Premise of the study: Access to improved crop cultivars is the foundation for successful agriculture. New cultivars must have improved yields that are determined by quantitative and qualitative traits. Genotype-by-environment interactions (GEI) occur for quantitative traits such as reproductive fitness, longevity, height, weight, yield, and diseas...

Premise of the Study: In crop breeding programs, breeders use yield performance in optimal and stressful environments as key indicator for screening the most tolerant genotypes. Over four decades, several yield-based indices have been suggested for evaluating stress tolerance in crops. Despite the well-established use of these indices in agronomy a...
