Elite Alleles of EPE1 Identified via Genome-wide Association Studies Increase Panicle Elongation Length in Rice.

ABSTRACT: Panicle elongation length (PEL), which determines panicle exsertion, is an important outcrossing-related trait. Mining genes controlling PEL in rice (Oryza sativa L.) has great practical significance in breeding cytoplasmic male sterility (CMS) lines with increased PEL and simplified, high-efficiency seed production. Genome-wide association studies (GWAS) were performed on the PELs of 440 rice accessions in 2022 and 2023, considering 3.17 million single-nucleotide polymorphisms (SNPs) to detect the effects of different genes on PEL. A total of five quantitative trait loci (QTLs) significantly associated with PEL were detected in both years by using the general linear model (GLM) and the mixed linear model (MLM). Notably, our study identified a previously unreported QTL, qPE2.1. Three candi
