Genetic Characterization of Common Bean Accessions in Nigeria

This study apparently reveals the state of research in Common bean (phaseolus vulgaris L) in terms of crop improvement, been at its lowest level or non- existent in Nigeria. The study characterized some landraces of common bean (Phaseolus vulgaris L.) using mophor-agronomic traits by multivariate analysis during 2012 wet season to determine the extent of qualitative and quantitative Genetic variability. Accessions with appreciable performance were identified and suggested for further breeding programme. This compilation is written in simple language and easy to replicate methodology with pictures and figures for better grasp of the researched results. The study will be useful to plant breeders, plant scientist, geneticist and research a student carrying out diversity studies especially in lost and underutilized crop plants of leguminous species and others as well as a guide to identifying ecotypes/accessions/landraces with potentials for high yield as such enables generation of baseline data necessary for the development of a crop improvement programme.
