Arachis pintoi accessions were morphologically characterized using a list of descriptors prepared by IBPGR/ICRISAT. Data from stems, leaves, flowers, pegs, pods, and seeds were collected. Phenotypic correlations were calculated among descriptors, and diversity indices were computed to access the genetic diversity among accessions. Principal component analysis was executed, and a cluster analysis was performed to group the germplasm. The germplasm presented great morphological variability with… CONTINUE READING
