TL;DR: Success is reported in producing a hybrid through the use of embryo culture technique in the hitherto unachieved reciprocal combination, namely, using C. olitorius as the pollen parent in the cross, C. capsularis × C. Olitorius.
Abstract: SINCE the first report1 of unidirectional success of the cross, Corchorus olitorius (♀) × C. capsularis (♂), Swamin-athan and Sulbha2 have also obtained hybrids in the same combination. Their reciprocal cross likewise did not yield any hybrid plants confirming the authors' earlier report. The fact that in this combination a small percentage of fruits was set with hormone application in 19583 encouraged me to repeat the cross at Cornell. The seeds resulting from the hybridization of these two species germinate with difficulty. It was, therefore, decided to develop suitable culture media for growing the hybrid seedlings in case hybrid seeds were obtained. This is to report success in producing a hybrid through the use of embryo culture technique in the hitherto unachieved reciprocal combination, namely, using C. olitorius as the pollen parent in the cross, C. capsularis × C. olitorius.

TL;DR: The acute toxicity of the alcoholic extracts of seeds, roots stems and leaves of the fully mature Corchorus olitorius L. plant was determined in mice by intraperitoneal injection and the cardiac glycosides content was estimated and the correlation between the two investigated parameters was established.
Abstract: The acute toxicity of the alcoholic extracts of seeds, roots stems and leaves of the fully matureCorchorus olitorius L. plant was determined in mice by intraperitoneal injection. The cardiac glycosides content of each extract was estimated and the correlation between the two investigated parameters was established. The chronic toxicity of the alcoholic extract of the seeds was determined in term of its haematological and symptomatical effects on mice upon intraperitoneal injection for a period of two months.

TL;DR: High population of plant- parasitic nematodes was recorded on the vegetable crops cultivated on covenant university farm and molecular characterization of the Meloidogyne species indicates Meloidogicalne incognita as the nematode species associated with the vegetables crops.
Abstract: Vegetable crops are highly susceptible to a wide range of pests and diseases among which are
the root-knot nematodes (Meloidogyne species). Traditionally, identification of Meloidogyne species
had been based on use of morphological characters such as the perennial pattern. In recent times,
accuracy of nematode identification using only morphological tools has been challenged due to
similarities in morphological characters of some nematode species. The aim of this study was to
identify the root-knot nematodes associated with some vegetable crops cultivated on Covenant
University farm, Ota, South-west, Nigeria using molecular tools and to determine the population
densities of Meloidogyne spp. on the selected vegetable crops. Plant-parasitic nematodes were
extracted from soil and roots of Abelmoschus esculentus, Celosia argentea and Core horus olitorius
cultivated on Covenant University farm. The nematode species were identified and counted under
a compound microscope. The molecular characterization of the Meloidogyne species was done using
single adult female nematodes and eggs which were picked out for DNA extraction and amplified
with specie-specific primers through Polymerase Chain Reaction (PCR) and separated on 0.5%
agarose gel. High population of plant- parasitic nematodes was recorded on the vegetable crops
cultivated on covenant university farm. Also significantly higher population (p<0.005) of
Meloidogyne spp. were found in association with C. argentea and Corchorus olitorius than those
recorded on Abelmoschus esculent us from the vegetable farm. The molecular characterization of
the Meloidogyne species from the farm indicates Meloidogyne incognita as the nematode species
associated with the vegetable crops.

TL;DR: Grouping of jute accessions based on morphological and molecular data was highly correlated and will be useful in future jute breeding programs.
Abstract: With an aim to develop mapping population on fibre fineness trait, grouping of 16 selected jute accessions, eight each from Corchorus olitorius and Corchorus capsularis which showed promising agronomic characteristics, was carried out using fibre fineness data and DNA fingerprinting using SSR and RAPID primers. Based on fibre fineness trait two subgroups depicting the fine and coarse fibre yielding accessions were obtained in each species. A total of 26 RAPID primers and 22 pairs of SSR primers yielded 277 and 41 scorable bands, respectively. High level of polymorphism was detected between fine and coarse fibre yielding jute accessions. Dendrogram showed that all the accessions formed two main clusters between C. olitorius and C. capsularis and each main cluster subdivided in two clusters containing fine and coarse fibre jute accessions. RAPID and SSR marker data-sets showed high levels of positive correlation (Mantel test, r = 0.97). Grouping of jute accessions based on morphological and molecular data was highly correlated. This study will be useful in future jute breeding programs.
