Plant Breeding

Plant breeding is the art and science of changing the genetics of plants for the benefit of humankind. A major goal of plant breeders is to select genotypes with stable and high performing phenotypes across environments. However, a selected genotype often performs differently across environments. This book presents a comprehensive review of various stability analysis methods and their application in plant breeding for selection of stable and high performing genotypes. Additionally, efficient methods to produce doubled haploid plants and to provide embryogenic suitable haploid cells systems are needed for future genetic manipulations and breeding in bread and durum wheat. This book describes a new stress in durum wheat, for its effectiveness to induce embryogenesis and regeneration plants. Along with its implications for plant selection, the methods used for dose-response variation are also explored, as well as the relationship between genetic variation and changes in dose-response behaviour. Other chapters in this book discuss the breeding strategy of self-incompatibility, an evolutionary force to preserve genetic variability in plants, the pros and cons of marker-assisted selection (MAS) breeding along with its future prospects, and the use of Joint Regression Analysis (JRA) in the management of plant breeding programs.
