Sixty two genotypes of sunflower have been clustered into seventeen clusters based on their genetic diversity. Among the twelve characters studied, plant height, number of chaff seeds/head, seed yield/plant and head diameter showed high contribution towards total divergence. The clusters V, XV and XVII showed superior mean performance and high inter cluster distance. Hence genotypes of these clusters namely TNAUSUF 6/8 and No. 61/7 (cluster V)j TNHAP 179 (cluster XV) and 1149–21 (cluster xvm have been selected for intermatting among themselves to produce wider segregation.
