TL;DR: Although numerous attempts have been made during the last five decades, no hybrids combining the qualities of the two commercially most important species have been released so far, and these hybrids attained a greater height than the controls and were highly fertile.
Abstract: Although numerous attempts have been made during the last five decades, no hybrids combining the qualities of the two commercially most important species have been released so far. Dry seeds of Corchorus capsularis L. var. D-154 and Corchorus olitorius L. var. C.G. were irradiated with gamma rays of various intensities from 70 Kr. to 100 Kr. and were sown in the field. Abnormal plants of the first generation showing bilobed and crinkled characters in their leaves induced by gamma rays were chosen as male parents. 300 crosses of different combinations were made. In all 120 fruits developed into maturity. All the seeds failed to germinate except those from the crosses ♀ C.G. (0 Kr.) × ♂ D-154 (80 Kr.) and ♀ D-154 (0 Kr.) × ♂ C.G. (70 Kr.). F1 plants from the cross ♀ C.G. (0 Kr.) × ♂ D-154 (80 Kr.) inherited the bilobed character of the male parent whereas the plants from the other cross failed to show any sign of inheritance of the male parent. This indicated that the plants from the cross ♀ C.G. (0 Kr.) × ♂ D-154 (80 Kr.) were hybrids. These hybrids attained a greater height than the controls and were highly fertile.

TL;DR: Evidence is presented to indicate that high-fibre yield of an X-ray mutant, Tall Mutant, over the mother line R. olitorius and C. capsularis is mainly due to increased number of ultimate fibre cells.
Abstract: Repeated selection of tall and thick-stemmed plants made in a number of generations after treatment with X-rays and 32 P on jute seeds led to the isolation of 4 high-fibre-yielding mutants, 2 each in Corchorus olitorius and C. capsularis . The capsularis mutants had an unusual combination of characters of early-flowering and short-flowering period. Evidence is presented to indicate that high-fibre yield of an X-ray mutant, Tall Mutant , over the mother line R. 26 in C. olitorius is mainly due to increased number of ultimate fibre cells.
