Abstract Aphanomyces root rot (ARR) is a devastating disease in field pea ( Pisum sativum L.) that can cause up to 100% crop failure. Assessment of ARR resistance be rigorous, costly, time‐demanding activity relatively low‐throughput and prone human errors. These limits the ability effectively efficiently phenotype symptoms arising from infection which remains perennial bottleneck successful evaluation incorporation into new cultivars. In this study, we developed greenhouse‐based...
Phenotypic evaluation and efficient utilization of germplasm collections can be time-intensive, laborious, expensive. However, with the plummeting costs next-generation sequencing addition genomic selection to plant breeder's toolbox, we now more efficiently tap genetic diversity within large collections. In this study, applied evaluated prediction's potential a set 482 pea (Pisum sativum L.) accessions-genotyped 30,600 single nucleotide polymorphic (SNP) markers phenotyped for seed yield...
Abstract Multi‐trait genomic selection (MT‐GS) has the potential to improve predictive ability by maximizing use of information across related genotypes and genetically correlated traits. In this study, we extended sparse phenotyping method into MT‐GS framework split testing entries maximize borrowing predict missing phenotypes for targeted traits without additional expenditure. Using 300 advanced breeding lines from North Dakota State University (NDSU) pulse program ∼200 USDA accessions...
Abstract Seed traits, such as seed color and size, directly impact quality, affecting the marketability value of dry peas [1]. Assessing quality is integral to a plant breeding programs ensure optimal standards. This research introduced phenotyping tool assess traits specifically tailored for pulse crops, which integrates image processing with cutting-edge deep learning models. The proposed method designed automation, seamlessly sequence images while minimizing human intervention. pipeline...
Abstract Phenotypic selection of complex traits such as seed yield and protein in the preliminary trial (PYT) is often constrained by limited availability, resulting trials with few environments minimal to no replications. Multi‐trait multi‐environment enabled genomic prediction (MTME‐GP) offers a valuable alternative predict missing phenotypes candidates for multiple diverse environments. In this study, we assessed efficiency MTME‐GP improving field pea, top two breeding targets but highly...
The discovery of the opaque2 (o2) mutation and o2 modifier genes in maize (Zea mays L.) has resulted development Quality Protein Maize (QPM) lines with increased lysine tryptophan content.

Abstract ‘ND Dawn’ (Reg. no. CV‐30, PI 694866), a semi‐dwarf, semi‐leafless, large‐seeded yellow field pea ( Pisum sativum L.) cultivar, was developed by the pulse crops breeding program at North Dakota State University and approved for release Agricultural Experiment Station. ND Dawn, first cultivar from program, bulk‐pedigree method. Based on 18 environments (location‐years) of yield trials across Dakota, Dawn had similar seed (2,843 kg ha −1 ) with commercial cultivars ‘AC Agassiz’ (2,875...
ABSTRACT Phenotypic selection in preliminary yield trials (PYT) is challenged by limited seeds, resulting with few replications and environments. The emergence of multi-trait multi-environment enabled genomic prediction (MTME-GP) offers opportunity for enhancing accuracy genetic gain across multiple traits diverse Using a set 300 advanced breeding lines the North Dakota State University (NDSU) pulse crop program, we assessed efficiency MTME-GP model improving seed protein content field peas...
Abstract Background Effective population size ( N e ) is a pivotal parameter in genetics as it can provide information on the rate of inbreeding and contemporary status genetic diversity breeding populations. The with smaller lead to faster inbreeding, little potential for gain making selections ineffective. importance has become increasingly recognized plant breeding, which help breeders monitor enhance variability or redesign their selection protocols. Here, we present first estimates...

Abstract The superiority of multi-trait genomic selection (MT-GS) over univariate (UNI-GS) can be improved by redesigning the phenotyping strategy. In this study, we used about 300 advanced breeding lines from North Dakota State University (NDSU) pulse program and 200 USDA accessions evaluated for ten nutritional traits to assess efficiency sparse testing in MT-GS. Our results showed that using MT-GS consistently outperformed UNI-GS when compared partially balanced This strategy further...
