 Well, good morning and thank you for the invitation to speak today at the virtual field day for the Langdon Research Extension Center My name is Andrew Green. I'm the spring wheat breeder at NDSU and I'd like to talk to you just a little bit about a variety review from data that's unique to the Langdon area over the past few years and you know, I'd rather be standing in a field and discussing these things with you and Be able to walk through and look at lines and see how they're doing this year But in some ways even though this virtual format is different, you know We're able to do some things that we wouldn't have been able to do otherwise And one of the things I thought might be interesting is to share Some of this data with you that I would have used to compile my presentation where I there at the field day But to be able to really get a closer look at what Is going on and be able to see some things that we wouldn't be able to see from the tour wagons so What we're looking at here is a figure that's showing a comparison of yield by protein Protein on the y-axis here would be higher as you go up and the same with yield the further to the right We would have higher yields So in the top left corner would be things with a high protein and a low yield and In the bottom right would be things with a high yield and a low protein So what do we see from this kind of a figure? well, the first thing we notice as you would probably expect is that the negative relationship between yield and protein is pretty evident We know this because we know that typically high yielding lines have tend to have lower protein and vice versa but what I'd like to show you is that there are plenty of lines that Don't follow this trend exactly and the way that I've chosen to share this with you is with a Set of numbers that are called best linear unbiased predictions now This is a very similar mathematical approach to what's used to calculated estimated breeding values or Estimated progeny differences in cattle these approaches we got from the animal science folks and so A high blup value for a trait like grain yield might be analogous to you know a high Estimated breeding value for you know milk yield or other things like this. So That's why these numbers yield in particular is on a scale from minus 15 to 15 the average yield of all the lines in this comparison is at zero So if you look at the average for yield and protein The average falls somewhere around that X that I just drew where there's a cluster of lines right in the middle of a figure So if you go higher then this line For protein and higher to the right of this line for yield you have things that are Higher than average yield higher than average protein. So these things are reversing the trend From what we would normally see which is a strong negative relationship So Dynagro ambush a C Goodwin M. N. Torgy N. D. Frohberg Mott which is not a very traditional Northeastern North Dakota line, but has performed well in the Langdon area These are things that have had Good yields with good proteins. So what do we have down here in this corner? We have high yield low protein. Does that necessarily mean that the quality is bad? Not necessarily, but there's a pretty strong chance that the end-youth milling and baking quality Won't be as good on these lines. We can find ways to look that up using our Variety trial results an extension guide that's released every fall that has all this annual data in it So the quadrant of the graph that we would really ideally like to be in is up here top right high yield high protein a Lot of your racehorse varieties are and a lot of these are very familiar to many of you are down in this category Again doesn't guarantee the quality is bad, but it means that the protein might get low in a year where the yields are high Where do we want to stay away from we want to stay out of? This quadrant this corner down here in the bottom left would be low yield and low protein not a good situation this quadrant up here in the top left is strongly lower than average yield and strongly higher than average protein So if you're looking for really high protein and you don't mind Low yields relative to the rest of the trial you might be looking in this area right up here and Technically that would apply to all of the things that are all the way in this square But as you get closer to the middle of this cluster here This these lines here are what you would consider to be sort of average in many ways in the trial The things in the bottom right hand corner as you get further and further away Those are exceptionally different Okay, so what do we have in the quadrant of lines that? where we would like to be Dynagro ambush, this is a line that has had pretty strong yield performance in this area has mediocre BLS bacterial a streak and fusarium headlight resistance and The end-use quality is not too bad so One you're probably gonna have to monitor for diseases, but overall it's tested pretty well AC good one, this is a Canadian line that is not quite available to Farmers in North Dakota yet. I think there's a possibility that it could be in future years and Then Tori that's a line from the Minnesota program that was just released Pretty strong quality on this line the stability and the absorption not too bad low volume wasn't as good as it could be but Certainly average to above average With pretty good disease resistance overall on that line as well Andy Froberg is a new release from our program that has very good quality and As far as diseases go it's moderately resistant to Bacterial leaf streak to scab to the rusts Again something that When it's outside of that normal trend line above average for both yield and protein might be worth taking a look at So the corner that I would really encourage you to think twice about again is down here in the bottom right We're not guaranteed to have poor quality here, but you really need to look at your Variety trial results an extension guide to see and if you're gonna only look at three categories the three that you've heard me Mentioned so far that I would really say you could seek out and try to stay as high as you can Frenograph absorption, which is basically water absorption of the flower the stability which is a measure of the strength of the dough and Then loaf volume, which is just literally measuring that Physical volume of the miniature loaves of bread that are baked during testing if it's got high marks for those and the grain protein stays good It's probably a pretty decent quality line So low protein doesn't guarantee low quality but in the cases of a few of these lines like LCS trigger LCS Nitro the quality is Has not been good Things that you really would want to think twice about despite the fact that they've got this Extremely high yield potential. I would work your way back toward the pack here on some of the lines that are in this area if you're looking for really high yield potential and sort out those that have the disease resistance that's important to you and Also possessing good end-use quality. So there's way too many lines to go through and talk about them all Individually, but this is how I would encourage you to break down and think about What what's important to you and why? that results guide again is going to have the most up-to-date information on diseases for bacteria leaf streak what we're finding is that Anything greater than a seven a seven or higher You're looking at a pretty strong chance of decreased yield potential in an in an environment where that disease is present for fusarium head blight You're going to probably Ideally like to be in the four or less rating the fives and sixes or lines that you're going to have to monitor your risk And look at the scab forecasting models to make fungicide decisions Anything a seven or greater. You're looking at a pretty risky scenario for Development of the disease And so I would really encourage you to think carefully about Things that are a seven or higher on that scale that we that we release Those are the things that I think are important for making variety decisions again I'm not necessarily trying to highlight or pick on anything in particular With this figure, but again just showing you that there are things out there that have Higher than average yield with with good strong quality profile and decent straw this is This scale here grays and blues are good for straw string other red dots or problems things that might be Have poor straw and so we've got different ways of manipulating this data I'll show some of these types of things at winter meetings But if you have questions about Varieties or you're curious about interpreting the quality data or you're interested in learning more about this breakdown I've got here of of yield versus protein and things like that. Please don't hesitate to reach out to me My number my information is on the NDSU website. You can call me. You can email me If you want to just visit about the things you think we should be doing in the breeding program, that's fine, too But give me a call and I'd love to talk to you about it and hopefully Things will be a little bit more back to normal by this time next year and we can get together and talk about something similar In a wheat field, so thank you, and I hope you enjoy the rest of your tour
