Species determinations based on the closest DNA match were highly supported by existing records for ploidy and country of origin but only modestly by taxonomic keys (36%). For some unknown populations, a clear match to a standard species name could be made. But for others, the name assigned was only the closest of several similar species.

A survey assessed the performance of commercial seed cutting operations during 2021–22 to document the range of seed piece sizes planted in Washington. In addition, two field trials examined seed size performance (28, 42, 56, 70, 84, and 98 g (1.0, 1.5, 2.0, 2.5, 3.0, 3.5 oz)) for Clearwater Russet, Ranger Russet, and Russet Burbank. Seed type performance (whole vs cut) was also assessed for Clearwater Russet. As seed size increased from 28 to 98 g for all varieties and seed types, early plant growth generally improved, average tuber weight decreased by 22%, and stem and tuber number per plant increased by 77% and 50%, respectively. Cut Clearwater Russet seed produced 7% higher yields and 5% more economic return than whole seed. Economic return peaked for Clearwater Russet with a seed weight of 56 g (2.0 oz). Economic return of Ranger Russet and Russet Burbank peaked when seed size was between 70–84 g (2.5 to 3.0 oz) for Russet Burbank and at 84 g (3.0 oz) for Ranger Russet. Due to a highly variable range in cut seed size found in the commercial seed lot survey, growers may have lost an estimated $297 ha⁻¹ or $15,000 pivot⁻¹ (51 ha) during 2021–22 compared to a hypothetical potato field planted with uniform, economically optimal, seed sizes.

In the U.S. Northwest Potato Variety Development Program (NWPVDP), L/W accounts for 13% of the overall postharvest score. Selections with L/W ≥ 1.8 are preferred for maximum raw-product recovery (≥ 7.6-cm-long fries). However, tuber shape often depends on production location. Our objectives were to (1) model the effects of production location on L/W using 26 years of historical data from the NWPVDP, and (2) quantify the variability in tuber shape phenotype of selected NWPVDP varieties across production locations (WA, ID, OR). A mixed linear model demonstrated that tuber L/W was strongly affected by location, year, and location-by-year interactions (40% of total variation), while variety and variety-by-location accounted for 43% of total variation. L/W of the 227-284-g tubers of twenty-two released varieties from the NWPVDP averaged 1.65, 1.70, and 1.92 for WA, OR, and ID, respectively, and ranged from a low of 1.51 and 1.53 (<i>cvs.</i> Payette Russet &amp; Palisade Russet) to a high of 2.06 and 2.12 (<i>cvs.</i> Ranger Russet &amp; Echo Russet) across locations. The round phenotype of Palisade was stable across locations, leading to consistently low fry recovery (84% FW). By contrast, Payette tubers were invariably round in WA and OR, but elongated when grown in ID. The elongated phenotypes of Echo and Ranger from all locations ensured maximum fry recovery (94 to 95% FW), despite the relatively high variation in L/W (9–13%) attributable to location. Collectively, our results suggest an opportunity for genetic selection of L/W that are stable across locations for market specific reductions in shape waste. Future work should focus on identifying key mechanisms which are impacted by production environment for improved stability of L/W. Furthermore, cultural management strategies should be optimized for L/W consistency and usability by all sectors of the potato industry.</p></div>","PeriodicalId":7596,"journal":{"name":"American Journal of Potato Research","volume":"102 1","pages":"51 - 67"},"PeriodicalIF":1.2,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12230-025-09978-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results indicate that nitrogen fertilization significantly influences <i>M. persicae</i> populations, with intermediate nitrogen levels increasing aphid density and higher levels reducing it.

In contrast, <i>B. cockerelli</i> populations exhibited marginal responses to nitrogen fertilization, suggesting different nutritional preferences and interactions.
