In April 2016, a paper article has been published in Genome Journal by Dr. Nariman Salih Ahmad an academic staff at the Faculty of Agricultural Sciences, Field Crops Department. The Journal has an impact factor of 1.424 and it is been listed in Thomson Reuter Journal list.
The paper Article is titled: Construction of a genetic linkage map and QTL analysis in Bambara groundnut (Vigna subterranea (L) Verdc.).
The research is about the construction of genetic linkage map in bambara groundnut for the first time using different DNA marker. A total of 239 polymorphic DArT Array and SSR markers were utilised to construct the genetic map  using an F3 population from intra-specific cross. The map covered a total of 608.3cM of the plant genome. Some significant Quantitative Trait Loci (QTL) for important traits were identifying on the map positions which contribute actively to study the domestication syndrome and the development of this important crop. 



Bambara groundnut (Vigna subterranea (L.) Verdc.) is an indigenous underutilised legume which has the potential to improve food security in semi-arid Africa. So far, there are a lack of reports of controlled breeding populations that could be used for variety development and genetic studies. We reported here the construction of the first genetic linkage map of bambara groundnut using a F3 population derived from a ‘narrow’ cross between two domesticated landraces (Tiga Nicaru and DipC) with marked divergence in phenotypic traits. The map consists of 238 DArT array and SSR based markers in 21 Linkage Groups (LGs) with a total genetic distance of 608.3 cM. In addition, phenotypic traits were evaluated for a Quantitative Trait Loci (QTL) analysis over two generations. A total of 36 significant QTLs were detected for 19 traits. The phenotypic effect explained by a single QTL ranged from 11.6% to 49.9%. Two stable QTLs were mapped for internode length and growth habit. The identified QTLs could be significant for marker-assisted selection (MAS) in bambara groundnut breeding programmes.
