... The QPM varieties developed by Centro Internacional de Mejoramiento de Maiz y Trigo (CIMMYT) have performed as well as common maize in trials and seem to have good adaptability.

... For those who remember the enthusiasm for opaque-2 maize in the 1970s, QPM suffers a "credibility gap." Researchers could be hesitant to undertake QPM studies because of the lingering memories of the earlier form that did not live up to its billing. LACK OF DISTINGUISHING FEATURES The fact that QPM is now indistinguishable in appearance from common commercial maize is also a potential limitation.

... QPM has outstanding promise where maize is a preferred item in the diet, but unforeseen factors may arise. People who have used maize all their lives may recognize subtle differences and may suspiciously reject QPM as "alien." SPECIAL HANDLING QPM seed plots must be isolated from the pollen of other maize types.

... A beginning has already been made; CIMMYT expects to test hybrids at farm level within a few years. Moreover, researchers at Texas A & M and other universities also have QPM hybrids in preparation.3 Although hybrids are a way of stabilizing the purity of the QPM traits, they have to be produced centrally, farmers must buy new seed each year, and hybrid seeds cost appreciably more than those of traditional, open-pollinated varieties.

... Its eradication will thus require the inputs of preventive medicine and medical care. In addition, any nutrition-improvement program should be a component of other interventions such as those that modify living conditions, improve water supplies and food storage, and increase income.
