Abstract

Recent criticisms of the 'green revolution' wheats concern the effects of their popularity on crop diversity and the consequences for productivity and conservation. We use a Just-Pope production function to test the relationship of genetic resource and diversity variables to mean and variance of wheat yields in the Punjab of Pakistan. In irrigated areas, greater area concentration among varieties is associated with higher mean yields. In rainfed districts, genealogical variables are associated positively with mean yield and negative with yield variance. Further research is needed to overcome data limitations, capture biological relationships more accurately, and specify a fuller decision-making model.
