Production innovations to enhance sweetpotato as a food security crop in northern Ghana Crop Sci. (IF 2.3) Pub Date : 2024-03-11 Issah Sugri, Daniel Akansake, Issah A. Abukari, Jan W. Low, Putri E. Abidin, Eric K. Dery, Kwabena Acheremu, Joseph Adjebeng‐Danquah, John K. Bidzakin, Mutari Abubakari, Salim Lamini, Edward E. Carey
Sweetpotato (Ipomoea batatas (L) Lam) is prioritized among crops that enhance food security and reduce malnutrition in Ghana. The production is expanding faster than other food crops owing to its superior nutrient composition. This study evaluates integrated approaches to increase on‐farm productivity, income, and utilization of sweetpotato. The first part evaluated the agronomic yield performance

Genomewide marker estimates of the level of dominance in maize heterosis Crop Sci. (IF 2.3) Pub Date : 2024-03-11 Patrick K. Sweet, Robenzon E. Lorenzana, Rex Bernardo
Heterosis is the superiority of an F1 hybrid over its parents, and overdominance and dominance are the two main hypotheses for the genetic basis of heterosis. Our objectives were to determine if genomewide marker effects accurately reflect the level of dominance at quantitative trait loci (QTL) and assess the distribution of per‐marker estimates of the level of dominance in maize (Zea mays L.). We

Confidence intervals for validation statistics with data truncation in genomic prediction Genet. Sel. Evol. (IF 4.1) Pub Date : 2024-03-08 Matias Bermann, Andres Legarra, Alejandra Alvarez Munera, Ignacy Misztal, Daniela Lourenco
Validation by data truncation is a common practice in genetic evaluations because of the interest in predicting the genetic merit of a set of young selection candidates. Two of the most used validation methods in genetic evaluations use a single data partition: predictivity or predictive ability (correlation between pre-adjusted phenotypes and estimated breeding values (EBV) divided by the square root

The scholarship of honorifics Crop Sci. (IF 2.3) Pub Date : 2024-03-04 John M. Davis, J. Scott Angle, Robert J. Ferl, Robert A. Gilbert, Amy M. Grunden, Tim G. Rials, Scott A. Senseman, Gary A. Thompson, Michael D. Toews
Nomination is a scholarly activity, not unlike writing a manuscript or grant proposal. Nomination is elevated by recognizing both recipients and nominators. A nominagraph adds a dimension to the pairwise listing of recipients and nominators on ASA/CSSA/SSSA directories.

GWABLUP: genome-wide association assisted best linear unbiased prediction of genetic values Genet. Sel. Evol. (IF 4.1) Pub Date : 2024-03-01 Theo Meuwissen, Leiv Sigbjorn Eikje, Arne B. Gjuvsland
Since the very beginning of genomic selection, researchers investigated methods that improved upon SNP-BLUP (single nucleotide polymorphism best linear unbiased prediction). SNP-BLUP gives equal weight to all SNPs, whereas it is expected that many SNPs are not near causal variants and thus do not have substantial effects. A recent approach to remedy this is to use genome-wide association study (GWAS)

Searching for homozygous haplotype deficiency in Manech Tête Rousse dairy sheep revealed a nonsense variant in the MMUT gene affecting newborn lamb viability Genet. Sel. Evol. (IF 4.1) Pub Date : 2024-02-29 Maxime Ben Braiek, Carole Moreno-Romieux, Céline André, Jean-Michel Astruc, Philippe Bardou, Arnaud Bordes, Frédéric Debat, Francis Fidelle, Itsasne Granado-Tajada, Chris Hozé, Florence Plisson-Petit, François Rivemale, Julien Sarry, Némuel Tadi, Florent Woloszyn, Stéphane Fabre
Recessive deleterious variants are known to segregate in livestock populations, as in humans, and some may be lethal in the homozygous state. We used phased 50 k single nucleotide polymorphism (SNP) genotypes and pedigree data to scan the genome of 6845 Manech Tête Rousse dairy sheep to search for deficiency in homozygous haplotypes (DHH). Five Manech Tête Rousse deficient homozygous haplotypes (MTRDHH1
