“…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]. Thus, new crossings are required to generate hybrids with the agronomic and postharvest quality of 'Camarosa', but that have other levels of resistance to pests and diseases and different responses to temperature and photoperiod.…”

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.

“…In zone and direction 3, i.e., the pedicel fruit zone, 135 0 relative to the axis (contained between the apical part and the part of the fruit attachment), the average value of the suction force was 2.16 N (group 2, Table 4). 2.38 (1) 1.86 (2) 2.26 (1) (.) Homogenous groups.…”

“…The performance of agriculture is dependent on the mechanization and automation of production. According to recent data, in the US, strawberry production covers almost 20% of the world's cultivated area [1]. The search for alternative cultivation methods in which the production process is fully automated is one of the directions of modern research.…”

“…The cost of labour related to crop production, harvesting and post-harvest activities account for the greater part of the total production costs, especially for special crops such as strawberries. The analysis related to strawberry harvest showed that, in China, the cost of strawberry harvest is over 25% of the total production cost [5], while in the USA in California, labour expenditure amounts to about 60% of the total operating costs [1].…”

Fruit and vegetable harvest efficiency depends on the mechanization and automation of production. The available literature lacks the results of research on the applicability of pneumatic end effectors among grippers for the robotic harvesting of strawberries. To determine their practical applications, a series of tests was performed. They included the determination of the morphological indicators of the strawberry, fruit suction force, the real stress exerted by fruit suckers and the degree of fruit damage. The fruits’ morphological indicators included the relationships between the weight and geometrical dimensions of the tested fruit, the equivalent diameter, and the sphericity coefficient. The fruit suction force was determined on a stand equipped with a vacuum pump, and control and measurement instruments, as well as a MTS 2 testing machine. The necrosis caused by tissue damage to the fruits by suction cup adhesion was assessed by counting the necrosis surface areas using the LabView programme. The assessment of the necrosis was conducted immediately upon the test’s performance, after 24 and after 72h. The stress values were calculated by referring the values of the suction forces obtained to the surface of the suction cup face. The tests were carried out with three constructions of suction cups and three positions of suction cup faces on the fruits’ surface. The research shows that there is a possibility for using pneumatic suction cups in robotic picking heads. The experiments performed indicate that the types of suction cups constructions, and the zones and directions of the suction cups’ application to the fruit significantly affect the values of the suction forces and stresses affecting the fruit. The surface areas of the necrosis formed depend mainly on the time that elapses between the test and their assessment. The weight of strawberry fruit in the conducted experiment constituted from 13.6% to 23.1% of the average suction force.

“…U.S. strawberry production and marketing practices vary by region (Samtani et al, 2019). For example, most California strawberries are annual plantings for fresh market (Fennimore, 2017); the Pacific Northwest is known for the production of highquality processing fruit in a perennial matted row system (Finn, 2017); and the Northeast and Mid-Atlantic states exhibit a combination of perennial matted rows and raised-bed plasticulture for fresh-market strawberries (Pritts, 2017).…”

Although agricultural plastic mulches can have significant horticultural benefits for specialty crops such as strawberry (Fragaria ×ananassa), there can also be significant economic and environmental costs. In particular, polyethylene (PE) plastic mulch requires labor and financial investments for removal and disposal. Micro- or nanoparticles may persist in soil and negatively affect microbial activity, physical soil properties, and nutrient availability. A possible alternative to PE mulch is biodegradable plastic mulch, which has similar horticultural benefits but does not need to be removed from the field at the end of the growing season. Biodegradable plastic mulch can be tilled into the soil, where it is converted by soil microorganisms into water, carbon dioxide, and microbial biomass. Although horticultural and environmental research into the impacts of PE and biodegradable plastic mulch is ongoing, it is also important to understand farmers’ practices and perceptions related to these mulches. We conducted a survey of strawberry growers in three growing regions of the United States: California, the Pacific Northwest, and the Mid-Atlantic. Our results indicate several regional differences, with California farmers being more likely to have used biodegradable plastic mulch, and growers from California and the Pacific Northwest being more likely to perceive negative impacts of PE mulch compared with growers in the Mid-Atlantic. Regardless of region, a majority of growers were interested in learning more about biodegradable plastic mulch. We conclude with several suggestions for biodegradable plastic mulch development and outreach that may promote strawberry growers’ adoption of this technology.
