A Comparison of Efficiency Parameters of SSR Primers and Genetic Diversity Analysis in Jute (Corchorus spp.)

Abstract: Jute (Corchorus spp.) is a natural bast fibre crop and has considerable commercial significance in the world after cotton, as it is a completely biodegradable, recyclable and environmental friendly lingo-cellulose fibre. For sustenance of the trade in the face of tough competition from synthetics, there is an urgent need to redesign the ongoing breeding strategy to improve both the yield and quality of jute fibre. It is therefore, essential to understand the pattern of genetic diversity in this important commercial crop species. Five Simple Sequence Repeats (SSRs) were amplified in 30 genotypes of both the cultivated species of jute Corchorus olitorius and Corchorus capsularis. The study was undertaken to identify the efficient SSR primers that could differentiate a set of 30 jute genotypes. Various efficiency parameters, namely: Polymorphic Information Content (PIC), Resolving Power (RP), Mean Resolving Power and Diversity Index (DI) were studied. The relationship between the parameters was studied using simple correlation coefficient. Dendrogram was constructed to find out the genetic diversity among the germplasm. These SSR markers will facilitate further studies in population genetics and utilization of this crop.

First report on the occurrence and symptomatology of phyllody disease in jute (Corchorus olitorius L.) and its plant characteristics in Turkey.

Abstract: Although jute (Corchorus olitorius L.) is treated as a weed in Turkey, it is cultivated and harvested for its fiber, tender shoots, and leaves in Africa and Asia. We report the occurrence and symptomatology of phyllody disease in jute observed for the first time in 2010 during our studies focusing on sesame phyllody in an experimental field at the Akdeniz University Campus, Antalya, Turkey. The disease was also observed in the following two years, 2011 and 2012. In the top of the infected jute plant, the internodes were shortened which resulted a cluster of leaves in smaller size than the normal ones, and the leaves were crinkled as well as turned to yellowing and leathery-looking. Additionally, the large leaves accumulated more anthocyanin in their margins. The floral organs abnormally developed into leafy structures; and ovaries at the symptomatic part enlarged but stamens and filaments did not show any symptoms. There was neither proliferation of the branches nor needle-like shape of the leaves in our case. Jute and sesame seeds started germination synchronously, and looked similar at the cotyledonary stage. Wild plants or weeds deserve a particular attention for disease development or inoculum build-up in cultivated crops. Considering the voluntary nature, jute may be an alternative for biofuel production. Also, the similarity in developmental stages of jute and sesame suggests that they might be affected by the same phytoplasma. To verify this, molecular analyses have been started

Corchorus olitorius. L extracting solution as well as preparation method and application thereof

Abstract: The invention provides a preparation method and an application of a corchorus olitorius L extracting solution Specifically, the preparation method comprises the following processes: adding corchorus olitorius L and water to a container, conducting heating and stirring, removing residues, conducting decolorizing by virtue of activated carbon and conducting concentrating, so that the corchorus olitorius L extracting solution is obtained The corchorus olitorius L is crushed corchorus olitorius L fine powder or fresh corchorus olitorius L leaves, and the grain size of the crushed corchorus olitorius L can be 200-800 meshes; the mass ratio of the corchorus olitorius L to the water is at 1 to (1-100); extracting temperature is 50-100 DEG C and an extracting duration lasts for 05-10h; the pH value of the corchorus olitorius L extracting solution is 5-7; the amount of the activated carbon added to the corchorus olitorius L extracting solution is 1-30% of the mass of the extracting solution; and by conducting decolorizing at 50-90 DEG C for 05-3h, the clear corchorus olitorius L extracting solution is obtained The corchorus olitorius L extracting solution provided by the invention has functions of whitening, moisturizing, repairing, moistening skin, resisting oxidation, resisting aging and the like; and the extracting solution is applicable to the fields of preparing cosmetic skin care products, foods, medicines and like

Genetic variability, heritability and genetic advance for yield related characters of tossa jute (Corchorus olitorius) genotypes

Abstract: The genetic parameters of variability were studied for seven yield related characters in forty-seven genotypes of tossa jute. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Highly significant genotypic differences were reported for all the characters. The maximum co-efficient of range were reported for green weight (g)/plant and stick weight (g)/plant followed by fibre weight (g)/plant, green bark thickness (mm) and core diameter (mm). The phenotypic and genotypic variances were the highest in green weight (g)/plant. The high PCV and GCV values recorded in stick weight (g)/plant. The maximum estimates of broadsense heritability were recorded in stick weight (g)/plant followed by fibre weight (g)/plant, green weight (g)/plant and plant height (m). The result from this study leads to the conclusion that green weight (g)/plant, fibre weight (g)/plant and stick weight (g)/plant should be considered during selections for yield in C. olitorius.

Spatial variation in Heavy Metal residue in Corchorus olitorious cultivated along a Major highway in Ikorodu- Lagos, Nigeria. 1 SANYAOLU, V.T., 2* SANYAOLU, A.A.A. AND 1 FADELE, E.

Abstract: This study focused on heavy metals (Lead (Pb), Zinc (Zn) and Cadmium (Cd)) contamination in the vegetable Corchorus olitorius (C.olitorius) leaves cultivated along a major road. Samples the vegetable, C. olitorius leaves) were collected from two sites, one of which is located on a major highway and the other remotely located from any form of industrial activity and which served as the control site. These samples were collected at distances of 10, 20 and 30m from the roadside and analyzed for Pb, Zn and Cd content by atomic absorption spectrophotometer. The mean concentration of heavy metals in the studied vegetable with effect to distance from the road was compared with the permissible values given by WHO/FAO. Mean concentration of heavy metal in C. olitorius leaves ranged from 0.013 to 0.310mg/kg, 2.500 to 4.850mg/kg and 0.063 to 0.205mg/kg at 10m, 20m and 30m distances respectively from the road. In all cases, it was observed that the closer the plants were to the road, the higher the heavy metal burden. The result of this study shows that, while the concentration of heavy metals in C. olitorius leaves from the control site remains constant, (i.e. showing no sign of contamination) the concentration of heavy metals in C. olitorius leaves cultivated along major road decreased with an increasing distance from the road. @JASEM
