This study presents the findings of an ex-ante impact assessment of an Australian Centre for International Agricultural Research (ACIAR)-funded project entitled ‘Improving post-rainy-season sorghum varieties to enhance their competitiveness in the farming system to meet the grain and fodder demand in India’. The ex-ante impact assessment was carried out to provide estimates of the potential economic gains that would accrue to the different economic agents along the sorghum value-chain under varying yield scenarios. Such information would be critical in planning the second phase of the project when the improved materials are disseminated to farmers. The primary aim of the ACIAR project was to maximize grain/stover yield and quality of post-rainy-season sorghum by maximizing post-anthesis (after flowering) water use and water use efficiency (WUE) to enhance grain filling. This would be achieved by developing single- and multiple-quantitative trait loci (QTL) stay-green introgression isolines, and assessing the contributions of each of these QTL to grain/fodder productivity and grain/fodder quality under normal and drought-stressed conditions. The planned outputs of this project would thus be the isolines with key stay-green QTL that have a higher drought adaptation and fodder quality, and the knowledge of traits that are related to more efficient water use. The primary target sites of the project are western Maharashtra and northern Karnataka, which represent the largest post-rainy-season-sorghum area in India. The secondary site comprises the sorghum-growing regions of Australia which are similarly water-limited. An added benefit is that the capacity of the scientists in both countries engaged in the project would be enhanced. Section 2 of this report presents a brief outline and justification of the project, and highlights its planned research outputs and potential outcomes. Section 3 outlines the methodology used in estimating the potential benefits and costs of the project, along with an explanation of the parameters used. Section 4 presents the findings of the analysis. Conclusions are presented in Section 5.
