“…The hybrids may be also produced through interspecific crosses by using C. capsularis as female parent, which earlier authors reported to be unsuccessful. CONCLUSION This investigation revealed that successful interspecific crosses both at diploid and tetraploid levels among C. olitorius, C. capsularis and C. trilocularis were possible even without using hormone, irradiated pollen grains and grafting methods as followed The hybrids which we obtained showed luxuriance of growth in contrast to the weak, slow growing hybrids as reported by earlier authors (ISLAM and RASHID, 1960;SWAMINATHAN, et. aL, 1961).…”

“…Such distinction provides support to the earlier belief that the two species originated from two different geographical locations (Kundu 1951 This could be related to the strong sexual incompatibility barrier between these two cultivated jute species, which do not cross-fertilize (Patel andDatta 1960, Swaminathan et al 1961). But Islam and Rashid (1961), Choudhuri and Mia (1962) have succeeded in producing hybrids. However, all those putative hybrid showed dominance of the female parent in F 1 and F 2 generations with no varietal release.…”

The genetic diversity of 18 jute genotypes of the two cultivated species Corchorus capsularis L. and C. olitorius L. which include released varieties and collected races, referred to as accessions was evaluated. DNA profiling was generated using sequence independent RAPD markers. A total of 140 scorable loci were observed and a dendrogram was constructed with these markers. The relationship that is portrayed by this clustering also agreed with the available pedigree information on jute. Two major clusters representing the two species were resolved among the genotypes that were examined in the study. This genetic distance information could be useful in breeding programs in order to introduce agronomically important traits such as short field duration, low temperature tolerance, snow white fibre, higher harvest index etc. From the study one C. olitorius and two C. capsularis varieties were found more suitable for their selection as seed parent against different accessions for improvement because of their higher genetic distant relationship within species. However, more extensive molecular data are needed in order to reach a general conclusion about the relationship between jute genotypes.

An in vitro regeneration system for two varieties of white jute (Corchorus capsularis L.) namely, BJC-7370 and BJC-83 was developed. The regeneration protocol was based upon direct organogenesis from seedling-derived explants such as cotyledon with petioles, cotyledonary node. Shoot regeneration was achieved from cotyledon with petiole and cotyledonary node through use of MS supplemented with 0.5 mg/l BAP and 1.0 mg/l IAA for BJC-7370 while for BJC-83 shoot initiation was obtained on 1.25 mg/l BAP and 0.25 mg/l NAA using the same explants. Elongation of shoots was achieved on MS containing 0.2 mg/l BAP for the two said jute varieties. Regenerated excised shoots developed effective in vitro root system on half strength of MS supplemented with 0.3 mg/l IBA for both the varieties. The in vitro grown plantlets were transferred to soil for acclimation. These plants grew up to maturity, flowered and produced seeds identical to the control plants.
