Genetic variability assessment of accessions of Corchorus olitorius L. using sodium dodecyl sulphate polyacrylamide gel electrophoresis

Abstract: Corchorus olitorius is one of the neglected indigenous leafy vegetables in Nigeria. Majority of the accessions of this species stored at the National Centre for Genetic Resources and Biotechnology (NACGRAB) Moor Plantation, Ibadan, Nigeria, have only been characterized morphologically. To provide further information on the extent of genetic diversity, this study was initiated to assess the genetic variabilities among 14 accessions of the species using sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). Seven polypeptide bands were obtained ranging from 9.73 to 88.79 KDa thus depicting variations in the banding patterns of the accessions. The unweighted pair group method with arithmetic mean algorithm (UPGMA) dendrogram grouped the 14 accessions into two clusters and five groups with 50% of the accessions in one group. Accession 3 which was obtained from Lagos state was observed to be a very distant relative of the other accessions and so could be combined in a breeding programme with any of the others.

Genetic Divergence of Tossa Jute (Corchorus olitorius L.) for Fibre Yield and its Related Component Characters Under Moisture Stress Condition

Abstract: The present investigation studied genetic divergence of 60 genotypes of tossa jute (Corchorus olitorius L.) which included sixteen standard varieties to identify the most diverged genotypes under moisture stress condition. On the basis of mahalanobis D2 analysis, genotypes were grouped into five clusters. Maximum inter-cluster distance was observed between cluster IV and V while cluster III showed the maximum intra-cluster distance. Cluster V exhibited highest means for days to 50% flowering, plant height, number of node, internode length, base diameter, mid diameter, top diameter, bark thickness and fibre weight. The highest contribution (12.63%) was exerted by plant height of total divergence. The results of the present study suggested that hybridization between genotypes in cluster V and IV could provide a wide spectrum of variation in the segregating generation which could provide opportunity for isolation of drought tolerant with high fibre yielding lines.

Nutritional assessment of some indigenous leafy vegetables in northern Ghana.

Abstract: Greer, ieaty vegetables are herbaceous plants with different shapes which contain essential nutrients for growth and maintenance of the body. The study was conducted to identify the nutrient compositions of the some leafy vegetables; Ayoyo (Corchorus olitorius L. /, Bra (.Hibiscus sabdariffa L. var. sabdariffa), Cassava (Manihot esculenta Crantz) leaves, Cowpea (Ugna unguiculaiaj leaves, Bitter leaf (Vernonia amygdalina Del) and Pumpkin (Cucurbita maxima Duch. ex Lam. leaves which are among the indigenous green leafy vegetables commonly grown and consumed in the three northern regions of Ghana. Samples were taken at two andfour weeks after germination. The results ofthe samples showed appreciable levels of moisture, orotein, fat,fibre and ash. There were however, nutrient variations at the different stages at which samples were taken.

Molecular Characterization of Corchorus olitorius L. of Burkina Faso

Abstract: Corchorus olitorius is more and more cultivated in Burkina Faso because of its socio - economic interest. Hence the objective of this study which will contribute to improve the knowledge of the genetic diversity of the species in Burkina Faso. To this end, seventeen SSR markers were used to characterize ninety-six (96) accessions of the four phytogeographic sectors of Burkina Faso. These accessions consist of 16 accessions of the variety C. olitorius var insicifolius and 80 accessions of the variety C. olitorius var olitorius. The results of the analysis of the diversity of microsatellite markers tested, they were seized sixteen (16) of the seventeen (17) SSRs are polymorphic with a rate of polymorphism of 92.19 % and number of 53 alleles with a mean of three (3) alleles per locus. As for the Shannon diversity index, with an average of 1.05, it is between 0.53 for the HK-27 marker and 1.90 for the HK-19 marker. The polymorphism information content (PIC) potential ranged from 0.11 for the HK-12 marker to 0.49 for the HK-6 marker with an average of 0.32. A structure of diversity into three groups regardless of phytogeographic areas or botanical variety has always been.

Studies on Divergence for Fibre Yield and its Contributing Traits in Tossa Jute (Corchorus olitorius L.)

Abstract: Jute Christened as The golden fibre is the second most important textile fibre next to cotton. A field experiment with thirty diverse genotypes of jute (Corchorous olitorius L.) was undertaken at the teaching farm of Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal. For evaluation of yield characters based on D2 analysis, 30 genotypes were grouped into eight clusters. Cluster I had highest number of genotypes (18) followed by cluster II while cluster III, cluster IV, cluster V and cluster VI accommodated 2 genotypes each whereas cluster VII and VIII included solitary genotype. Maximum inter cluster distance was observed between cluster VII and cluster VIII and closely followed by VI and VII, while the minimum inter cluster distance were observed between cluster II and cluster III. Dry fibre weight per plant−1 followed by dry stick weight per plant−1 was the maximum contributors to total genetic divergence.
