Scenes from our 2023 Field day at Aroostook Research Farms in Presque Isle, ME where we showed stakeholders our first diploid crosses 🥔 from Potato 2.0 @SCRI2xPotato and USDA-ARS #potatobreeding #potato

Visited our primary dihaploid trial today, and unfortunately the flooding 🌧️ from all that rain took out three rows about a third of the way down 😢 #field season is always interesting I guess #potato #plantbreeding

PhD students and Dr. Peter Nelson working to get UAV-based hyperspectral reflectance scans on our Maine Potato Board PVY field trial today in beautiful Aroostook County 🥔 🌈 👓 🦠 @HostVirus_BII @UMaine @UMainePotato @MainePotatoes

Nanopore sequencing for viruses from 48 volunteer potato from grower fields in Maine across multiple years in full swing! 🦠 🥔 @haploidgenomics @CellBioEd @epadilla_jade @NSF @MainePotatoes @UMaineExtension

The 🌈🏳️‍⚧️🏳️‍🌈 🥔 is here! We will have these stickers available to the potato community while stocks lasts. DM me for details.

Finished planting our 2023 primary dihaploid yield trials, thanks the wonderful crew from our lab and the USDA-ARS 🥔🥔🥔 @SCRI2xPotato @USDA_ARS @MainePotatoes — we stopped for the view of Katahdin on our way to trial field 🙌🏽

Hyperspectral reflectance scanning and viral RNA day in the greenhouse with the crew, we lucked out with overcast weather today 🌈🌥️🥔🧬🦠 @UMaine ⁦@HostVirus_BII⁩ ⁦@UMainePotato⁩

We have started collecting the these sweet-smelling gift packets 🎁 from our winter crosses 😂 #potato #potatobreeding @SCRI2xPotato @UMainePotato

[E. Han Tan @ekhtn]

Found the most unexpected and pleasing behind the petal (is there’s a botanical term for this?) flower phenotype today. At first glance it looked like columbine flowers to me 🥹 #potato #solanum

A few scenes from our winter crossing block—flowers from two F1 diploid potato siblings #potato #potatobreeding @UMainePotato @SCRI2xPotato

2023 winter greenhouse crossing has begun!

[Haploid Genomics Lab @haploidgenomics]

2022 diploid F1 families to be assessed this year in the greenhouse is being readied for planting @SCRI2xPotato @UMainePotato

Happy National Potato Day! Pinto Gold and Caribou Russet from our Potato Field Day this week. 🥔🍟🌱

[E. Han Tan @ekhtn]

The application for the Assistant/Associate Potato Breeding and Genetics position at UMaine is now live! 🥔🍟🌱 #potato #plantbreeding #plantscience https://t.co/aG6RZy6k8Q

First look at ~400 primary dihaploids potato from 🧪 to 🚜 — hopefully some decent 🥔🥔🥔 come out of this

[Haploid Genomics Lab @haploidgenomics]

Congratulations to Lucas, who successfully defended his MS thesis last week! 🥔🌱🥔💉 *Photo in front of Campana elm was taken during May commencement

[Haploid Genomics Lab @haploidgenomics]

Our largest field trial yet of ~400, diverse, diploid, Group Tuberosum tissue culture plantlets destined for Presque Isle, ME this summer. Made possible by @MainePotatoes and @USDA_ARS, and in collaboration with many partners @UMainePotato @SCRI2xPotato @SbeUmaine #potatobreeding

[Haploid Genomics Lab @haploidgenomics]

Example of the wide range of phenotypes in F1 potato diploids derived from primary dihaploids, despite one of its parents being already partially inbred @SCRI2xPotato 🥔 🤯
