non-race-specific resistance


horizontal resistance

a situation where a large number of genes (POLYGENES) in the host plant confer a general level of resistance to a wide range of attacking organisms (pathogens or parasites). Such a system is usually able to withstand genetic changes in the attacking organism and thus produce stable production of crops. Compare RACE-SPECIFIC RESISTANCE.
