“…Chr1_53838421 was in a gene annotated as transcription factor C3H family related. C3H are specific transcriptional factors with a typical motif with three cysteine residues and one histidine residue which regulate gene expression during plant growth, developmental process and environmental responses (Li and Thomas 1998;Liu et al 2020) In M. sativa 228 C3H TFs has been predicted (Nemchinov et al 2021) and the marker associated with this gene could be linked to alfalfa maturity. Marker Chr5_73969365 was in a gene coding for RNA binding protein (RBP) with GIP1_N and DUF1296 domains.…”

Yield is one of the most important agronomic traits in alfalfa breeding; however, this is a complex trait affected by genetic and environmental factors. In this study, we used multi-environment trials to test yield-related traits in a diverse panel composed of 200 alfalfa accessions and varieties. Phenotypic data of maturity (MSC), dry matter, plant height (PH), yield (Yi), and fall dormancy (FD) were collected in three locations: Idaho, Oregon, and Washington from 2018 to 2020. Single-trial and stagewise analyses within each environment were used to obtain estimated means by genotype by trait by environment. Genome-wide association studies identified a total of 84 nonredundant markers associated with the traits analyzed. Of those, 55 markers were located at 44 different loci. Ten significant SNPs at the same locus were associated with FD and they were linked to a gene annotated as a nuclear fusion defective 4-like (NFD4) protein. SNPs linked to transcription factors such as Cysteine3Histidine (C3H), Hap3/NF-YB family, and serine/threonine-protein phosphatase 7 proteins were associated with MSC, PH, and Yi, respectively. Our results provide insight into the genetic factors that influence alfalfa maturity, yield, and dormancy, which is helpful to speed up the genetic gain of alfalfa yield improvement.
