Modeling the impact of resource allocation decisions on genomic prediction using maize multi‐environment data Crop Sci. (IF 2.0) Pub Date : 2024-07-24 Dylan L. Schoemaker, Dayane Cristina Lima, Natalia de Leon, Shawn M. Kaeppler
In a hybrid maize (Zea mays L.) breeding program that utilizes genomic selection, resource allocation used in phenotypic data acquisition must be balanced between population size, number of environments, and the number of testers used for generating hybrids. Plant breeders evaluate newly developed inbred lines using multi‐environment trials to account for genotype‐by‐environment interaction effects

Transcriptome analysis of the molecular basis of 11‐eicosenoic acid‐mediated salt stress tolerance in rice Crop Sci. (IF 2.0) Pub Date : 2024-07-22 Shiqing Dong, Juan He, Yuming Luo, Xiaokang Han
Salt stress is one of the major abiotic factors severely hampering rice production. Fatty acids play a crucial role in plants response to such stress. Previous studies have demonstrated the potential of unsaturated fatty acid (11‐eicosenoic acid [EA]) to enhance salt tolerance in rice, but the molecular mechanism remains unclear. Our study indicates that the exogenous application of EA could alleviate

Seeding rate recommendations for wheat (Triticum aestivum L.) are often 150–450 seeds m−2. However, we hypothesize that wheat grown with high resource availability (i.e., fertility and moisture) can maximize yield under considerably lower rates. Our objectives were to explore winter wheat response to low populations under high resource availability using yield-contest fields as a case study. A factorial

Progress toward impact at scale of orange-fleshed sweetpotato in Ghana Crop Sci. (IF 2.0) Pub Date : 2024-05-24 Putri E. Abidin, Isaac K. Dorgbetor, Kwadwo Adofo, Kwabena Acheremu, Joseph Adjebeng-Danquah, Isaac Conduah, Marjolein Ebregt, Souleimane A. Adekambi, Edward E. Carey
Sweetpotato (Ipomoea batatas L.) was known as a minor root crop in Ghana. Starting in 2010, the International Potato Center (CIP) and multiple partners implemented orange-fleshed sweetpotato (OFSP) projects to reposition this crop in Ghana. CIP-led projects from 2010 to 2021 were identified as Research for Development Initiative projects. These projects consisted of (i) new variety development and

Substitution mapping of yield-related traits utilizing three Cybonnet rice × wild introgression libraries Crop Sci. (IF 2.0) Pub Date : 2024-05-24 Georgia C. Eizenga, Jeremy D. Edwards, Aaron K. Jackson, Trevis D. Huggins
Improving rice (Oryza sativa L.) yields is a major objective of breeding programs worldwide. The Oryza rufipogon species complex (ORSC), which includes the rice ancestral species O. rufipogon Griff. and O. nivara S. D. Sharma & Shastry, is an underutilized resource. Using three phenotypically and genotypically diverse ORSC accessions identified as OrA, OrB, and OrC, three Cybonnet × ORSC chromosome

An investigation of the impact of imbalance on the analysis of the US crop variety evaluation program data Crop Sci. (IF 2.0) Pub Date : 2024-05-24 Zhou Fang, Dewayne D. Deng, Johnie N. Jenkins, Qian M. Zhou
Multi-environment trial data from many crop variety evaluation programs are imbalanced because only a subset of varieties is selected for the following year, which leads to missing variety by year. Inspired by the US National Cotton Variety Test trial, we conducted new simulation studies to investigate selection processes that differ from the existing literature. The followings are our four main contributions

Combined selection for productivity, adaptability, and stability in corn genotypes for baby corn production Crop Sci. (IF 2.0) Pub Date : 2024-05-24 Maxwel Rodrigues Nascimento, Gérsia Gonçalves de Melo, Luciano Antonio de Oliveira, Alessandra Querino da Silva, Carlos Pereira da Silva, Paulo Ricardo dos Santos, Rogério Figueiredo Daher
Baby corn is the name given to the female inflorescence of corn (Zea mays L.) before fertilization, being harvested in 2–3 days after the issuance of the styles-stigmata. Currently, in Brazil, there is no specific corn cultivar for baby corn production, which leads to the use of popcorn and sweet corn cultivars because they are more accepted in the food industry. Therefore, the objective of this work

The Grain Number Increase 1 alleles GNI-A1-105Y and -105K increase grain number in spring wheat Crop Sci. (IF 2.0) Pub Date : 2024-05-22 C. O. Hale, B. J. Tillett, J. M. Martin, A. C. Hogg, J. P. Cook, M. J. Giroux
Wheat (Triticum aestivum L.) has inflorescences made up of multiple spikelets arranged along a central rachis, with each spikelet producing between one and four grains. The Grain Number Increase 1 (GNI-A1) gene wheat directly influences grain number per spikelet and grain size. Three naturally occurring alleles have been described previously: GNI-A1-105N, 105Y, and 105K. This project's goal was to

Improving selection decisions with mating information by accounting for Mendelian sampling variances looking two generations ahead Genet. Sel. Evol. (IF 3.6) Pub Date : 2024-05-21 Tobias A. M. Niehoff, Jan ten Napel, Piter Bijma, Torsten Pook, Yvonne C. J. Wientjes, Bernadett Hegedűs, Mario P. L. Calus
Breeding programs are judged by the genetic level of animals that are used to disseminate genetic progress. These animals are typically the best ones of the population. To maximise the genetic level of very good animals in the next generation, parents that are more likely to produce top performing offspring need to be selected. The ability of individuals to produce high-performing progeny differs because

Integration of selective sweeps across the sheep genome: understanding the relationship between production and adaptation traits Genet. Sel. Evol. (IF 3.6) Pub Date : 2024-05-21 Pablo A. S. Fonseca, Aroa Suárez-Vega, Juan J. Arranz, Beatriz Gutiérrez-Gil
Livestock populations are under constant selective pressure for higher productivity levels for different selective purposes. This pressure results in the selection of animals with unique adaptive and production traits. The study of genomic regions associated with these unique characteristics has the potential to improve biological knowledge regarding the adaptive process and how it is connected to

A recurrent de novo missense mutation in COL1A1 causes osteogenesis imperfecta type II and preterm delivery in Normande cattle Genet. Sel. Evol. (IF 3.6) Pub Date : 2024-05-21 Julien Corbeau, Cécile Grohs, Jeanlin Jourdain, Mekki Boussaha, Florian Besnard, Anne Barbat, Vincent Plassard, Julie Rivière, Christophe Hamelin, Jeremy Mortier, Didier Boichard, Raphaël Guatteo, Aurélien Capitan
Nine male and eight female calves born to a Normande artificial insemination bull named “Ly” were referred to the French National Observatory of Bovine Abnormalities for multiple fractures, shortened gestation, and stillbirth or perinatal mortality. Using Illumina BovineSNP50 array genotypes from affected calves and 84 half-sib controls, the associated locus was mapped to a 6.5-Mb interval on chromosome
