“…Therefore interspecific genetic variability needs to be exploited for developing genotypes with desirable attributes of both the species. Successful efforts to obtain interspecific hybrids between these two apparently cross-incompatible species have been made in the past, suggesting the feasibility of this approach (Islam and Rashid 1960;Swaminathan et al 1961;Islam 1964;Sinha et al 2004b).…”

“…At the interspecific level, however, the most diverse pair of genotypes involved genotype BZ-1-3 (CIJ-001) from Brazil (in sub-cluster Ia) belonging to C. capsularis and the genotype S-19 (JRO-620 9 Sudan Green) from India (in sub-cluster IIa), belonging to C. olitorius. Interspecific crosses between these two diverse genotypes may help combining desirable attributes from the two species, since interspecific hybridization has been successfully attempted and utilized in the past (Islam and Rashid 1960;Swaminathan et al 1961;Islam 1964;Sinha et al 2004b). …”

Jute is one of the most important fibre crops, which is second only to cotton in providing environment-friendly (biodegradable and renewable) ligno-cellulose fibre. In order to improve this largely neglected crop, we conducted a preliminary study involving the following: (i) analysis of nature and extent of the genetic variability for fibre yield and four other related traits in a set of 81 genotypes belonging to two commercially cultivated Corchorus species (45 genotypes of C. olitorius + 36 genotypes of C. capsularis), (ii) development and analysis of a set of simple sequence repeat (SSR) markers from C. olitorius, and (iii) use of a sub-set of SSRs for assessment of genetic diversity in the above set of 81 genotypes. The results suggested quantitative nature of fibre yield and other related traits, with a preponderance of dominance component in genetic variance. A sub-set of 45 SSRs derived from C. olitorius, when used for a study of DNA polymorphism and genetic diversity, showed high transferability of these C. olitorius SSRs to C. capsularis. The average number of alleles for individual SSRs was surprisingly low (3.04 for both species, 2.02 for C. capsularis and 2.51 for C. olitorius), and so was the average polymorphic information content (PIC; 0.23 and 0.24 in two species). In the dendrogram obtained using a similarity matrix, the 81 genotypes were grouped into three clusters, which largely corresponded to the two species, Cluster I belonging mainly to C. capsularis and the other two closely related clusters (clusters II and III) belonging to C. olitorius. It was also shown that a minimum of 15 SSRs could give the same information as 41 SSRs, thus making many SSRs redundant. The SSR markers developed during the present study and to be developed in future will prove useful not only for evaluation of genetic diversity, but also for molecular mapping/QTL analysis, and for comparative genome analysis of the two Corchorus species.

“…On the other hand, C. olitorius is relatively resistant to diseases and its fi ber is strong (Roy et al ., 2006). It would be very attractive to combine desirable characters of the two species in a single genotype and, understandably, attempts have been made for years to cross them but, so far, they have been unsuccessful (Chaudhuri and Mia, 1961;Datta et al ., 1960;Finlow, 1917Finlow, , 1921Finlow, , 1923Hoque et al ., 1988;Islam, 1964;Islam and Rashid, 1961;Patel and Datta, 1960;Sajib et al ., 2008).…”
