Karyotype variations in Pisum sativum ect. abyssinicum

Abstract

P. sativum ect. abyssinicum was studied by karyotype and meiotic analyses. Two lines were investigated and resulted to be different from the standard P. sativum karyotype and from each other. Line 2 showed a reciprocal interchange involving chromosomes III and IV and both lines showed pericentric inversions in chromosome VI that involved different segments. © 1990 Taylor & Francis Group, LLC.
