What is the Spanish term for a mature maize plant that lacks ear shoots? (Barren in English) Mexican Spanish is most immediately relevant, but I'm also interested in other dialects!

@adeelzafarpbg # of ears where 1+ kernels were set/# of pollination attempts. I figure there's some human error involved too. 🥵 Each point represents 1 accession on 1 day. Sometimes that captures 1 pollination attempt, other times it captures 200+. I'm just beginning to explore the data. 😎

@vbern Cool, but do you really mean pollination or fertilization or seed setting?

11 years of Ames 🌽genebank hand pollination data plotted against maximum daily air temperature. Pollination success does indeed decline above 95F/35C. 🥵

Now with jitter to better illustrate point density.

@cityofames @BunchBikes Thanks!

@vbern @BunchBikes We will have staff check into this. The winds yesterday blew a lot of snow back on west and north sides of roads and paths. Thanks for letting us know!

Would be really great if the @cityofames could plow the bike lane along State Ave so i could get to and from work safely. #BikeCommuter

Change "starts with changing what we grow, how we grow it, and who benefits. And it could not be more urgent." - @PowerUSAID, @USAID #FoodPrize22

„Crop Trust is a climate change organisation“ says @CaryFowler_ , Special Envoy for Global Food Security at US State Department at #FoodPrize22

Dr. Fowlers work has inspired the direction of my career and much of my research with genetic resources. It was great to finally hear him speak in person, especially as the opening speaker at the @WorldFoodPrize #BorlaugDialogue in Des Moines. #FoodPrize22

@MichaelTom8o @USDA_ARS @Michelle_Heck1 @Chemistophe Those begonias. 😍

On my first official work trip for @USDA_ARS. Do these views ever lose their charm?

JOIN: Training course on vegetable genetic resources conservation and use TOPICS: germplasm information collection and management; landscape genomics study and analysis; and information sharing on crop regeneration (amaranth, malvaceae, solanaceae, and cucurbits).

@Evwool No--they will freeze outside where I live or basically melt at temperatures above 29C. Activity is significantly reduced below 13C.

@vbern We've only started keeping worms a few months ago. Ours are indoors. Did yours cope with the cold?

They worked hard this winter. ❤️🪱 #vermiculture

@Ballykae @FranklinHabit I imagine this practice was also much more common before the Euro was adopted (1998).

@Ballykae @FranklinHabit I took a trip to Iceland with my grandma in 2019. She is a well traveled lady who lived abroad in the 90s. Yet, she pulled a fat wad of greenbacks out at the grocery store (where we bought yarn 😁). Luckily, I was there to intervene-- the cashier was dumbfounded.

@Yan_Geneticist We do not have this requirement in our quarantine greenhouse on campus. 🫣

Hi guys, when you grow transgenic corns in greenhouse, have you been asked by the USDA-APHIS to collect all the water waste from irrigation and sterilize it?

@addie_maize @isuagronomy @USDA_ARS I really appreciated the way you opened your talk!

PROPS to Jamie O’Rourke and Michelle Graham for proposing and organizing this session, and also @vbern, for helping to ensure the meeting program included diverse perspectives! @isuagronomy @USDA_ARS

I'm so very impressed with @NAPlantBreeders and the diversity dinner this evening. @CyDiversity and all the speakers were excellent. I can't effectively relay how happy I am that NAPB has included this session and these topics -- well done!

The feeling when an undergrad you worked with during your PhD is presenting a poster at a conference your (our!) field. youtu.be/R9jnzuwCT78 😍🥰
