Genetic variability and associations among yield and yield‐related traits in Ethiopian linseed (Linum usitatissimum L.) landraces

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Linseed (Linum usitatissimum L.) is a key oilseed crop in Ethiopia's central highlands. However, its productivity is constrained by the limited availability of high‐yielding varieties, highlighting the importance of investigating genetic variability and trait associations among local landraces.

A Functional Joint Model for Survival and Multivariate Sparse Functional Data in Multi‐Cohort Alzheimer's Disease Study

Statistics in Medicine, Volume 45, Issue 3-5, February 2026.
ABSTRACT We develop an integrative joint model for multivariate sparse functional and survival data to analyze Alzheimer's disease (AD) across multiple studies. To address missing‐by‐design outcomes in multi‐cohort studies, our approach extends the multivariate functional mixed model (MFMM), which integrates longitudinal outcomes to extract shared ...

A Functional Approach to Testing Overall Effect of Interaction Between DNA Methylation and SNPs

Statistics in Medicine, Volume 45, Issue 1-2, January 2026.
ABSTRACT We introduce a test for the overall effect of interaction between DNA methylation and a set of single nucleotide polymorphisms on a quantitative phenotype. The developed inference procedure is based on a functional approach that extend existing regression models in functional data analysis.

Genetic Heterogeneity of Residual Variance for Foot Score Traits in American Angus Cattle

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 68-78, January 2026.
ABSTRACT Foot conformation is one of the main breeding goals in recent beef cattle breeding programs because it directly affects productivity, economic losses, animal welfare and longevity. Genetic heterogeneity of residual variance can be used to improve production uniformity in animal breeding programs because recent studies have shown that residual ...
