The Phenotypic and Genotypic Eras of Crop Improvement
Trait-based, or phenotypic, selection has been the primary means by which plants have been genetically adapted to the needs of human societies and the demands of nature. Progress from phenotypic selection has varied widely among plant species and ecogeographic regions. Nascent direct assessments and manipulation of plant genomes constitute a novel approach to crop improvement. Knowledge of the genotype is assumed by many to be an important source of additional progress. While some degree of such progress is inevitable from that source, and some progress has been achieved, the initial assessments of whole genomes have revealed unexpected features and complexity which may hinder our ability to directly exploit the deluge of information emanating from genomics. The future of successful plant breeding and crop improvement will consist of a judicious balance and integration of phenotypic and genotypic selection.
