Genetic diversity within and among landraces of pearl millet (Pennisetum glaucum) under farmer management in West Africa

Abstract

The influence of farmer management on pearl millet landrace diversity was determined by evaluating variation in individual farmers' populations from two villages in north-eastern Nigeria. The variability within and between landrace samples was estimated using variation at 163 amplified fragment length polymorphism marker (AFLP) loci. The data indicated that individual farmers' husbandry practices result in the isolation of their own group of ideotypes each in their own unique genetic backgrounds, thereby rendering landrace names inappropriate as indicators of a generic genetic identity. The implications of these findings for sampling strategies for genebanks and regional genetic evaluations are discussed.
