The current study was conducted to examine the correlation coefficients among shoot fly resistance parameters in total 12 sorghum genotypes including 04 F2 populations along with 06 parents and 02 checks in Rabi 2022-2023 at the Experimental Farm of Sorghum Research Station, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani (Maharashtra). Three replications of a randomized block design were used to conduct the current experiment. At the genotypic and phenotypic levels, the characters leaf glossiness (non-glossy), seedling vigour (non-vigorous), leaf angle and dead heart percent at 14 DAE were significant and positively correlated with shoot fly dead heart percent at 28 DAE. Whereas, trichome density (adaxial and abaxial) and plant height had recorded negative but significant association with dead heart percent at 28 DAE at both levels. While, 100 seed weight had recorded significant but positive correlation with dead heart percentage at phenotypic level only.
