“…During 2014-15 India exported raw jute of 88.6 M. tonnes worth 1006 crores, with the growing demand from the western countries for this biodegradable fibre, there is an urgent need to increase the yield levels. The yield levels of the cultivated varieties have plateaued as the most of the released varieties were developed from few selected parents (Kar et al, 2009;Benor et al, 2012;Kundu et al, 2013). The success of any breeding programme in developing high yielding varieties depends on the knowledge of nature and magnitude of genotypic and phenotypic variability present in the crop species (Abdurakhmonov and Abdukarimov, 2008).…”

An experiment was conducted to examine the magnitude of genetic diversity and characters contributing to genetic diversity among 81 tossa jute genotypes. Cluster analysis based on Euclidean squared distances and ward's method, the genotypes were grouped into ten distinct clusters. Analysis reveals that stick weight contributes maximum to the phenotypic diversity (65.52%) followed by green weight (13.64%) and fibre yield (10.10%). Among the clusters Cluster IX recorded highest mean fibre yield (19.91g) followed by Cluster VII (18.94g) and these clusters also recorded high mean values for plant height, basal diameter, green weight and stick weight. The highest intercluster distance was 186.80 (between clusters II and X) followed by 161.26 (between clusters IV and X), indicating the wide genetic diversity among these clusters. The highest intra-cluster distance was observed in cluster II (20.34) and the lowest in cluster X (3.17). The average inter-cluster distances were higher than the average intra-cluster distances, which shows the presence of wide genetic diversity among the genotypes of different clusters than those of the same cluster. The first two principal components, whose Eigen values are greater than one, accounted for 74% of the total variation among the five characters. The information obtained from diversity analysis is useful in planning further breeding programme for tossa jute improvement.

“…In addition, SSR markers have been widely used in genetic mapping and marker-assisted selection [15,16]. What makes SSRs such a powerful tool for genetic diversity studies is that SSRs have a high level of reproducibility, codominant nature CONTACT Siyuan Zhu zhusiyuan@caas.cn; Jianhua Chen cjhbt@sina.com and abundance [17][18][19][20][21][22][23]. Therefore, to date, SSR markers have been utilized to determine the genetic diversity in ramie.…”

Ramie (Boehmeria nivea L. Gaud) is one of the most important natural fibre crops. For enhanced crop development, it is necessary to understand its population structure and genetic relationships. In this study, we assessed the genetic diversity and population structure of 134 ramie accessions (with three plants per accession) from 12 regions by using 36 simple sequence repeat markers. The 36 microsatellite primers revealed 149 alleles in 134 ramie populations, with an average of 4.14 alleles per locus. The structure analysis divided the 134 ramie accessions into three groups (I, II and III), and into further six subgroups (a, b, c, d, e and f). In Subgroup b, 13 accessions were from Guizhou Province, 9 accessions were from Sichuan Province and the remaining 20 accessions were from Chongqing (4), Hunan (8), Guangxi (4), Jiangxi (2), Yunan (1) and Taiwan (1). In Subgroup d, 22 accessions were from Guizhou Province and the remaining 17 accessions were from Chongqing (6), Sichuan (5) and Yunnan (6). It can be inferred that the genetic background of these ramie accessions did not always correlate with their geographical regions. Similar results were found in Subgroups a and f. The pair-wise genetic similarity coefficients between the 134 accessions ranged from 0.390 to 0.939, which suggested that there was abundant genetic diversity in the ramie accessions. These markers have provided important information about the genetic structure of ramie, which can contribute to future breeding and improvement programmes for these resources.

“…has been investigated by several authors, white jute is said to be originated from Indo-Burma while the dark jute is said to be originated from Africa due to variation in morphological traits (Xiong 2008). Now it is well established that the two cultivated species (C. olitorius and C. capsularis) in Asia originated from Africa through the study conducted by using nuclear and chloroplast simple sequence repeats (SSRs) (Kundu et al 2013). This is also supported by a wide spread plant types present in the continent and occurrence of several related species (Kundu 1951;Benor et al 2012).…”

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.
