“…These strengths are mainly related to the Albion cultivar and the Imported origin of transplants. Our results corroborate with Gabriel et al (2019), which studying 13 strawberry cultivars observed that Albion presents high values for fresh rmness and • Brix.…”

The multi-trait genotype-ideotype distance index (MGIDI) was used to select superior treatments in experiments with strawberries. Twenty-three productive, qualitative, physiological, and phenological traits with negative and positive desired gains were accessed in 16 treatments, a combination of two cultivars (Albion-neutral days, and Camarosa-short days), two transplants origins (National and Imported), and four organic substrates mixes (Crushed sugarcane bagasse, burnt rice husk, organic substrate, and Carolina commercial substrate). Our results suggest that most of the strawberry traits are influenced by the cultivar, transplant origin, cultivation substrates, as well as by the interaction between cultivar and transplant origin. The MGIDI index indicated that the Albion cultivar originated from imported transplants grown in substrates where the main component (70%) is burnt rice husk provides desired values for 20 of a total of 22 traits, which represents a success rate of ~ 91% in selecting traits with desired values. The strengths and weakness view provided by the MGIDI index revealed that the looking for an ideal treatment should direct the efforts on improving the water efficiency use and reducing total acidy of fruits. On the other hand, the strengths of selected treatments are mainly related to productive precocity, total soluble solids, and flesh firmness. The MGIDI index provides a unique, robust, and easy-to-handle process, standing out as a powerful tool to develop better treatment recommendations for experiments with strawberries when multiple traits are assessed.

“…The cultivar Camarosa is known for its high yield and large, firm, and tasty fruits [44]. Therefore, the superiority of hybrids regarding yield traits when 'Camarosa' was one of the parents is due to the presence of a high number of favorable alleles in this cultivar, which makes it a promising parent for strawberry breeding programs [44,45]. Currently, 'Camarosa' has been the most planted cultivar in the world, being a market leader for over twenty years [46,47], but it has sensitivity to photoperiod (short-day) and susceptibility to main diseases [45,48,49].…”

The selection of superior strawberry genotypes is a complex process due to the high variability after hybridization that is caused by the octoploid nature and the heterozygosis, making the selection of multiple traits difficult. This study aimed to select strawberry hybrids with the potential for fresh consumption and/or processing by applying multivariate analysis to obtain traits of interest simultaneously. Hybrids were obtained from the crossing among seven commercial cultivars, defining a selection of 10% of them. The experimental design consisted of an augmented block design, with two commercial cultivars, Camarosa and Camino Real, as the controls. Different variables, including the number and average mass of commercial fruits, total fruit mass, pH, soluble solids (SS), titratable acidity (TA), SS/TA ratio, reducing sugars, pectin, ascorbic acid, phenolic compounds, and anthocyanin’s, were assessed. The selection of hybrids was based on the Mulamba and Mock rank-summation index, principal component analysis, and Ward’s hierarchical cluster analysis. The selection index was based on different weights being adopted for fresh market and processing. The assessed traits had high variability between hybrids. The highest selection gains were obtained for production traits, but the different weight assignment resulted in different classifications of hybrids for both fresh consumption and processing. Most of the hybrids selected by the index remained in the same group in the principal component and hierarchical cluster analyses, which indicates that multivariate analysis is a valuable tool for assisting in the selection of superior hybrids in the strawberry crop.

“…Generally, cultivars with high TSS values are well accepted by consumers for fresh consumption. Variation observed between genotypes can be attributed to some factors, such as characteristics of the cultivar, influence of the place of cultivation and temperature(Ali et al, 2011;Hirsch et al, 2012;Guedes et al, 2013;Gabriel et al, 2019). The pH and other characteristics found in fruit can be used as indicators to define the best genotypes for the fresh market or industry.…”

Chemical and mineral characteristics, bioactive compounds and antioxidant activity of blackberries grown in an organic system

et al. 2020

Blackberry bushes have increasingly drawn producers’ and consumers’ interest since they find their cultivation characteristics, production and nutraceutical qualities advantageous. Both chemical and mineral characteristics, bioactive compounds and antioxidant activity found in blackberries are extremely relevant factors to be considered when cultivars are chosen. Chemical analyses of the nutritional composition of fruit is important, since they can help studies of quality genotypes. Besides, fruit with high nutritional values contribute to human health when they are often consumed. This study aimed at evaluating chemical and mineral characteristics, besides bioactive compounds and antioxidant activity, of different blackberry bush genotypes grown in an organic farming system in Pelotas, Rio Grande do Sul (RS), Brazil. Production, soluble solid content, hydrogenionic potential, total titratable acidity, SS/TA ratio, minerals, phenolic compounds, anthocyanins and antioxidant activity of six blackberry bush genotypes – ‘Tupy’, ‘BRS Xingu’, Selection Black 178, Selection Black 128, Selection Black 112 and Selection Black 145 – were evaluated. It was a randomized block design with three replicates of every plant. Selection Black 178 yielded fruits with the highest value of SS/TA ratio and had the highest accumulated production. The highest anthocyanin content was found in ‘BRS Xingu’. Selection Black 112 had the highest total contents of phenolic compounds and the highest antioxidant activity, whereas ‘Tupy’ exhibited their lowest values. Selection Black 178 adapted well to the organic farming system, a fact that did not happen to Selection Black 128.
