“…has a unique musky aroma, and the plant has a strong tolerance to stress and a robust plant morphology. Breeders have exerted considerable efforts into the applications of breeding this germplasm resource (D avalos-Gonz alez et al 2022;Horvath et al 2011;Marta et al 2004;Olbricht et al 2021); however, further improvements are required for commercialization. Additional studies on hybridization can be conducted on other related species.…”

Most strawberry plants have white flowers and red fruit. We developed a new strawberry selection with pink flowers and white fruit, and named it G23. Basic phenotypic data were recorded over years of observation and experimentation with the flower crown diameter, petal color, and rate of fruit set, as well as fruit skin color, flesh color, seed color and attachment status, fruit weight and shape, soluble solids contents, and firmness. We found that G23 bloomed with a stable pink flower and produced white fruit consistently with a relatively high fruit-set rate compared with its female parent, ‘Pink Panda’. G23 displayed high resistance to Fusarium wilt (Fusarium oxysporum) and anthracnose (Colletotrichum spp.). It is also tolerant of high temperatures (up to 40 °C) and long-term drought. The asexual propagation ability of G23 is high, with ∼60 to 100 stolon ramets formed during the summer. In summary, this new pink-flowered and white-fruited strawberry germplasm is suitable for ornamental use, as a result of its remarkable flowering and fruiting characteristics. In addition, it provides opportunities for innovative strawberry germplasm for future breeding.

“…As a corollary of the information gathered from the available literature on the subject under discussion, it was evident that genetic improvement in strawberries was fundamentally aimed at increasing productivity, the sensory quality of strawberries, and adaptation to various environments [9], and in certain countries, there were also relevant experiences in the formation of varieties with resistance to root diseases [71,135], foliar diseases [11] and to viral complexes [74]. Among the wide genetic diversity existing in the 26 species, only a part of the reservoir has been used, basically from Fragaria x ananassa [11], infrequently, from other octoploid species [74,136], and exceptionally, with a lower of ploidy level [128].…”

The growing increase in global strawberry production and consumption has been spectacular during this century. In 2019, 396,401 ha were planted, and 8.9 million tons of fruit were produced globally, and more than 50% of that volume was in the subtropical climate. The problems and losses caused by diseases and pests are of global importance, particularly with root and crown diseases, the severity and spread of which has been magnified by the cancelation of certain soil fumigants, and by the susceptibility to one or more of the parasites of the group of cultivars currently planted. The use of the genetic reservoir available both in the cultivated species, as in the 26 wild species, is a formidable wealth of genes, partially collected, and characterized, which can be of fundamental importance to introduce new genetic combinations into modern commercial cultivars and to redesign them, so that they have a greater adaptation to stresses caused by biotic and abiotic factors, in addition to an important improvement in the nutraceutical quality of the fruit. This chapter documents the importance of this gene pool in the development of elite cultivars with these qualities.

“…Therefore, introgression with the cultivated strawberry F. ×ananassa seams reasonable. However, there are substantial difficulties in interspecific hybridisation due to ploidy differences and other incompatibilities [50]. Pre-breeding experiments next to already published synthetic polyploids [51] are necessary first.…”

Prior to the world-wide dominance of F. ×ananassa in strawberry production, native species had been cultivated in European gardens for centuries. Especially the musk strawberry (F. moschata) had been highly appreciated due to its fruit size and extraordinary aroma. Detailed studies on the diversity of the species’ fruit aroma are lacking, although breeding aims to improve strawberry aroma by complex crossings during recent years. Today a few cultivars, abandoned synanthropic occurrences and native populations of this species exist in Germany. Here we characterised aroma profiles of F. moschata accessions by analysing Volatile Organic Compounds. In particular, differences between native and cultivated accessions as well as the diversity in aroma profiles of native populations were investigated. Profiles of Volatile Organic Compounds were analysed by immersion stir bar sorptive extraction-gas chromatography-quadrupol mass spectrometry (imm-SBSE-GC-qMS). These data were compared with a genetic characterisation of samples based on eight microsatellite loci using univariate and multivariate statistical analyses. High amounts of furanones and the key compound methyl anthranilate were characteristic for the aroma profile of F. moschata. We detected a considerable diversity of Volatile Organic Compounds among accessions of F. moschata, particularly among genetically distinct samples from the same population. Native accessions contained more terpenoids but less esters and were moderately differentiated from cultivated samples. The observed patterns of Volatile Organic Compounds indicate that cultivated accessions had been selected for favourable aroma profiles and thus showing traces of domestication. Moreover, native populations harbour a great diversity of Volatile Organic Compounds, which could be also considered for future breeding efforts.
