Dry bean (Phaseolus vulgaris L.) is the most important legumes for human consumption worldwide and is an important source of protein, vitamins, and micronutrients in the human diet. This research aimed to i) uncover the genetic architecture of yield, Fe bioavailability and seed micronutrient concentration, ii) characterize the genetic control of canning quality traits, and ii) assess the accuracy of genomic prediction models for yield and end-use quality traits. The genetic architecture of yield and seed micronutrient concentration was assessed through a combination of meta-QTL analyses integrating published studies over the last two decades in dry bean. A Gaussian mixture model was used to determine the number of distinct QTL in the meta-QTL analyses. Consistent meta-QTL over different genetic backgrounds and environments were identified, reducing the confidence interval compared with initial QTL. Furthermore, a genome-wide association (GWA) study with 295 lines of the yellow bean collection and 82 yellow recombinant inbred lines identified a major QTL for Fe bioavailability related to the ground factor P gene. A black breeding panel with 415 lines was evaluated for yield and canning quality traits in two growing seasons. Consistent associations for color retention, appearance and texture of canned beans were identified across years. Genomic prediction models provided moderate to high accuracy for end-use quality traits on the yellow and black populations. The genomic prediction accuracy was related to the heritability of each trait, and improvement of accuracy was observed for complex traits when secondary traits were included in the model, while for traits with major QTL, the use of associated markers as fixed effects increased prediction ability. The use of meta-QTL analyses and GWA in this study lays a foundation of the genetic control of yield and end-use quality traits and reveals the potential of genomic prediction for these traits in dry beans.

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.

Common Bean (Phaseolus vulgaris L.) is cultivated all over Kosova in the home gardens and also in the fields. This country, with a very variable topography and climate is depending on a diversity of the landraces. This study showed varieties of common bean landraces which was gathered for a National Gene Bank. Five regions with 15 localities and five samples were collected at each locality. The varied altitude, climatic influences, and soils within Kosovo provide a wide diversity of micro-habitats to which plant and animal species are adapted. Genetic resources in general are spread throughout the word. It is always of interest to investigate in different countries. Kosova is a small geographical area in the heart of South East Europe with many characteristics, beginning in the cultural tradition, economical situation, historical past, and climatic condition, etc. Perhaps these characteristics can give rise to a specific trait that can be useful in future

This book provides insights into the genetics and the latest advances in genomics research on the common bean, offering a timely overview of topics that are pertinent for future developments in legume genomics. The common bean (Phaseolus vulgaris L.) is the most important grain legume crop for food consumption worldwide, as well as a model for legume research, and the availability of the genome sequence has completely changed the paradigm of the ongoing research on the species. Key topics covered include the numerous genetic and genomic resources, available tools, the identified genes and quantitative trait locus (QTL) identified, and there is a particular emphasis on domestication. It is a valuable resource for students and researchers interested in the genetics and genomics of the common bean and legumes in general.

During the past three decades there has been a large amount of research on biological nitrogen fixation, in part stimulated by increasing world prices of nitrogen-containing fertilizers and environmental concerns. In the last several years, research on plant--microbe interactions, and symbiotic and asymbiotic nitrogen fixation has become truly interdisciplinary in nature, stimulated to some degree by the use of modern genetic techniques. These methodologies have allowed us to make detailed analyses of plant and bacterial genes involved in symbiotic processes and to follow the growth and persistence of the root-nodule bacteria and free-living nitrogen-fixing bacteria in soils. Through the efforts of a large number of researchers we now have a better understanding of the ecology of rhizobia, environmental parameters affecting the infection and nodulation process, the nature of specificity, the biochemistry of host plants and microsymbionts, and chemical signalling between symbiotic partners. This volume gives a summary of current research efforts and knowledge in the field of biological nitrogen fixation. Since the research field is diverse in nature, this book presents a collection of papers in the major research area of physiology and metabolism, genetics, evolution, taxonomy, ecology, and international programs.
