Quality oriented fruit breeding: Peach [Prunus persica (L.) Batsch]
Promising new tools for peach fruit quality breeding have been revised in this work. These tools included fruit quality evaluation through physical, chemical and sensorial parameters and post-harvest storage evaluation. The development of a feasible method for an early testing of peach selections generated in breeding programs is also well described together with the discussion of the inheritan...
متن کاملGenetic Control and Location of QTLs Involved in Antioxidant Capacity and Fruit Quality Traits in Peach [Prunus persica (L.) Batsch]
In peach fruits, phenolic compounds serve as a major source of potential antioxidants which are known to play a significant role in fruit quality and in human wellbeing. This study was conducted in a F1 population derived from the cross ‘Venus’ x ‘Big Top’ nectarines in order to investigate the variability in the fruit antioxidant content and to study the genetic control and location of QTLs in...
متن کاملFirst genetic linkage map of chilling injury susceptibility in peach (Prunus persica (L.) Batsch) fruit with SSR and SNP markers
Peach and nectarine (Prunus persica L) are highly perishable; they ripen and deteriorate quickly at ambient temperature. Storage at low temperature (0–5oC) is a common strategy used to slow the ripening processes and extending shelf life. However, if susceptible varieties are held too long at a low temperature, they will not ripen properly and will develop chilling injury (CI) symptoms like mea...
متن کاملJASMONATES NEGATIVELY INTERFERE WITH FRUIT DEVELOPMENT AND RIPENING IN PEACH (Prunus persica L. Batsch)
Jasmonates (JAs) are signal molecules which elicit stress responses through JAs-responsive genes; they are also involved in developmental processes, including fruit growth and ripening. In the present study, methyl jasmonate (MJ) and n-propyl dyhydrojasmonate (PDJ) were applied to peach trees at the S1, S3 and S4 phases. In all cases, both chemicals inhibited climacteric ethylene production and...
متن کاملGenotyping by Sequencing for SNP-Based Linkage Map Construction and QTL Analysis of Chilling Requirement and Bloom Date in Peach [Prunus persica (L.) Batsch]
Low-cost, high throughput genotyping methods are crucial to marker discovery and marker-assisted breeding efforts, but have not been available for many 'specialty crops' such as fruit and nut trees. Here we apply the Genotyping-By-Sequencing (GBS) method developed for cereals to the discovery of single nucleotide polymorphisms (SNPs) in a peach F2 mapping population. Peach is a genetic and geno...
