Adoption is defined as the proportion of total area of a given coarse cereal planted to modern cultivars. Agroclimatic and soil differences are more important than disparities in infrastructure in explaining the variation across regions in estimated adoption ceilings. Qualitatively different modern cultivars from those now released are necessary to change regional adoption behavior. The results support an agricultural research strategy that gives higher priority to more regionally oriented breeding and testing programs in preference to the past emphasis on wide adaptation publisher: Blackwell Publishing date: 1990 type: Article type: PeerReviewed format: application/pdf language: en identifier: http://oar.icrisat.org/7689/1/AJAE_72_3_653-663_1990.pdf identifier: Jansen, H G P and Walker, T S and Barker, R (1990) Adoption Ceilings and Modern Coarse Cereal Cultivars in India.
