摘　　要：This article represents the perspective of one retired,academic forage breeder and cultivar developer after 50 years of working experience.Developing cultivars that help farmers within pastoral agriculture is the main goal,a system where livestock is the consumer.International Grassland Congress proceedings,as well as the general literature,are historical guides for the state of forage breeding.Efficiency was achieved through technologies;better equipment for planting and harvesting;and advances in computer computation and communication.Biotechnology achievements were fitful and continue to evolve.Cultivar performance mean-reversion,cost to the program,and what the farmer seed buyer was willing to pay are important considerations for applying any technology,especially biotechnologies.Biotech promises were too optimistic.This was due,in part,to a lack of understanding that traditional phenotypic/genotypic field selection programs operate in a complex way with multiple species and several traits screened simultaneously at a modest cost.The majority of current forage cultivars are from field-based selection.Industry participation at scientific conferences declined over time,with less sharing of information the result.Cultivar developers will continue using basic field selection methods but should explore applying any technology;just be clever on when,how,and with whom to use them.Practical advice and experiences are also presented and discussed.
