Rose (Rosa × hybrida L.) Breeding—An Old Flower for a New Age
摘要
Garden rosesRose (Rosa × hybrida L.) areBreeding amongstFlower the favorite landscapingLandscaping, cut and potted ornamental plantsOrnamental plant, cultivatedCultivated on both hemispheres and five continents. Due to extensive natural and artificial hybridizationHybridization over the long period, a plethora of roseRose varietiesVariety have emerged, showcasing diverse flowerFlower colorsColor, shapesShape , and distinctive fragrance notes. In the contemporary context of pronounced environmental awareness, there is a market demandMarket demands for healthy plants that require minimal pesticide usage. Consequently, in the field of roseRose breedingBreeding, significant emphasis is placed on developing resistanceResistance to diseases, toleranceTolerance to varying temperatures, and adaptability to extreme environmental conditions. The ongoing process of breedingBreeding garden rosesRose is characterized by a continuous evolution, with current breedingBreeding goals shifting from purely aesthetic considerations to a more environmentally and wildlife-friendly approach. The focus is on contributing to urban ecosystem services concomitantly aligning with SustainableSustainable Development Goals (SDGs). The most common method for roseRose breedingBreeding is planned hybridizationHybridization, whereby by crossing parents with different characteristics, offspring with the desired characteristics can be predicted and obtained. Due to the different ploidyPloidy levels and pollen-related poor fertilizationFertilization and seedSeed formation failures are common in the roseRose breedingBreeding process. Somatic embryogenesisSomatic embryogenesis, embryo rescueEmbryo rescue as well as in vitro mutagenesisMutagenesis albeit not represented enough, can help in overcoming hybridizationHybridization limitations. Additionally, conservationConservation and sustainableSustainable usage of genetic resourcesGenetic resources fortified by novel techniques for mapping the genesGene of interest—marker-assisted selectionSelection and/or AgrobacteriumAgrobacterium tumefaciens-mediated plant transformation can lead to the development of unique cultivarsCultivars. Future roseRose breedingBreeding plans should consider multiple added valuesAdded value through the selectionSelection of cultivarsCultivars that are both ornamentalOrnamental and edible, concomitantly meeting several important societal needs.
