Assessment of genetic variation of selected spiderplant (Cleome gynandra L.) morphotypes from western Kenya

Abstract

In the genetic variation study of the 4 spiderplant morphotypes, 10 out of the 12 primers screened generated 31 polymorphic bands. Nei’s coefficient of gene differentiation showed that the morphotypes were differentiated. Nei’s genetic identity value calculated from the RAPD data ranged from 0.3 to 0.6 indicating the degree of genetic identity between the morphotypes. Dendrograms constructed from a matrix calculated on the basis of UPGMA clustering algorithm revealed that the 4 morphotypes formed 3 groups.
