What is a podcast?
For those of you who are newer to the medium, a podcast is like a pre-recorded radio show. In the same way that you turn on a talk radio show, you have to turn on a podcast. The major difference is that while our cars are equipped to find radio frequencies, they are not built to accommodate direct access to podcasts. On your smartphone or computer with internet access (since the files tend to be on the larger side), you can discover podcast shows of any kind, in any field, on any topic.
Listed above are some of the most used podcast hosts. iTunes and the iTunes Podcast app are preinstalled on your iPhone and are the simplest tools to use. You simply search for “WSU Wheat Beat Podcast” in the search bar, hit “subscribe” and the download arrow, and listen whenever it’s most convenient for you.
If you use an Android or use another type of smartphone, you will need to find a different podcasting app because those devices don’t come with a preinstalled app like Apple. If you don’t know which podcast app you’d like, simply hit the “Android” link above and it will show you to several Android podcast apps for you to choose from.
After you download an episode, you can listen without using data any time of day. Our goal is to post a new podcast every Monday. Your podcast app should automatically load our new episodes and download them for you (on WiFi), hands-free if you choose that in the app settings.
If you have further questions about what a podcast is, which app is best for you or need more assistance with getting started with podcasts, don’t hesitate to contact us.

Drew Lyon: Hello! And welcome to the WSU Wheat Beat Podcast. I’m your host, Drew Lyon, and I want to thank you for joining me as we explore the world of small grains production and research at Washington State University. We have weekly discussions with researchers from WSU and the USDA-ARS to provide you with insights into the latest research on wheat and barley production.

Drew Lyon: This week we will be discussing low falling numbers. Our first guest is Dr. Camille Steber, Molecular Geneticist with the U.S. Department of Agriculture’s Wheat Health, Genetics, and Quality Unit. Hi, Camille!
Dr. Camille Steber: Hello!
Drew Lyon: And our second guest is Dr. Kim Garland-Campbell. Kim is the USDA-ARS Club Wheat Breeder. Hello, Kim!
Dr. Kim Garland-Campell: Hi!
Drew Lyon: So we didn’t have a big problem with low falling numbers here in 2017, yet it was quite a problem last year. Is the problem going away now?
Dr. Camille Steber: I’m afraid this problem isn’t going to go away of its own accord. We’ve had to make this a breeding priority. If we do our jobs right, you’ll probably never know that we succeeded because when we have a problem year, you won’t have problems with low falling numbers.
Dr. Kim Garland-Campbell: Mm-hmm.
Drew Lyon: Ok, so do farmers need to worry about it then or is it something they should take off their worry-list?
Dr. Kim Garldand-Campbell: I think that they do need to worry about it still. Well, I don’t want to give them more things to worry about. But I think it’s something they need to consider when selecting varieties, yeah.
Dr. Camille Steber: And we have the SteberLab.org website where they can look up how varieties they’re interested in have done for falling number in the past.
Drew Lyon: Could you spell that for us?
Dr. Camille Steber: That’s S-T-E-B as in boy, E-R, lab, L-A-B, dot O-R-G.
Drew Lyon: Ok, so what priority should farmers place on this particular trait when they’re selecting varieties, Kim?
Dr. Kim Garland-Cambell: Well, I actually heard a farmer the other day tell me, you know, you can’t spray for low falling number but you can spray for stripe rust. So I think, especially if you live in an area where you get a lot of temperature fluctuations, some of the regions where we’ve seen a lot of falling number are like Mayview or Almira is another area that it is something you should take a look at.
Drew Lyon: Ok. So what are the challenges to breeding for low falling number or to prevent low falling number?
Dr. Camille Steber: The problem is that it’s actually a complicated trait because it’s really more than one problem that triggers low falling numbers. It can either be pre-harvest sprouting, which is when you get germination of the grain on the mother plant when it rains before harvest. And the other is this late maturity alpha-amylase, which is a developmental defect that occurs when you have a big temperature fluctuation during late grain filling.
Dr. Kim Garland-Campbell: And growers, I think, are used to the idea that rains during harvest can cause problems, but we didn’t realize we had such a problem with LMA in our wheat germplasm until last year, until 2016. And so now we’re conducting a massive screening effort to try and, you know, identify breeding lines that are more resistant. Right now we’re screening 40,000 heads that we harvested last summer, in spring and winter wheat.
Drew Lyon: Ok. So if our listeners out there want to learn more about low falling number, are there, where are some places we can send them for information? We mentioned that, the Steber Lab, and what was that address?
Dr. Camille Steber: Website? SteberLab.org.
Drew Lyon: Ok.
Dr. Camille Steber: And if you look for the falling number drop-down box, that’ll take you to our falling numbers website. You can also look at the small grains website. So we’re in process now, Kim and I, of doing a statistical analysis of the data over the years. So I think the small grains website will soon have a a tool for looking at how stable the falling numbers are of a variety you’re interested in.
Dr. Kim Garland-Campbell: Right. Yeah, we want to incorporate it into the variety selection tool.
Drew Lyon: Ok. So let people take a look and if that’s a priority for them help them select that. Well, excellent. Well, thank you, Camille! Thank you, Kim!
Dr. Kim Garland-Campbell: Thank you!
Dr. Camille Steber: Thank you, Drew!
