Progeny testing, both formal and informal, has been a component of the University of Florida strawberry breeding program. Informally, the potential of numerous parental combinations has been assessed by growing small populations of each combination, and then ranking these populations according to visual impression. Formal progeny testing, where variables are measured on seedlings in a replicated measurement block, was used during the 1987-88 season. Several families were identified as promising, based on an analysis of yield, fruit size, firmness, and appearance data.

Ethephon solutions at various concentrations were sprayed on strawberry plants, Fragaria × ananassa Duch., in late fall to determine if fruit yield was affected in the subsequent growing season. Plants of the day-neutral (everbearing) cultivar Centennial sprayed with 100 ppm solution had increased fruit yield and number compared with control plants. Selection 107 M 6 from the University of Guelph strawberry breeding program produced greater fruit yields with a 1000-ppm spray but fruit number was not increased. Yield and fruit number of Redcoat and selection 31 B 38 were not affected by ethephon sprays.Key words: Strawberry, ethephon

Strawberries are one of the most important food crops grown in Florida, with a harvested area of ≈10,000 acres. The University of Florida strawberry breeding program develops cultivars adapted to this region and its particular weather conditions, with a major aim of increasing overall quality. The objective of this study was to compare the fruit of advanced breeding selections to those of commercial cultivars, for compositional attributes. Seven different strawberry genotypes were compared at harvest and after 7 days at 4 °C across multiple harvest dates during two consecutive years. Compositional attributes were highly influenced by year, harvest date within a year, genotype, and storage. Overall, compared with other genotypes, selection FL 09-127 exhibited consistently higher soluble solids and total sugar (TS) contents at harvest and after cold storage. Higher ascorbic acid (AA) and phenolic contents at harvest were observed in selection FL 07-193. However, its anthocyanin content was among the lowest. In contrast, FL 10-47 exhibited relatively low AA content at harvest but consistently high total anthocyanins (TACs) and total phenolic (TP) contents after storage. Overall, results from this study provide valuable information to the breeding process by identifying new genotypes with improved compositional attributes combined with suitable quality characteristics after cold storage.

The effect of various parents on the degree of powdery mildew resistance in strawberry progenies was studied. Puget Beauty parentage, compared with Siletz, Surecrop, Talisman, Magoon, or Stelemaster parentage, gave a highly significant increase in the mean resistance rating. British Sovereign parentage, compared with Northwest or Agassiz parentage, gave a significant increase in the mean resistance rating. Puget Beauty was the only parent to give relatively large numbers of seedlings immune or resistant to powdery mildew. Siletz was as resistant to the disease as Puget Beauty, but did not transmit this resistance to its progeny. Selections immune or resistant to powdery mildew will be used in the strawberry breeding program at Agassiz.

This study estimates the proportion of rice yield increase in University of Arkansas Division of Agriculture's (UofA) released rice cultivars that are attributable to genetic improvements through the University's breeding program. Test plot data from eight UofA experiment stations were used to quantify the yield increases and potential yield growth decreases over time. In addition to quantifying the yield and yield variance evolution at the UofA, this study also calculates the economic benefits of the UofA rice breeding program. Results indicated that by releasing modern rice cultivars, the UofA rice breeding program increased average producer yield by 0.68 bu/ac annually. During the last decade, 1997-2007, the average annual economic benefits were 34.3 million (2007) dollars. When accounting for the spillover of UofA rice varieties to neighboring states the average annual economic benefit of the breeding program increases to 46.7 million (2007) dollars.

The University of Arkansas (UA) blackberry breeding program began in 1964, with the aim to provide high-quality fruit to the fresh market industry. One of the important traits for successful blackberry (Rubus subgenus Rubus Watson) postharvest handling is flesh firmness, so developing cultivars with high firmness is a top priority for the fresh market blackberry breeding programs across the world. In particular, the Arkansas blackberry program has a wide range of genotypes with exceptional firmness characteristics, including fruit with a unique crispy texture and firmness. During 2013 and 2014, fruit firmness measurements were done on 15 Arkansas genotypes including those with crispy and noncrispy textures. Firmness measurements consisted of fruit compression, skin drupelet penetration, and receptacle penetration. Confocal photos were taken on sections of berries of a subset of crispy and noncrispy genotypes, and color reversion was evaluated among these genotypes after storage. Compression force values differentiated crispy and noncrispy genotypes, with average values of 11.8 Newton (N) and 8.0 N, respectively. Drupelet penetration force was also higher for crispy genotypes averaging 0.23 N and noncrispy 0.15 N; similarly, receptacle penetration force averaged 0.20 N for crispy and 0.18 N for noncrispy genotypes. Visual inspection of fruit tissue revealed that drupelet mesocarp cells and receptacle cells and cell walls of crispy genotypes maintained their structure during ripening and did not break apart, whereas noncrispy genotypes did not maintain their structure and cellular integrity. Color reversion is a postharvest disorder in which drupelets of blackberry fruits turn red after being black at harvest. Therefore, it has a negative impact for growers, shippers, and consumers. After storage at 5 °C for 7 days, crispy genotypes expressed low levels of reversion compared with noncrispy genotypes. For crispy genotypes, 13.2% of drupelets developed color reversion, whereas a 41.0% developed this disorder in noncrispy genotypes, implying a better postharvest potential of this texture.
