Última Wheat Diversity and Productivity in Indian Punjab After the Green Revolution AgEcon Smale, Melinda; Singh, Joginder; Di Falco, Salvatore; Zambrano, Patricia. The Punjab of India is an historical source of key wheat genetic resources in national and global plant breeding, and a focus of concerns about the abandonment of local varieties during the Green Revolution. Much of the wheat area in Punjab was already planted with earlier products of modern plant breeding programs when the Green Revolution began. These cultivars were more genetically similar and less productive than the semi-dwarf wheat varieties that succeeded them. We define, summarize and test indices of variety change and genetic diversity for the modern wheat varieties released and grown in Indian Punjab during the post-Green Revolution period. The first is the area-weighted average of varieties grown, which measures the rate of variety change,...
