Abstract

INTRODUCTION Yield Gains can be estimated by comparing On-Farm yields vs. Potential yield (a.k.a., realized yield) or measured in common trials. The difference between On-Farm yield and Potential yield is known as the Yield Gap. Plant breeders primarily focus on increasing Potential yield while also attempting to optimize the interaction between genotype, environment, and agronomic practices to increase On-Farm yield and reduce the Yield Gap. In recent years, scientists in developing countries and the U.S. have made major advances in dry bean disease resistance, stress tolerance, and increased yield (Kelly, 2004). Agronomic and biotechnological tools have contributed to these achievements. The objective is to estimate Yield Gains in dry beans in the U.S.
