“…Pulp firmness did not correlate significantly with any other variables. This disagrees with the results found by Murti et al (2012), for which pulp firmness was significantly correlated with color of the epidermis and soluble solids content of the fruits.…”

“…The fact that there was no difference between the genotypes studied for pulp firmness was contrary to the expected one, considering that there is a wide variability between different populations of strawberry for this characteristic (Hancock et al, 2008) and it is subject to high selection gain in breeding programs, and may reach more than 50% gain per selection (Murti et al, 2012).…”

Strawberry cultivation requires the use of cultivars adapted to the temperature and photoperiod conditions of the production region. The objective of this work was to evaluate cultivars and advanced selections of strawberry on productive performance and fruit quality, under the conditions of South Plateau of Santa Catarina State. The experiment was carried out in the municipality of Lages, in the 2016/2017 growing season. The cultivation system used was in the soil, in beds covered with black polyethylene film. The cultivars Camino Real, Benicia and Pircinque, and the selection CE 56 obtained the highest yields, above to 30 t ha-1. Benicia, Camino Real and Monterey, in turn, obtained the fruits with higher average fresh weight, around 24 g fruit-1. In the selections CE 51, CE 56, FRF 57.6, LAM 119.1, FRF 104.1, FRF PA 109.2 and the cultivars Benicia and Monterey the fruits of better quality were achieved, expressed by values of soluble solids / titratable acidity ratio above to 13. The cultivars Camino Real, Benicia and Pircinque, and the selection CE 56 performed as the most adapted to the region of study, among the genotypes evaluated.

“…Whitaker et al 2012when studying 15 experimental hybrids and two parents ('Radiance' and 'Elyana') in two locations (Balm and Dover, in Florida) observed the heritability in the broad sense for Sh with low (h² = 0.18±0.03), for average fruit weight with medium to high (h² = 0.53±0.04) and for the other analyzed traits with a median value (h² = 0.30 to 0.41) supporting themedium to high heritability values of some traits in the present study. Murti et al (2012) reported that estimates of heritability (h²) for F 1 populations and 8 parents used as parents ('Akihime', 'Sachinoka', 'Keumhyang', 'Seolhyang', 'Maehyang', 'Soogyeong', 'DNKW001' and DNKW002 ') was 0.498 for fruit firmness and 0.678 for soluble solids content, in a study conducted at the National University of Gangneung-Wonju, Korea, values close to those found in the present study.…”

The most efficient breeding strategies in crop improvement is the selection based on heritability and combing ability estimates for the traits of economic importance or commercial value. Therefore, the present study was to obtain estimates of heritability and to estimate the phenotypic and genotypic correlations among the characteristics of interest. The commercial cultivars ‘Aromas’, ‘Camarosa’, ‘Dover’, ‘Festival Flórida’, ‘Oso Grande’, ‘Sweet Charlie’ and ‘Milsei-Tudla’, and 103 F1 hybrids from the crossbreeding experiments were evaluated for four traits of commercial fruit yield and 13 traits of fruit physical and chemical quality. The estimated genetic parameters were general combining ability, specific combining ability, genotypic correlation among traits, estimates of heritability, genetic and phenotypic variance. The ‘Camarosa’ and ‘Aromas’ cultivars were the most promising cultivars for use as parents in the commercial fruit production, while ‘Dover’ and ‘Sweet Charlie’ cultivars were selected for taste of fruit in strawberry breeding, as they showed higher concentrations of favorable alleles in the F1 hybrid population. It was also verified some strong genetic correlations for some pairs of characteristics in the present study that may allow indirect selection. The estimation of these parameters is an important basis for decision making on the genetic engineering of strawberry.

“…The genetic base in the cultivated strawberry is relatively narrow (Sjulin and Dale, 1987); however, high levels of heterozygosity in the strawberry genome and the hybrid nature of F. •ananassa (Hancock, 1999;Maas, 1998) make breeding for disease resistance a viable option. Despite much knowledge on fusarium wilt diseases in other crops, little is known of the genetics of resistance in strawberry, where most inheritance studies on strawberry populations have been on fruit traits (Murti et al, 2012;Shaw and Sacks, 1995;Verma et al, 2003). From a study in Japan of Fof resistance in strawberry, Mori et al (2005) reported bimodal segregation of disease resistance to fusarium wilt in F 1 hybrid seedlings of strawberry and concluded that major genes were involved, but there was also a multigenic component, because among susceptible cultivars, the disease severity index varied continuously.…”

Fusarium wilt of strawberry, incited by Fusarium oxysporum f. sp. fragariae (Fof), is a major disease of the cultivated strawberry (Fragaria ×ananassa) worldwide. An increase in disease outbreaks of the pathogen in Western Australia and Queensland plus the search for alternative disease management strategies place emphasis on the development of resistant cultivars. In response, a partial incomplete diallel cross involving four parents was performed for use in glasshouse resistance screenings. The resulting progeny were evaluated for their susceptibility to Fof. Best-performing progeny and suitability of progenies as parents were determined using data from disease severity ratings and analyzed using a linear mixed model incorporating a pedigree to produce best linear unbiased predictions of breeding values. Variation in disease response, ranging from highly susceptible to resistant, indicates a quantitative effect. The estimate of the narrow-sense heritability was 0.49 ± 0.04 (se), suggesting the population should be responsive to phenotypic recurrent selection. Several progeny genotypes have predicted breeding values higher than any of the parents. Knowledge of Fof resistance derived from this study can help select best parents for future crosses for the development of new strawberry cultivars with Fof resistance.
