Purdue to obtain knowledge on 1,200 soybean varieties from breeders in 11 states
WEST LAFAYETTE, Ind. – Lately, Purdue College’s Katy Rainey and Keith Cherkauer have labored to foretell soybean biomass from drone imagery in Indiana.
“We’re now increasing that functionality to all the general public soybean breeding packages within the area,” mentioned Rainey, professor of agronomy, who additionally directs the Purdue Soybean Heart. Quickly, she and Cherkauer will start receiving drone imagery collected on a panel of 1,200 soybean varieties that breeders have planted in 11 states throughout the U.S. north-central area.
“Right here at Purdue, we’ll do all of the processing and modification of the photographs to foretell biomass,” she mentioned. The trouble is a part of the SOYGEN3 (Science Optimized Yield Positive factors throughout ENvironments) venture. Consisting of eight universities, together with Purdue, SOYGEN3 has greater than $900,000 in funding from the North Central Soybean Research Program.
“The overarching aim on this experiment is to develop strategies and fashions for choosing soybeans that shall be excessive yielding in future excessive environments underneath climate-change eventualities,” Rainey mentioned. “We all know that the long run environments we’re going to develop soybean in are completely different from those now we have now as a result of local weather is altering. We’re getting extra excessive climate, as nicely, from local weather change.”
The venture exploits software program, referred to as Plot Phenix, which quickly converts aerial crop pictures into helpful info for plant breeding, crop modeling and precision agriculture. Rainey and Cherkauer, professor of agricultural and biological engineering, and Purdue PhD alumnus Anthony Hearst, CEO of Progeny Drone Inc., patented Plot Phenix in 2022.

“I’m all in favour of water use, the results of environments, and the flexibility to measure and simulate soybean throughout massive areas,” mentioned Cherkauer, who additionally directs the Indiana Water Resources Research Center. “Having areas which might be farther aside will increase the probability that we are going to have a spread of environmental circumstances.”
Minnesota soybean breeders and farmers plant completely different genetic inventory than these in Indiana, for instance, which requires extra heat-resistant varieties. However even areas that share the identical annual common precipitation may expertise dramatically completely different years.
“We may have drought right here in Indiana, and japanese Kansas could possibly be having a standard 12 months. Accessing so many areas that could possibly be experiencing common climate circumstances and drier circumstances permits us to stretch the picture evaluation and the fashions we’re constructing past what we do proper now,” Cherkauer mentioned.
Japanese Kansas will get about the identical precipitation as Indiana, Illinois and Missouri. However western Kansas receives about half as a lot precipitation. It resembles central-western Nebraska, the Dakotas and western Minnesota in that regard.
“Indiana is sort of totally rain-fed aside from seed manufacturing and manufacturing within the sandy soils. Illinois goes to be comparable. As you get into Iowa, they’re beginning to see a bit extra irrigation,” Cherkauer mentioned.

Cherkauer is a co-founder of GRYFN, a Purdue-affiliated firm that has offered a brand new drone for the venture with funding from the departments of Agronomy and Agricultural and Organic Engineering and the School of Agriculture. Calibration flights for the brand new platform have already begun at Purdue’s Agronomy Center for Research and Education, a 1,600-acre farm facility situated seven miles northwest of campus.
The SOYGEN3 collaboration will fly drones that accumulate imagery in purple, inexperienced and blue (RGB, or true colour, the kind captured by common cameras).
“SOYGEN3 is about beginning with comparatively cheap cameras and {hardware} methods at a wide range of areas,” Cherkauer mentioned. However the Purdue drone additionally will carry multispectral and thermal cameras, yielding higher knowledge units that might result in suggestions for his or her SOYGEN3 companions.
Such knowledge may assist the U.S. keep its place because the world’s main soybean producer. Revenues in 2022 topped $66 billion. This consists of greater than $34 billion in exports, based on the USDA’s International Agricultural Service.
“It’s a novel crop as a result of it is rather vital to future protein meals safety,” mentioned Rainey, who was featured prominently within the newest cover story of Seed World journal. But soybean makes use of are principally industrial, which means that folks eat solely a small share of its manufacturing.
“You would possibly often eat a conventional soy meals like tofu or edamame. However for essentially the most half, 95% of soybeans globally are fed to chickens and pigs and are the idea of that meals chain,” Rainey mentioned.
To keep up soybean’s burgeoning manufacturing, researchers will want a extra finessed understanding of how climate and local weather have an effect on yield in a spread of environments involving genetic variation. Breeders would then have the ability to choose soybean varieties extra strategically.
“The genetic variation is vital as a result of the obvious manner that breeders or breeding organizations within the personal sector would use the info that we produce can be in what’s referred to as genomic prediction,” Rainey defined.
Given sufficient knowledge over your entire soybean genome, genomic prediction permits breeders to create a statistical mannequin that predicts yield for 10,000 untested strains.
“However the genomic prediction fashions have to be calibrated to environments and have extra info in them than what’s at the moment in there,” Rainey mentioned. Additionally wanted is a mannequin that features biomass predictions. Such fashions are primarily based on drone imagery and genetics.
“In my lab, we work on combining that info. We’re nearly the one ones to do this throughout the general public and the personal sector in soybean,” she mentioned.
