Abstract
Alectra vogelii threatens cowpea production in Sub-Saharan
Africa. The weed complicates the development and operation of
effective control tactics. For DNA extraction, young leaf samples
of A. vogelii were taken directly from infested cowpea fields. The
study used 23 SSR markers to determine genetic heterogeneity
among A. vogelii populations, which will help design and
implement effective breeding techniques and other parasite
control approaches. The effective number of alleles was 1.5648,
the observed number of alleles was 8, the anticipated
heterozygosity was 0.648, and Shannon's Information index
was 0.5169. PIC was 0.8301 on average. The Fst between
populations was 0.2986, leaving 70.14 percent genetic variation
within populations. A NTSYS -pc (UPGMA) dendrogram
developed three clusters. More information on genetic
heterogeneity among existing Alectra strains was gathered to
help expand the cowpea gene pool for selection and creation of
resistant genotypes.
