Dissecting genetic architecture of flowering and maturity traits in soybean using GWAS in Indian environment.

ABSTRACT:

Background

Soybean (Glycine max [L.] Merril) is a photoperiod-sensitive crop, with traits like days to flowering, days to maturity playing crucial roles in its adaptability and yield. These traits are regulated by genetic networks controlling flowering time and environmental adaptation, making their genetic basis as an essential knowledge for breeders aiming to improve yield and adaptability. In this study, a Genome-Wide Association Study (GWAS) was conducted for Days to flowering (DTF) and days to maturity (DTM) by using FarmCPU, BLINK and MLM models on 254 diverse soybean genotypes over four consecutive years (2019-2022) to dissect genetic architecture for flowering and maturity traits in an Indian Environment.

Results

In this study, GWAS identified 20 significant loci for
