The paper attempts an analysis of the present status of improvement of varieties and hybrids of sorghum in India during the kharif season. Improved varieties like SPV-462 and SPV-475 are superior to the hybrid CSH-1 for yield as well as stability of performance and approach the commercial hybrid CSH-5. This is significant. The improved varieties are less sensitive tp years and more sensitive to locations whereas the hybrids are less sensitive to both years and locations as revealed by the interactions. The commercial hybrids are yet to show significant advance over CSH-9 in yield. The trial differentiation index as developed by Fasoulas (19S3) is a useful tool for evaluating test locations in coordinated crop improvement programmes. Based on the results. guidelines for future improvement of hybrids and varieties of sorghum during kharif in India have been furnished.
