Book Description
'Jeffries' is almost identical to 'Nonpareil' in tree and nut characteristics, except for unusually high productivity in certain crossing situations. Field data supports a unilateral incompatibility between 'Jeffries' and cultivars carrying the S haplotype and, consequently, suggests that the 'Jeffries' mutant expresses only one effective S-allele (S) of the putative 'Nonpareil' parent genotype (S--S8). Simple sequence repeats (SSRs) were used to assess parent-progeny relationships to clarify the true identity of 'Jeffries'. Two of nine SSR alleles tested are distinct between 'Jeffries' and 'Nonpareil', making a seedling origin for 'Jeffries' plausible. Moreover, physiological changes reportedly controlled by independently inherited, multiple genes and a significant shift for quantitative traits located on multiple, independent linkage groups provide compelling evidences that 'Jeffries' is not the result of a single mutation of 'Nonpareil'. Genotyping the 'Jeffries' S-alleles showed a band that appeared to be S-- on the gel. Its corresponding sequences strongly matched the published S-- sequences available in NCBI database. The same was true for the S8 allele. NCBI returned a hit that is 93% similar to a previously published S8-haplotype sequence. Results suggest that the genotype of 'Jeffries' is S--S8 with S---RNase present in a very low efficacy. Seed-set data taken from a large sampling of almond cultivars, including multiple cross-incompatibility groups, show a wide variability for seed sets that do not strictly follow the groupings previously established for cross-incompatibility groups. Results indicate that considerable variability in seed-sets is common in established self- and cross-incompatibility groups as well as self- and cross-compatibility groups, indicating that other genes in addition to the major S-gene are involved.

Book Description
Zusammenfassung: Almond and peach species have global importance as food crops as well as use in landscaping including restoration and reforestation. Because currently available breeding germplasm has a very narrow genetic base, genetic improvement programs are turning to wild germplasm as sources of improved quality, productivity and resistance traits. This germplasm is also enabling the dramatic modification of traditional cropping systems as with the transfer of self-fruitfulness from related wild almond and peach species to normally self-sterile cultivated almond. While presence of an extensive wild almond and related germplasm has been documented in the literature over the past century, most information remains dispersed and often not generally accessible owing to its publication in treatises and journals of limited distribution. This monograph brings together a comprehensive characterization of almond and its related species including the cultivated and wild peaches. Because it represents the only comprehensive source of information on almond, peach and their wild relatives, it represents a basic reference text of interest to researchers in both the basic and applied plant and ecological sciences

Book Description
This book brings together the latest information on almond genomics and transcriptomics, with a particular focus on cutting-edge findings, tools, and strategies employed in genome sequencing and analysis with regard to the most important agronomic traits. Cultivated almond [(Prunus dulcis (Miller) D. A. Webb, syn. Prunus amygdalus Batsch., Amygdalus communis L., Amygdalus dulcis Mill.)] is a tree crop producing seeds of great economic interest, and adapted to hot and dry climates. Domesticated in Southeast Asia, its small diploid genome and phenotypic diversity make it an ideal model to complement genomics studies on peach, generally considered to be the reference Prunus species. Both represent consanguineous species that evolved in two distinct environments: warmer and more humid in the case of peach, and colder and xerophytic for almond. The advent of affordable whole-genome sequencing, in combination with existing Prunus functional genomics data, has now made it possible to leverage the novel diversity found in almond, providing an unmatched resource for the genetic improvement of this species.

Book Description
Great progress has been made in our understanding of pollen-pistil interactions and self-incompatibility (SI) in flowering plants in the last few decades. This book covers a broad spectrum of research into SI, with accounts by internationally renowned scientists. It comprises two sections: Evolution and Population Genetics of SI, Molecular and Cell Biology of SI Systems. The reader will gain an insight into the diversity and complexity of these polymorphic cell-cell recognition and rejection systems. Heteromorphic and homomorphic SI systems and our current understanding of the evolution and phylogeny of these systems, based on the most recent molecular sequence data, are covered. Further, the book presents major advances in our knowledge of the pistil and pollen S-determinants and other unlinked components involved in SI, as well as the apparently diverse cellular regulatory mechanisms utilised to ensure inhibition of “self” pollen.

Book Description
Globally stone fruits are emerging in the market due to the increased consumer’s desire for health-promoting foods. Stone fruits attract research attention, mainly due to the cultural and commercial aspects of the array of varieties that are grown. Being grown in wide range of environments, it is very important to understand what factors influence the production and quality attributes of stone fruits. There is a lack of systematic scientific information on strategic approach for production technologies of such fruits. This book will be first of its kind focusing on technological aspects of stone fruits especially on latest developments in present day horticulture. It will be an essential reference for professionals including academicians, scholars, researchers and industries working in the said area. We hope that readers will find this book a useful resource for their research or studies, and it will be helpful in the development of high quality stone fruits in future which will improve the economic and social life of people. Besides, this book fulfills the needs of a number of horticultural courses of Universities and will serving as a pomological manual for all occasions.

Book Description
This book fully integrates the conventional and biotechnological approaches to fruit crop breeding. Individual chapters are written on a wide variety of species covering all the major fruit crops in one volume. For each crop, there is a discussion of their taxonomy and evolution, history of improvement, crossing techniques, evaluation methods, and heritability of major traits and germplasm resources. Also discussed are the most recent advances in genetic mapping and QTL (quantitative trait loci) analysis, marker assisted breeding, gene cloning, gene expression analysis, regeneration and transformation. Patenting and licensing issues are also covered.

Book Description
This book provides a comprehensive overview of almond growing from a scientific and horticultural perspective, covering botany, production, processing and industrial uses. Almonds are an important crop; they are highly regarded for their flavour, nutritional properties and culinary uses, and almond oil is used widely in food, cosmetic and pharmaceutical production. They are easy to transport and have long storability, facilitating global dissemination. Demand is constantly increasing and global production has more than doubled in the last 20 years. Authored by an international team of experts and presented in full colour throughout, this book is an essential resource for academic researchers and extension workers, as well as growers, orchard managers and industry personnel.
