We report the first complete microsatellite genetic map of jute (Corchorus olitorius L.; 2n = 2 × = 14) using an F6 recombinant inbred population. Of the 403 microsatellite markers screened, 82 were mapped on the seven linkage groups (LGs) that covered a total genetic distance of 799.9 cM, with an average marker interval of 10.7 cM. LG5 had the longest and(More)
Jute is an important natural fibre crop, which is only second to cotton in its importance at the global level. It is mostly grown in Indian subcontinent and has been recently used for the development of genomics resources. We recently initiated a programme to develop simple sequence repeat markers and reported a set of 2469 SSR that were developed using(More)
Using a suite of morphological traits and neutral molecular markers, we have reevaluated the origins of the two cultivated jute species. The nine Corchorus species, which are restricted to both Africa and Asia, were phenotyped for bast fibre yield- and quality-linked traits, morpho-phenetically classified based on those traits’ similarities, genotyped by(More)
In jute (Corchorus olitorius), quantitative trait loci (QTL) analysis was conducted to study the genetics of eight fibre yield traits and two fibre quality traits. For this purpose, we used a mapping population consisting of 120 recombinant inbred lines (RILs) and also used a linkage map consisting of 36 SSR markers that was developed by us earlier (Das et(More)
We used RAD (restriction-site-associated DNA) sequencing to detect genome-wide SNPs and construct a dense linkage map using an intercross F2 population in jute (Corchorus olitorius). The linkage map comprising a total of 503 RAD markers in seven linkage groups spanned 358.5 cM with an average marker interval of 0.72 cM and covered 87.0 % of the genome.(More)
Bast fibre development in jute (Corchorus spp.) is a complex process that involves the differentiation of secondary phloic fibres (SPF) from the cambium followed by lignification of the fibre wall. We have identified a unique radiation-induced bast fibre-shy mutant of dark jute (C. olitorius L.), which is concurrently defective in the differentiation of SPF(More)
Here, we report the karyotypes and mean haploid idiograms of the ten Asian Corchorus species (2n = 2x = 14). Chromosomes were small, with a mean chromosome length of 2.30 μm. The largest chromosome was recorded in C. pseudo-olitorius (3.50 μm) and the shortest in C. pseudocapsularis (1.60 μm). The karyotypes of the two cultivated species (C. capsularis and(More)
Bayesian inference provides a principled way of estimating the parameters of a stochastic process that is observed discretely in time. The overdamped Brownian motion of a particle confined in an optical trap is generally modelled by the Ornstein-Uhlenbeck process and can be observed directly in experiment. Here we present Bayesian methods for inferring the(More)

Motion estimation is the most important component of any video coding standard. So development of an efficient algorithm for fast motion estimation is the basic need for video encoder design. Block based motion estimation algorithms are used for fast motion estimation as block matching algorithms eliminate the temporal redundancy present in any video(More)
