Abstract

                                Four cultivars of pearl millet, consisting of an open-pollinated variety CO. 6 and three hybrids KM UCH 4 and KM, were tested for stability and adaptation in nine different environments with in Tamil Nadu. The highest mean yield was registered by CO.6 while KM recorded the lowest mean yield. All the four cultivars were found to be generally adapted to all the environments because of the unit regression coefficients. With regard to stability as measured by coefficient of determination, KM was outstanding. The other three cultivars were similar in their stability levels
