Genetic Diversity in Corchorus olitorius Genotypes Using Jute SSRs

Abstract

Tossa jute (Corchorus olitorius L.) is an important lingo-cellulosic bast fibre-crop. It provides biodegradable and environment friendly fibre next to cotton, in terms of usage, global consumption, production, and availability. Narrow genetic diversity of the crop is the major hurdle, which is a demand at priority for any crop improvement programme. In the current investigation 138 jute genotypes of C. olitorius were characterized with ten jute specific SSR markers. A total of 23 alleles were amplified with an average of 2.3 alleles per locus and the PIC value ranged from 0.13 to 0.76 with an average of 0.455. The un-weighted pair-group method with arithmetic average cluster analysis of the 138 jute genotypes depicted a dendrogram using DARWIN, which divided the genetic resource into three major clusters. The study indicated the utility of SSR primers for providing useful and high levels of polymorphism for individual plant genotypes even with a narrow genetic base. Based on cluster analysis the most divergent genotypes identified were OIJ 167 (from Indonesia), OIM 058 and OIM 059 (India), however based on the agronomic traits as maximum plant height, basal diameter and fibre weight they were OIJ 245, OIJ (153 and 161) and OIJ 040, respectively.

RNA-Sequencing, Physiological and RNAi Analyses Provide Insights into the Response Mechanism of the ABC-Mediated Resistance to Verticillium dahliae Infection in Cotton

“…The overall loss that is caused by V. dahliae infection in cotton production is estimated to be 30%, being almost equal to losses as a result of various abiotic stress factors, such as drought, salinity, and or cold stresses [ 43 ]. Moreover, hybrid sterility and intensive selection has eroded the genetic diversity of the elite cotton cultivars, thus narrowing the genetic diversity of the current cultivated forms of cotton genotypes [ 62 ]. The application of the wild cotton species have helped to broaden the genetic diversity and the introgression of some of the novel genes into the cultivated cotton genome [ 43 ].…”

Variability and Character Association Study in Morphological Traits of Tossa Jute (Corchorus olitorius L.)

“…They also noted that the low variability for jute was recorded in case of plant height. Ghosh et al (2017) has classified 133 genotypes of jute in to 4 class, viz., below 1.00, class 1.01-2.00, class 2.01-3.00 and above 3.00. Among his studied genotypes plant height ranged from 2.11 [OIN 302 (India,Karnataka) Base diameter of the studied jute was ranged from 14.40 mm to 17.96 mm.…”

Morpho-anatomical variability, principal component analysis and Euclidean clustering of tossa jute (Corchorus olitorius L.)

“…It is a traditional cash crop in Bangladesh (Islam and Ali, 2017;Mukul et al, 2020a). It is a principal coarse fibre crop grown for commercial purposes in many south Asian countries (Alam and Rahman, 2000;Rahman et al, 2021), predominately in India and Bangladesh (Ghosh et al, 2015). Jute is a 'Golden Fibre' (Kundu, 1951;Ghosh et al, 2015) contributing about 4% GDP to the national economy and earns about 5% of the foreign exchange as well in Bangladesh (Islam and Ali, 2017).…”

During the period of 1980, 80% white jute, 10% tossa jute and 10% of both Hibiscus cannabinus (Kenaf) and H. sabdariffa (Mesta) were cultivated among the total cultivable jute crops in Bangladesh (Hossain, 2014).…”
