The present research aimed to identify adaptable Brassica cultivars addressing climate restoration approaches under different agroforestry systems. Significant differences were observed among ten Indian mustard genotypes for all the studied traits under all environments, i.e., Open field, Poplar and Eucalyptus tree system. The genotype × environment (G×E) interaction was studied using the Eberhart and Russell stability model. Based on the stability parameters, genotypes were categorized as stable or unstable for all three environments.

Observations were recorded for yield and related traits viz., number of silique in the main raceme (NSM), the number of seeds per silique (SS), 1000 grain weight (GW) and grain yield. Stability analysis revealed that mustard variety CS56 had been found stable for seed yield in the Open field. RGN 73 had a high mean value and consistent performance in all environments for NSM. NDRE 4 had shown uniform performance for seeds/siliqua in all environments whereas RH7409 had recorded high mean performance and non-significant S2di for 1000 GW. However, the low value of bi <1 suggested its suitability under Eucalyptus.
