Genotypic variation of groundnut bruchid Caryedon spp from different locations of Rayalaseema zone of Andhra Pradesh in India

Abstract

Study on genotypic diversity in groundnut bruchid Caryedon spp collected from various 24 different locations of Rayalaseema region of Andhra Pradesh in India. A molecular PCR-CTAB based test was used for molecular identification of Caryedon spp with using of the specific species primers of Caryedon serratus and Caryedon gonagra. Although genetic diversity was different between agro-ecological zones tests show no significant differences in structuring according to agro-ecological zone. These tests, as well as the phylogenetic relationships that our results imply, indicate that there is a genetic differentiation between individuals from groundnut storing areas compared to those from areas where the stored groundnuts is absent or low.
