TL;DR: These germplasm lines OIN-853, OIn-651, Oin-154, O in-125, OEX-27 and O in467, possessed good degree of resistance against stem rot of jute and were found moderately resistant under natural epiphytotic condition at Barrackpore and Bahraich location that would be further exploited for resistance breeding programme against this deadly disease.
Abstract: This study was aimed to identify more sources of resistance in jute germplasm (Corchorus olitorius) against deadly disease of stem rot. Thirteen C. olitorius jute germplasm including one standard check (JRO-524) were evaluated against stem rot disease at Barrackpore, Coochbehar and Bahraich location for two consecutive years 2012-2013. Out of thirteen germplasms of jute, six germplasms OIN-853, OIN-651, OIN-154, OIN-125, OEX-27 and OIN-467, with disease rating scale (1.1-5) were found moderately resistant against the stem rot disease at Barrackpore and Bahraich location. Whereas, OIN-270, OIN-932, OIN-270, OIJ-52, OIN-270, OEX-15 and OIN-853 with disease rating scale (5.1-10.0) were found moderately susceptible at all the three location. Rest of the lines were either susceptible or highly susceptible. These germplasm lines OIN-853, OIN-651, OIN-154, OIN-125, OEX-27 and OIN-467, possessed good degree of resistance against stem rot of jute and were found moderately resistant under natural epiphytotic condition at Barrackpore and Bahraich location that would be further exploited for resistance breeding programme against this deadly disease.

TL;DR: Evidence has been presented to show that earliness was associated with reduction in node number at first flowering and that four early mutants were superior to the control in yield of seed per plant, in addition to good quality fibre extracted from them.

TL;DR: The study based on a set of dark jute markers and morphological traits reveals that the extent of genetic diversity of cultivated jute mallow is moderate to high and could be used in germplasm evaluation.

TL;DR: Results shows that the phytochemical contents and antifungal activity of ethanolic leaf extracts of Corchorus olitorius and Gongronema latifolium in controlling the isolated fungi in vitro had a significant effect on the World Scientific News 53(3) (2016) 157-177 -158radial growth of the fungal pathogens at all the different concentrations tested as compared with the control.
Abstract: This study was carried out to investigate the fungal pathogens associated with post-harvest deterioration of maize seeds in storage in Oban community, Cross River State, Nigeria, determine the effect of the pathogens on the nutritional content of the maize seeds through biochemical analysis as well as evaluate the phytochemical contents and antifungal activity of ethanolic leaf extracts of Corchorus olitorius and Gongronema latifolium in controlling the isolated fungi in vitro. The fungal pathogens isolated as the causative agents of post-harvest deterioration of maize seeds in this study were Penicillium sp., Fusarium sp., Aspergillus sp., and Rhizopus stolonifer. The result of biochemical analysis of fungal infected and non-infected maize seeds carried out showed a significant increase (P ≤ 0.05) in the moisture content of the fungal infected maize seeds as compared to healthy ones (control), while there was a significant decrease (P ≤ 0.05) in the crude fibre, fat, ash, protein and carbohydrate contents of the fungal infected maize seeds as compared to the healthy ones (control). For the in vitro antifungal assay, various concentrations of the extracts ranging from 20g/200ml, 40g/200 ml, 60g/200 ml, 80g/200 ml and 100g/200 ml were separately added to PDA media. Results shows that at 60g/200 ml and 80g/200 ml and 100g/200 ml concentrations, ethanolic leaf extracts of C. olitorius completely inhibited the radial growth of Penicillium sp., Fusarium sp., Aspergillus sp., and R. stolonifer after seven days observation period while those of ethanolic extracts of G. latifolium completely inhibited the redial growth of the fungal pathogens at 40g/200 ml, 60g/200 ml, 80g/200 ml and 100g/200 ml concentrations. Results, however, shows that the extracts had a significant effect (P ≤ 0.05) on the World Scientific News 53(3) (2016) 157-177 -158radial growth of the fungal pathogens at all the different concentrations tested as compared with the control. Phytochemical screening of the extracts revealed the presence of cardiac glycosides, reducing sugars, flavonoids, saponnins, tannins, hydocyanin, and anthraquinones with traces of alkaloids.
