| Abstract | ||||
| Peaches [Prunus persica (L.) Batsch] are ranked third in the world as one of the most important temperate fruit tree crops from an economic standpoint. Selecting low-chill genotypes suitable for the climate of a warm winter growing region, which is expected to worsen as global warming causes reduction of accumulated winter chill, is essential for maintaining peach production and quality. Local Egyptian "Mit-Ghamr" peach is the principal cultivar grown in Dakahlia governorate, which includes many genotypes as they are usually propagated by seeds, where such genotypes which generally have a special taste and aroma vary greatly in phenological and yield traits within a single orchard. Therefore, the present study aims to assess phenotypic variability and molecular diversity of a native distinct peach germplasm collection adapted under Egyptian conditions for optimal utilization of genetic resources in confronting the negative impacts of climate change. Nine selected Egyptian peach genotypes; eight representatives of genotypes commonly known as Sultani “early, intermediate, and late maturing”, Shamy, Hegazy, Mawy, Fark, and Neely, in addition to a newly selected one named “Wardy”, were tested. A total of forty phenological traits were used for differentiating the nine selected Egyptian peach germplasm. For molecular characterization using microsatellite, ten specific SSRs primer pairs were analyzed for genotyping of the Egyptian peach collection. Data showed a broad sense of variation at the level of measured morphological traits combined with genetic criteria, which is useful for purposes of improvement through breeding programs, preservation, optimal utilization and management of Egyptian peach germplasm collection. | ||||
