences in all the quantitative traits evaluated. The data showed significant variability among the studied Corchorus accessions in their agro-morphological traits for exploitation in future breeding programs that in turn can contribute to the improvement of this crop.

Corchorus spp. is among traditional vegetable which is very nutritious and has been in use in many households in Africa. It contains high level of carotenoids (150µg/100g), vitamin C, Iron (190µg/g), 1.3% Calcium and 25.0% protein. The leaves are used in treatment of diseases and have wide antibacterial properties. It is semidomesticated and sometimes grows as a volunteer crop. Its status in some parts of Tanzania as a wild plant renders it unappealing for consideration in crop development programs.There is limited scientific information on its diversity for use as a vegetable in crop improvement and is a potential area for research. Variations exist among different accessions based on leaf shapes and color. Diversity studies by using molecular markers, proteins and isozymes are reported by several authors. There is low variation within species and high among species. Most of released varieties have a narrow genetic base. Conservation of this species in Africa is scarcely reported.
