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)

The modeling of genotype × environment interactions (GEI) is important to understand how new crops perform in different environments and management systems. Naked barley (Hordeum vulgare L.) is a type of barley where the hull threshes freely from the grain and can be used for multiple end uses, including food, malt, and animal feed. We examined the performance of a winter naked barley trial grown in

Population size is not a reliable indicator of seed germination Seed Sci. Res. (IF 2.1) Pub Date : 2024-02-05 Jerry M. Baskin, Carol C. Baskin
Small isolated plant populations are one of the consequences of fragmentation of natural habitats by humans. We asked what effect does the creation of smaller populations from larger ones has on the plant fitness-related trait seed germination. Using information on 119 species (142 species entries) in 50 families, we found that seeds in only 35.2% of the species entries from larger populations germinated

Inbreeding depression is associated with recent homozygous-by-descent segments in Belgian Blue beef cattle Genet. Sel. Evol. (IF 4.1) Pub Date : 2024-01-31 Maulana Mughitz Naji, José Luis Gualdrón Duarte, Natalia Soledad Forneris, Tom Druet
Cattle populations harbor generally high inbreeding levels that can lead to inbreeding depression (ID). Here, we study ID with different estimators of the inbreeding coefficient F, evaluate their sensitivity to used allele frequencies (founder versus sample allele frequencies), and compare effects from recent and ancient inbreeding. We used data from 14,205 Belgian Blue beef cattle genotyped cows that

Pathogenicity of Puccinia striiformis f. sp. tritici and quantitative traits on bread wheat landraces in Ethiopia Crop Sci. (IF 2.3) Pub Date : 2024-02-01 Damene Dawana, Birtukan Dessie, Mesfin Kebede, Daniel Shimelash
Bread wheat (Triticum aestivum L.) is severely affected by stripe rust caused by Puccinia striiformis Westend. f. sp. tritici (Pst). This study was conducted to investigate pathogenicity of Pst isolates to bread wheat landraces grown in Ethiopia, establish stripe rust yield loss models and estimate variability in bread wheat quantitative traits. A greenhouse pot experiment was setup to assess seedling

Dry storage alters intraspecific variation in phenotypic traits at early life stages: evidence from a dominant alpine meadow species Seed Sci. Res. (IF 2.1) Pub Date : 2024-02-01 Dali Chen, Haiying Yuan, Jinglong Bao, Xiaohua Zhao, Xiuzhen Fu, Xiaowen Hu
The intraspecific variations of phenotypic traits in the early life stages, such as seed germination and seedling establishment, are important components affecting species adaptation and differentiation. As one of the most common ways in which seeds are maintained, dry storage usually affects these traits, by either increasing or decreasing variation among populations. However, little is known about

Indices for measuring ratooning ability of sugarcane varieties Crop Sci. (IF 2.3) Pub Date : 2024-01-31 Njabulo Eugene Dlamini, Angelinus C. Franke, Marvellous Zhou
The primary objective of sugarcane (Saccharum spp.) variety testing programs is to identify cultivars that have high cane yields and good ratooning ability (RA). The purpose of this study was to evaluate the usefulness of six RA indices to estimate RA among sugarcane varieties and to identify an index well suited to predict RA in long-term ratoon crop cycles. The six indices were as follows: ratoon

Increasing the seed production efficiency of autumn potato with plant growth regulators Crop Sci. (IF 2.3) Pub Date : 2024-01-31 Amanpreet Singh, C S Aulakh, A S Sidhu
Higher productivity of seed-size tubers is a significant issue in seed potato (Solanum tuberosum) production systems. Punjab, in northwest India, is the hub of seed potato production and supplies 60% seed requirement of the country. However, to improve the productivity of seed-size (3.5–4.5 cm) tubers, research trials were run at Ludhiana for 2 years (autumn 2019 and 2020) to examine the effectiveness
