The construction of covariance matrices that account for the genetic relationships among individuals, using pedigree or genotype data, is integral to genetic evaluations, which are now routinely used in the field of animal breeding. The objective of the present study was to estimate the standard deviation in the proportion of the segregating genome that is shared between pairs of full-sibling cattle

Performance of tetraploid biofortified potato clones in Rwanda Crop Sci. (IF 2.763) Pub Date : 2023-04-18 Placide Rukundo, Theophile Ndacyayisenga, Elke Vandamme, Jean Claude Nshimiyimana, Mendes Thiago
The potential of biofortified crops and their critical role in Rwandan diets motivated the Ministry of Agriculture through Rwanda Agriculture and Animal Resources Development Board (RAB) to adopt a national policy of combating micronutrients’ deficiencies by developing and releasing fortified crop varieties. In this context, 37 biofortified potato (Solanum tuberosum) clones were introduced from the

Correction: Theoretical accuracy for indirect predictions based on SNP effects from single-step GBLUP Genet. Sel. Evol. (IF 5.1) Pub Date : 2023-04-17 Andre Garcia, Ignacio Aguilar, Andres Legarra, Shogo Tsuruta, Ignacy Misztal, Daniela Lourenco
Correction: Genetics Selection Evolution (2022) 54:66 https://doi.org/10.1186/s12711-022-00752-4 After publication of this work [1], we noticed that there was an error in Eqs. (14) to (19) presented on page 4 of the paper, where we refer to the term \(\mathrm{var}(\widehat{\mathbf{a}})\) as the prediction error covariance (PEC) of SNP effects which is not correct. The correct equations should be:$

Development of maize inbred lines with elevated grain methionine concentration from a high methionine population Crop Sci. (IF 2.763) Pub Date : 2023-04-17 Taylor D. Hintch, Adrienne Moran Lauter, Shelly M. Kinney, Thomas Lubberstedt, Ursula Frei, Prakasit Duangpapeng, Jode W. Edwards, Marvin Paul Scott
Methionine is a nutritionally limiting amino acid in poultry diets based on maize (Zea mays L.) grain. Synthetic dietary supplements are available but are costly and not preferred by organic poultry producers. The development of high methionine maize varieties would reduce the need for supplementation. Several approaches have been reported for achieving this goal. Here, we report a novel approach that

Seed dormancy in Asteraceae: a global vegetation zone and taxonomic/phylogenetic assessment Seed Sci. Res. (IF 1.585) Pub Date : 2023-04-17 Carol C. Baskin, Jerry M. Baskin
The Asteraceae with up to 30,000 species occurs on all continents except Antarctica and in all major vegetation zones on earth. Our primary aim was to consider cypselae dormancy-break and germination of Asteraceae in relation to ecology, vegetation zones and evolution. Cypselae are desiccation-tolerant and in various tribes, genera, species and life forms of Asteraceae are either non-dormant (ND) or

Potential of publicly available Beta vulgaris germplasm for sustainable sugarbeet improvement indicated by combining analysis of genetic diversity and historic resistance evaluation Crop Sci. (IF 2.763) Pub Date : 2023-04-15 Muhammad Massub Tehseen, Rachael Claire Poore, Karen K. Fugate, Melvin D. Bolton, Vanitharani Ramachandran, Nathan A. Wyatt, Xuehui Li, Chenggen Chu
Sugar beet (Beta vulgaris L. ssp. vulgaris Doell.) was originally selected from white fodder beet in the 1780s and was then specifically bred for sucrose production. The relatively recent inception of the crop has led to a narrow genetic base that has bottlenecked sustainable improvement. To evaluate the potential of publicly available germplasm for sugar beet improvement, genetic diversity analysis

Harvest aids did not advance maturity of non-shatter pennycress Crop Sci. (IF 2.763) Pub Date : 2023-04-15 Julija A. Cubins, Samantha Wells, Russ W. Gesch, Gregg A. Johnson, Maninder K. Walia, Ratan Chopra, M. David Marks, Rebecca D. Swenson, Katherine Frels
Reliance on summer annual crops in the Upper Midwest results in fallow land from late fall through early spring, providing opportunities to integrate winter crops, such as pennycress (Thlapsi arvense L.), onto the landscape. Pennycress agronomics have primarily been studied using unimproved wild-type lines prone to seed shatter, resulting in significant yield loss if not harvested early. However, high

Agro-morphological characterization and diversity analysis of Coffea arabica germplasm collection from INIA, Peru Crop Sci. (IF 2.763) Pub Date : 2023-04-04 Richard Paredes-Espinosa, Dina L. Gutiérrez-Reynoso, Diego Atoche-Garay, Pedro Javier Mansilla-Córdova, Yudi Abad-Romaní, Carolina Girón-Aguilar, Itala Flores-Torres, Ana Gabriela Montañez-Artica, Carlos I. Arbizu, Carlos A. Amasifuen Guerra, Jorge L. Maicelo Quintana, Carlos Poemape, Juan Carlos Guerrero-Abad
Coffee (Coffea arabica L.) plays a major role in the economy of Peru and the world. The present study aims to elucidate the agro-morphological variability of coffee genotypes maintained in the INIA´s germplasm collection. Therefore, 20 vegetative, reproductive, and phytosanitary traits of 162 coffee accessions of INIA's germplasm collection were evaluated and analyzed. Correlation results indicate
