Genotype × environment interactions and genetic variation reveal stable, high-yielding, and organosulfur-rich garlic cultivars adapted to tropical conditions.

ABSTRACT: Garlic is valued for its yield and sulfur-containing bioactive compounds, but the influence of genotype × environment (G × E) interactions on these traits remains poorly understood. This study evaluated seven garlic cultivars: Tawangmangu Baru (TB), Lumbu Kuning (LK), Sangga Sembalun (SS), Lumbu Putih (LP), Geol (G), Kusuma (K), and Lumbu Hijau (LH), across two agroclimatic regions in Mojokerto (cool) and Pasuruan (warm), Indonesia, during the 2022 and 2023 growing seasons. Key traits, including yield and organosulfur compounds (allicin, S-allyl cysteine [SAC], γ-glutamyl-S-allyl-L-cysteine [GSAC], alliin) were assessed. G × E interactions were analyzed using the Additive Main Effects and Multiplicative Interaction (AMMI) model. Single-nucleotide polymorphism (SNP) variation in the DELLA-l
