ABSTRACT

Biological efficiency in crop production is achieved most effectively by using host resistance that will neutralize or minimize losses caused by adversities in production. Current events relative to inflation, energy conservation and minimal use of pesticides has placed host resistance in a paramount position for use in maintaining health of domestic plants. Resistance in a variety to only one or two adversities (disease, insects and stresses) is inadequate for modern agriculture. Instead, modern cultivars must have some level of resistance to known and potential adversities that may damage the crop. For this reason programs of genetic improvement which are more effective in identifying and accumulating genes having to do with host resistance to a broad range of adversities are needed. The multi-adversity resistance (MAR) program for genetic improvement of cotton is such a system. The system brings together broad spectrum resistance to diseases and insects in cotton. More importantly the system apparently is utilizing genes in cotton which have largely been bypassed by most conventional procedures used for genetic improvement (2).
