This study investigates the genotype-by-environment interaction (GEI) effects and identifies stable, high-yielding confectionery-quality groundnut genotypes using AMMI and GGE biplot models. The research was conducted in two locations, Junagadh (Gujarat) and Bikaner (Rajasthan), India, with 43 confectionery groundnut genotypes. Key traits measured included pod yield per plant (PYP), number of pods per plant (NPP), hundred kernel weight (HKW), and shelling percentage (SP). The results from the Interaction Principal Component Analysis (IPCA) showed that HKW contributed 76.68% and 18.95% to the Global Environmental Index (GEI) through IPCA1 and IPCA2, respectively. Similarly, NPP contributed 87.52% and 8.65%, PYP contributed 95.87% and 2.1%, and SP contributed 77.4% and 16.22% to the GEI through IPCA1 and IPCA2. Genotypes PBS 29233 and PBS 29230 exhibited superior performance and stability in terms of pod yield, hundred kernel weight, number of pods per plant, and shelling percentage across various sites. These genotypes are potential candidates for developing confectionery-grade groundnuts with larger seeds to meet the growing demand for export. The study also highlights the importance of considering both mean performance and stability when selecting genotypes for specific environments.This study investigates the genotype-by-environment interaction (GEI) effects and identifies stable, high-yielding confectionery-quality groundnut genotypes using AMMI and GGE biplot models.
