TLDR
In this paper, 138 jute genotypes of C. olitorius were characterized with ten jute specific SSR markers and 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.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.read more

Optimizing parental selection for genetic linkage maps
TL;DR: The objectives of this research were to calculate polymorphism information content values of 51 low-copy DNA clones and use the resulting values to choose potential mapping parents and to identify Genotype pairs that would map more highly informative DNA clones compared with a population derived from the most polymorphic potential parents.

Polymorphism revealed by simple sequence repeats
TL;DR: Simple sequence repeats are a group of repetitive DNA sequences that represent a significant portion of higher eukaryote genomes and can serve as highly informative genetic markers, and in conjunction with the use of polymerase chain reaction technology enable the detection of length variation.
