“…However, 'twin seeds' can be seen regularly in most Prunus species (Kester and Gradziel 1996). Although the mechanism for this is not clear, such occurrence of twin seeds may be greatly influenced by environmental conditions (Martinez-Gomez et al 2005). It is either due to the presence of multiple eggs or twinning.…”

Plant regeneration of Prunus salicina (Japanese plum) using mature seeds was studied and evaluated. Shoots were effectively induced from hypocotyl slices of mature seeds on media containing cytokinins. Among three plant growth regulators evaluated, thidiazuron (TDZ) was the most effective for shoot induction overall. Shoots were also induced using 6-benzylaminopurine (BA), but the effectiveness was reduced at low concentrations. Low regeneration was induced using kinetin. Three plum varieties were evaluated and the regeneration appeared to be genotype dependent. Induced shoots elongated, roots formed, and plantlets developed upon transfer of the shoots to the rooting medium. Primary shoots, when sub-cultured on fresh induction medium, produced multiple shoots, and such multiplication could continue for more cycles. The plantlets were transferred to soil, and the full plants were readily recovered in a greenhouse. The regeneration process was relatively fast as plants could be recovered in 4 to 5 mo. after the culture initiation.

“…Considering the fact that several mechanisms are known to be involved in BR resistance, including phenolic concentration, thickness of the epidermis, and flesh texture, the selection should be simultaneously based on all known and unknown components. Hence, some authors [46,179] have highlighted certain imperative factors to be considered when breeding for disease resistance as: (i) the adequate knowledge of the pathogenic agent, including its virulence; (ii) the knowledge of the availability, diversity, and types of genetic resistance within the breeding program as well as within the species in exam and its close relatives; (iii) the need to handle, develop, and improve the screening and phenotyping methods, including the accurate selection of the appropriate environment for the exhibition of resistance to allow its accurate tracking.…”

“…[51,179], there could exist genetic disease control elements [180,181] to be introgressed in high-quality fruit's genetic backgrounds [40]. Hence, the relative tolerance or susceptibility of fruits to disease has often been used for selecting disease-resistant genotypes for subsequent peach breeding.…”

Peach Brown Rot: Still in Search of an Ideal Management Option

2018

View full text Add to dashboard Cite

Abstract:The peach is one of the most important global tree crops within the economically important Rosaceae family. The crop is threatened by numerous pests and diseases, especially fungal pathogens, in the field, in transit, and in the store. More than 50% of the global post-harvest loss has been ascribed to brown rot disease, especially in peach late-ripening varieties. In recent years, the disease has been so manifest in the orchards that some stone fruits were abandoned before harvest. In Spain, particularly, the disease has been associated with well over 60% of fruit loss after harvest. The most common management options available for the control of this disease involve agronomical, chemical, biological, and physical approaches. However, the effects of biochemical fungicides (biological and conventional fungicides), on the environment, human health, and strain fungicide resistance, tend to revise these control strategies. This review aims to comprehensively compile the information currently available on the species of the fungus Monilinia, which causes brown rot in peach, and the available options to control the disease. The breeding for brown rot-resistant varieties remains an ideal management option for brown rot disease control, considering the uniqueness of its sustainability in the chain of crop production.

“…Breeding efforts to improve horticultural aspects have been underway since the species were first cultivated. Recently, breeding practices in Prunus have been advanced by the development and application of biotechnology including in vitro culture (reproduction and propagation), molecular markers (identifying genetic diversity and selection of specific traits), gene transfer (protecting plants against abiotic and biotic stress) and genome mapping (analysis of important traits) (Martínez-Gómez et al 2005).…”
