TL;DR: In this paper, the relationship between the cardiac glycoside contents in Corchorus olitorius seeds and the seed color was examined and a positive correlation (r = 0.913) was observed.
Abstract: The relationship between the cardiac glycoside contents in Corchorus olitorius seeds and the seed color was examined. The seed color was assigned a shade (color value) (L value in UCS system). The dark grayish green seeds, showing lower L value, contained more cardiac glycosides than dark grayish yellow seeds showing higher L value. When the total cardiac glycoside contents were plotted against the L values, a positive correlation (r = ‐0.913) was observed. Also, there was a higher content ratio of strophanthidin glycosides (erysimoside and olitoriside) in the seeds showing lower L value, while there was a lower content ratio of digitoxigenin glycosides (coroloside and glucoevatromonoside) in the seeds showing lower L value.

TL;DR: It was shown that the early segregation of the parental chloroplasts did not occur in jute, although this is common in other plant species, and the hybrid nature of the fused cell lines could also be identified through peroxidase isozyme analysis.
Abstract: A strong sexual incompatibility barrier that exists between the two cultivated jute species, Corchorus capsularis and Corchorus olitorius, limits the scope for improvement through genetic introgression. Protoplast fusion was carried out to generate interspecific hybrid cell lines. Cotyledonary cell protoplasts of C. capsularis and anthocyanin-pigmented hypocotyl protoplasts of C. olitorius were used in the fusion experiments, which appeared to be visually useful in the early selection of the fused products. A chloroplast DNA (cpDNA) marker was developed in jute, which showed species-specific hybridization patterns with EcoR1-digested total genomic DNA of C. capsularis and C. olitorius. This cpDNA marker was used in the characterization of the somatic hybrid cell lines at their early stages of growth. Evidence for the presence of both types of cpDNA in the hybrid cell lines was obtained when the total genomic DNA of 4- to 7-month-old hybrid cell lines was challenged with the chloroplast DNA marker through Southern analysis. It was shown that the early segregation of the parental chloroplasts did not occur in jute, although this is common in other plant species. The hybrid nature of the fused cell lines could also be identified through peroxidase isozyme analysis. Isozyme banding patterns were complex and varied among the hybrid cell lines.
