Karyotype studies on ten genotypes of onion grown in Jos Plateau, Nigeria

Abstract

The large number of inter-and intra-specific differences in the genus Allium has necessitated karyotype analysis of the cultivated species, in order to describe patterns and directions of chromosomal evolution, which affects morphological differences. In this study, ten genotypes of onion (Allium cepa L.

“…However, the Karyotype formulas reported here in this present study conflict with those observed in other literatures. The differences that exist in Karyotype formula and asymmetric indices suggest that structural chromosomal changes might have contributed to the morphogenetic slight differences in the genotypes [27].…”
