Book Description
One of the objectives of the HortResearch apple breeders is to develop new high quality apple cultivars with red flesh Previous studies identified a candidate gene controlling red colour in apple, MdMYB10, and led to the development of a molecular marker, Nzsnp_MdMYB10, within this gene. This present study maps the location of the red flesh gene on the apple genome, using a set of published microsatellites and Nzsnp_MdMYB10. We show the red flesh gene MdMYB10 is located on linkage group 9.Another objective of HortResearch is to develop disease resistant cultivars to decrease the use of pesticide. Apple scab is the major apple disease worldwide and is caused by the fungus Venturia inaequalis (Cooke) G,Winter. Several resistance genes are already known and used ; but some of them, for example Vf, have been circumvented by new V,inaequalis races. There is a need for durable scab resistance with new genes and the accession 'Dolgo' represented a new unused source of resistance to apple scab. This study maps the location of the gene Vdolgo on the apple genome using a whole genome scan approach. We show Vdolgo is located on the linkage group 2 in a region rich in apple scab resistance genes (i.e. Vr, Vbj, Vh2, Vh4, Vh8).

Book Description
This book covers information on the economics; botany, taxonomy, and origin; germplasm resources; cytogenetics and nuclear DNA; genetic improvement efforts of scion cultivars; genetic and genomic improvement efforts of rootstocks; genetic and physical mapping; genomic resources; genome and epigenome; regulatory sequences; utility of whole-genome sequencing and gene editing in trait dissection; flowering and juvenility; cold hardiness and dormancy; fruit color development; fruit acidity and sugar content; metabolomics; biology and genomics of the microbiome; apple domestication; as well as other ‘omics’ opportunities and challenges for genetic improvement of the apple. The cultivated apple (Malus x domestica Borkh.) is one of the most important tree fruit crops of temperate regions of the world. It is widely cultivated and grown in North America, Europe, and Asia. The apple fruit is a highly desirable fruit due to its flavor, sugar and acid content, metabolites, aroma, as well as its overall texture and palatability. Furthermore, it is a rich source of important nutrients, including antioxidants, vitamins, and dietary fiber.

Book Description
Wild crop relatives are now playing a significant part in the elucidation and improvement of the genomes of their cultivated counterparts. This work includes comprehensive examinations of the status, origin, distribution, morphology, cytology, genetic diversity and available genetic and genomic resources of numerous wild crop relatives, as well as of their evolution and phylogenetic relationship. Further topics include their role as model plants, genetic erosion and conservation efforts, and their domestication for the purposes of bioenergy, phytomedicines, nutraceuticals and phytoremediation. Wild Crop Relatives: Genomic and Breeding Resources comprises 10 volumes on Cereals, Millets and Grasses, Oilseeds, Legume Crops and Forages, Vegetables, Temperate Fruits, Tropical and Subtropical Fruits, Industrial Crops, Plantation and Ornamental Crops, and Forest Trees. It contains 125 chapters written by nearly 400 well-known authors from about 40 countries.

Book Description
The global demand for high quality fruits that are rich in nutrients and that can endure the demands of worldwide supply chains is growing rapidly. Fruits are an important component of the human diet, providing vitamins, minerals, antioxidants, and fiber. All of these qualities contribute to the nutritional needs and health maintenance of humans. Breeding for Fruit Quality reviews the application of modern plant breeding methods to the development of improved varieties of fruits. Breeding for Fruit Quality opens with chapters that look at fruit biology and breeding strategies behind specific traits, including a look at traits such as organoleptic quality, nutritional value, and improved yield, among others. Subsequent chapters review breeding efforts to improve overall quality in a wide range of specific fruits. Providing broad ranging coverage of cutting edge methods now being applied to the development of fruit crops, Breeding for Fruit Quality will be a valuable resource for fruit biologists, breeders, geneticists, and industry personnel. Key Features: Broad coverage of modern breeding technologies being implemented to improve overall fruit quality Trait specific chapters explore efforts to promote traits of industrial and nutritional importance Chapters in fruits, ranging from apple and grapes to tomatoes and olives, provide detailed coverage of breeding practices for economically important fruit crops

Book Description
Amongst the many problems facing the apple industry, apple scab is one of the most challenging experienced by producers. This disease is caused by Venturia inaequalis, which causes lesions to develop on both the fruit and leaves. The fungus is usually controlled by extensive use of sprays, but molecular genetics have made more environmentally friendly techniques available. This study was aimed at constructing a genetic linkage map from apple, which would be used in marker-assisted selection (MAS).

Book Description
This book covers the biotechnology of all the major fruit and nut species. Since the very successful first edition of this book in 2004, there has been rapid progress for many fruit and nut species in cell culture, genomics and genetic transformation, especially for citrus and papaya. This book covers both these cutting-edge technologies and regeneration pathways, protoplast culture, in vitro mutagenesis, ploidy manipulation techniques that have been applied to a wider range of species. Three crop species, Diospyros kaki (persimmon), Punica granatum (pomegranate) and Eriobotrya japonica (loquat) are included for the first time. The chapters are organized by plant family to make it easier to make comparisons and exploitation of work with related species. Each chapter discusses the plant family and the related wild species for 38 crop species, and has colour illustrations. It is essential for scientists and post graduate students who are engaged in the improvement of fruit, nut and plantation crops.

Book Description
Fruit Breeding is the eighth volume in the Handbook of Plant Breeding series. Like the other volumes in the series, this volume presents information on the latest scientific information in applied plant breeding using the current advances in the field, from an efficient use of genetic resources to the impact of biotechnology in plant breeding. The majority of the volume showcases individual crops, complemented by sections dealing with important aspects of fruit breeding as trends, marketing and protection of new varieties, health benefits of fruits and new crops in the horizon. The book also features contributions from outstanding scientists for each crop species.

Book Description
This book deliberates on the concept, strategies, tools, and techniques of allele mining in fruit crops and its application potential in genome elucidation and improvement including studying allele evolution, discovery of superior alleles, discerning new haplotypes, assessment of intra- and interspecific similarity, and also studies of gene expression and gene prediction. Available gene pools in global germplasm collections specifically consisting of wild allied species and local landraces for almost all major crops have facilitated allele mining. Advanced genomic techniques have been developed including PCR-based allele priming and Eco-TILLING-based allele mining that are being widely used now for mining superior alleles. Allele discovery has become more relevant now for employing molecular breeding to develop designed crop varieties matching with consumer needs and also with genome plasticity to adapt the climate change scenarios. All these concepts and strategies along with precise success stories are presented over the chapters dedicated to the major fruit crops. The features of this book are as follows: The first book on the novel strategy of allele mining in fruit crops for precise breeding Presents genomic strategies of mining superior alleles underlying agronomic traits from genomic resources Depicts case studies of PCR-based allele priming and Eco-TILLING-based allele mining Elaborates on gene discovery and gene prediction in major fruit crops This book will be useful to students and faculties in various plant science disciplines including genetics, genomics, molecular breeding, agronomy, and bioinformatics; scientists in seed industries; and also policy makers and funding agencies interested in crop improvement.
