Genetic Diversity, Population Structure and Biochemical Parameters Estimations Driving Variations in Groundnut Germplasm

What is it about?

Groundnut (Arachis hypogaea L.) is an exceedingly nutritious legume being employed for farming globally. The characterization of groundnut for genetic diversity and population structure can be used for unswerving detection of phenotype x genotype relations. Methods: The investigation was carried out with groundnut germplasm lines for nutritional and anti-nutritional profiling i.e., total sugars, proline, total amino acid, DPPH, phenol, phytic acid, flavonoid, lipid peroxidation and superoxide dismutase activity (SOD) along with molecular characterization and population structure analysis for early and late leaf spot diseases. Result: The heat map ranged between (-4 to 4) and represents the level of expression of diverse biochemical parameters. The genetic diversity for markers S008 and S053 ranged between 0.2293 to 0.5269 and PIC values ranged between 0.203 to 0.4224 for S008 and S053 molecular markers, respectively.

Why is it important?

Identified highly polymorphic SSR markers can be employedfor analysis of genetic diversity in other set of groundnutgermplasms. The study identified diverse clusters ofgermplasms with known check varieties and some uniqueclusters representing new traits in germplasm lines. Themorphological and molecular characterization of peanut(Arachis spp.) will be helpful in formation of strategies forcollection, conservation and development of new varietiesusing various germplasm lines. Also, identified groundnutgermplasm lines with superior characters could be used inhybridization programme for crop improvement.
