Chapter
An Introduction to Almond Species and Their Origins
Almond species, in addition to their historical importance as food crops, are becoming increasingly utilized in reforestation, ecological restoration, and urban landsca**. Their historical distribution exten...

Chapter
Self-Incompatibility of Almond Species
Commercial almond cultivars (Prunus dulcis) are self-sterile, expressing gametophytic self-incompatibility and requiring insect pollinators for cross-pollinations. Self-fruitfulness is a major objective of almond...

Chapter
Almond Species Traditional Utilization
Considerable published information on almond species utilization focuses on their potential as valuable sources for genetic improvement through the breeding of cultivars and rootstocks. A number of useful trai...

Chapter
Identification of Almond Species by Using Markers
Taxonomic classifications utilize morphological, biochemical, and molecular differences. Almond species show a particularly large variation in nut and kernel traits. These often quantitative traits are less af...

Chapter
Seed Germination of Almond Species
Almonds have hard shells (endocarps), and in some species, mechanical and/or chemical scarification, such as immersion in sulfuric acid, is required to achieve more consistent levels of seed germination. Seed ...

Chapter
Characteristics of Almond Species
Almonds and their wild relatives are grouped within the genus Prunus. Over 30 almond species and over 20 interspecies hybrids have been reported worldwide. Several reported species may be the same and are thus sy...

Chapter
Almond Species Classification
Originally classified as Amygdalus communis, cultivated almonds, as well as their close relatives, are currently classified in the genus Prunus within the order Rosales, the clade Rosids, the family Rosaceae, and...

Chapter
Enrichment of Breeding Germplasm
Related species provide adaptation to a wide range of soils and climates, making them historically important as regional rootstocks. Utilization as rootstocks ranges from top-working naturally occurring specie...

Open AccessGenome-wide association analysis and validation with KASP markers for nut and shell traits in almond (Prunus dulcis [Mill.] D.A.Webb)
Almond shell hardness is an economically important quality trait that protects the integrity of the kernel. It is directly related with shelling or crack-out percent. In the U.S. and Australian markets, soft t...

Chapter
Genome Analysis and Breeding
Almond is a nut tree species of worldwide economic importance. Almond breeding programs have been crucial to develop new cultivars that meet both environmental challenges and economic demands, always taking in...

Chapter
Epigenetic Regulation in Almond
Rapid advances in sequencing technologies have enabled researchers to reconceptualize genomes as dynamic entities with functions beyond storage and organization of genetic information. Evidence of this dynamic...

Chapter
Wild and Related Species as a Breeding Source for Biotic Stress Resistance of Peach Cultivars and Rootstocks
Cultivated peach is of global importance as both fresh market and processing cultivars and as rootstocks. Limited genetic options for breeding resistance to biotic stress is a consequence of a limited initial ...

Chapter
Genomic Designing for New Climate-Resilient Almond Varieties
During the falling temperatures of autumn, temperate tree-crop species, including almond [Prunus dulcis (Miller) Webb], activate a winter survival strategy called endodormancy to protect against unfavorably cold ...

Article
The delay of flowering time in almond: a review of the combined effect of adaptation, mutation and breeding
Regulation of flowering time in almond, as in other Prunus species, is a complex process involving both chill and heat requirements. Following exposure to appropriate consecutive periods of cold and warm temperat...

QTL map** and breeding value estimation through pedigree-based analysis of fruit size and weight in four diverse peach breeding programs
The narrow genetic base of peach (Prunus persica L. Batsch) challenges efforts to accurately dissect the genetic architecture of complex traits. Standardized phenotypic assessment of pedigree-linked breeding germ...

Article
QTL map** of pomological traits in peach and related species breeding germplasm
Peach is an economically important fruit tree crop that exhibits high phenotypic variability yet suffers from diversity-limited gene pool. Genetic introgression of novel alleles from related species is being p...

Article
Methylation of the S f locus in almond is associated with S-RNase loss of function
Self-compatibility in almond (Prunus dulcis) is attributed to the presence of the S f haplotype, allelic to and dominant over the series of S-alleles controlli...

Phenotypic diversity among local Spanish and foreign peach and nectarine [Prunus persica (L.) Batsch] accessions
Phenotypic data for tree and fruit characteristics was collected over three consecutive years from a germplasm collection of 94 peach and nectarine accessions representing both traditional Spanish as well as f...

Open AccessHeterogeneity in the entire genome for three genotypes of peach [Prunus persica(L.) Batsch] as distinguished from sequence analysis of genomic variants
Peach [Prunus persica (L.) Batsch] is an economically important fruit crop that has become a genetic-genomic model for all Prunus species in the family Rosaceae. A doubled haploid reference genome sequence length...
