The continued expansion of the world population,increasingly inconsistent climate and shrinking agri-cultural resources present major challenges to crop breeding.Fortunately,the increasing ability to dis-cover and manipulate genes creates new opportunities to develop more productive and resilient cultivars.Many genes have been described in papers as being beneficial for yield increase.However,few of them have been translated into increased yield on farms.In contrast,commercial breeders are fac-ing gene decidophobia,i.e.,puzzled about which gene to choose for breeding among the many identified,a huge chasm between gene discovery and cultivar innovation.The purpose of this paper is to draw atten-tion to the shortfalls in current gene discovery research and to emphasise the need to align with cultivar innovation.The methodology dictates that genetic studies not only focus on gene discovery but also pay good attention to the genetic backgrounds,experimental validation in relevant environments,appropri-ate crop management,and data reusability.The close of the gaps should accelerate the application of molecular study in breeding and contribute to future global food security.
