520			_aThe purpose of this research is to assess the climatic sensitivity of high yielding variety ('HYV') 'green revoltuion' wheat. Improved multiple regression models were constructed for yields in India and Sonora, Mexico - the two most intensively planted regions in the world. After isolating the most important climatic predictors (which, not surprisingly, are total rainfall over the irrigation basins), the models were reduced to the pre-HYV period, and then re-run with successively more years of HYV input. This test indicated that increased adoption of the HYV package is associated with a significant increase in yield sensitivity to the
