University of Florida Potato Variety Trials Spotlight: 'Red LaSoda'

‘Red LaSoda’ is a red-skinned fresh market potato standard for Florida. ‘Red LaSoda’ was first observed in 1949 as a deep red mutant of ‘LaSoda’, a progeny of ‘Triumph’ and ‘Katahdin’, in the Louisiana potato breeding program. ‘Red LaSoda’ was released by the USDA and the Louisiana Agricultural Experiment Station in 1953. Production and quality results provided here are summarized from various fresh-market trials conducted by the University of Florida’s Hastings Agricultural Extension Center from 1998 to 2019.This is a minor revision of HS323 with an added author, last updated 12/2016.https://edis.ifas.ufl.edu/hs323

University of Florida Potato Variety Trials Spotlight: ‘Atlantic’

‘Atlantic’ is a white-skinned potato, being the standard variety for chiping commonly cultivated in Florida (Figure 1). The cultivar was released as a white mutant of the USDA breeding program. It was selected from a cross of Wauseon and Lenape (UDSA seedling B5141-6). ‘Atlantic’ was released in July 1976 by the Agricultural Research Service of the USDA, the Florida Agricultural Experiment Station, the Virginia Truck and Ornamentals Research Station, the New Jersey Agricultural Experiment Station, and the Maine Agricultural Experiment Station (Webb et al. 1978). Production and quality results provided in this spotlight are summarized from various trials conducted by the University of Florida over the past 22 years.https://edis.ifas.ufl.edu/hs1278 This is a minor revision with an added author.

PSIII-6 Comparisons of high-density genomic data in Holsteins differing in coat type

Preliminary studies have reported that wild type-haired (WT) Holstein cattle have greater productive potential at a genomic level than their slick-haired (SL) counterpart. The objective of the present study was to evaluate, through a panel of commercial genetic markers (Igenity Elite, Neogen Corp), 49 Holsteins descendants SL [32 SL (n = 11 males and 21 females) and 17 WT (n = 2 males and 15 females)] from the Agricultural Experiment Station of Puerto Rico. These animals received a predictive genomic transmission capacity (PTA) based on DNA tests using more than 100,000 bovine genome markers, which contain information from their parents for a more accurate measure of genetic potential. Traits evaluated included measures of productivity, health, type and other indexes such as: net merit, milk yield, somatic cell score, among others. The data was analyzed using Proc GLIMMIX in SAS and the differences between means were determined by the Tukey test. Various subsets of animals were compared; however, no main differences were found between SL and WT (P >0.05), except for stature (-1.07±0.17 vs -0.39±0.26; P = 0.02, respectively). In a second subset, only lactating cows were evaluated (SL n = 7 and WT n = 7) and differences were found for: hypocalcemia (0.03±0.06 vs -0.21±0.06; P = 0.01), mastitis (-0.11±0.24 vs 0.90±0.24; P = 0.01), PTA type (-0.98±0.26 vs -0.11±0.26; P = 0.03), udder composite (-0.96±0.26 vs -0.07±0.26; P = 0.02), stature (-0.91±0.30 vs 0.04±0.30; P = 0.04), dairy form (-1.64±0.26 vs -0.65±0.26; P = 0.02), fore udder attachment (-0.77±0.30 vs 0.41±0.30; P = 0.02), rear udder height (-1.39±0.34 vs -0.18±0.34; P = 0.03) and width (-1.42±0.29 vs -0.17±0.29; P = 0.01), and udder depth (-0.73±0.27 vs 0.82±0.27; P = 0.002), respectively. These results suggest that SL males and females are genomically similar to WT for the most important economic traits when descending from a SL dam and when compared as a single group. However, differences in type and health traits may occur if the females are compared alone.

Old and new plants from the Americas to Europe: potatoes, corn and the genetics of double hybrid corn (1800–1940)

We discuss the extension of corn and potatoes in Galician Atlantic agriculture during the nineteenth and twentieth centuries as an innovation process that facilitated rapid circulation of a new cattle feed from the Americas to Europe. Specifically, we focus on Galicia from 1890 to 1940, a time of significant scientific interest with regard to genetic improvements. This new science made it possible to develop double hybrid corn plants that became widespread after the 1920s. In this article we will describe the conditions accompanying the introduction and spread of these American crops, as recorded by modernist historiography, then analyse the institutional and social framework – knowledge networks, innovation systems and institutional and social tools – that enabled genetic advances in the twentieth century. To accomplish this, we must trace the journey of seeds and knowledge across the Atlantic from places such as the Connecticut Agricultural Experiment Station (1918) to the Galician Biological Mission (1921), among others.

Preference for and Sensitivity to Flavanol Mean Degree of Polymerization in Model Wines Is Correlated with Body Composition (P06-100-19)

Objectives It is known that the degree of polymerization (DP) of flavanol compounds influences the perceived bitter and astringent sensations of flavanol-rich foods. Previous research has indicated that preference for bitterness and astringency is related to health status (i.e., obesity) and sensitivity to bitter compounds such as 6-n-propyl-thiouracil (PROP). The objective of this study was to examine trends in liking, bitterness intensity, and astringency intensity of wine-like products with distinct flavanols of different DP in a consumer sensory panel when consumers were differentiated by phenotype. Methods Recruited panelists (n = 102) were segmented into different phenotypes based on body fat percentage (BF%), body mass index, PROP sensitivity, and stated preference for bitter foods. Differences in overall product liking, perceived bitterness intensity, and astringency intensity were observed between the three wine samples formulated to contain varying flavanol mDP. Results Considering the panelists altogether without segmentation, overall liking and bitterness liking decreased with increasing flavanol mDP, with concurrent increased perception of bitterness and astringency intensity. When looking at specific phenotypes, subjects of higher BMI and BF% showed significantly reduced ability to detect differences in bitterness and astringency intensity. Interestingly and unexpectedly, PROP sensitivity and self-reported bitterness preference did not significantly correlate with liking and intensity trends based on flavanol mDP. Conclusions Overall, these data suggest that BF% and BMI are greater predictors of liking and sensitivity to flavanol-rich foods compared bitterness sensitivity and self-reported bitterness liking. Reduced perception of bitterness and astringency associated with weight gain may impact selection and preference for these foods.
