The genetic diversity of leaf vegetable jute mallow (Corchorus spp.): A review

Abstract

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.

Morpho-phenetical study of high yielding tossa jute variety BJRI Tossa Pat 7 (MG-1) for bast fibre yield and qualities

“…The LBR of jute leaf depends on the length and width of leaf lamina which indicates the leaf area. The more length and minimum width of jute leaf causes decrease in leaf angle and increase in LBR ( Ngomuo et al., 2017 ). The decrease in leaf angle increase the light incidence followed by increasing photosynthetic rate, growth, development and plant population per unit area of jute crop.…”

“…The jute leaf biomass depends on the weight of leaf lamina and petiole. The more leaf biomass or weight causes more dropping of leaves as well as more leaf angle resulting the shading effects on other leaves or plants, and limits the photosynthetic rate, plant population per unit area ( Ngomuo et al., 2017 ). The lowest leaf angle and leaf biomass; highest LBR and inter-nodal length of MG-1 results the maximum photosynthesis as well as fiber yield compared to O-795 and OM-1 varieties.…”

“…The jute variety having higher good quality fiber yield potentiality is the crying need of the farmers for the present situation contributing to the national economy. Generally the jute plant phenological structure having small leaf size, narrow lanceolate type leaves, lower number of leaves having lower leaf angle and correct petiole, smooth erect and cylindrical stem with maximum height showed maximum or optimum plant population per unit area ( Ngomuo et al., 2017 ). If the experimental plots will be over plant populated, the plants will be leaky thinner.…”

Effect of Textile Effluent on Dry Matter Yield and Nutrient Content Of Jute Leaves (Corchorus Capsularis)

“…Moreover, jute leaves can be used to fulfill the demand of leafy vegetables during the early summer in Bangladesh when leafy vegetables are scarce in market (Tareq et al 2019). The jute leaves are used in the treatments of many diseases and have wide antibacterial properties (Ngomuo et al 2017). Indigenous leafy vegetables are fairly easy to cultivate in terms of pest and disease control while producing very stable yields even under difficult climatic condition (Cunninghum et al1992).…”

Effect of textile effluent on the yield of jute leaves (Corchorus capsularis) in winter season

“…Leafy vegetables play an important role in human diets due to their ability to supply protein, energy, minerals, vitamins and certain hormone precursors (Antia et al 2006). The jute leaves are used in the treatments of many diseases and have wide antibacterial properties (Ngomuo et al 2017). Indigenous leafy vegetables are fairly easy to cultivate in terms of pest and disease control while producing very stable yields even under difficult climatic condition (Cunninghum et al 1992).…”
