Popis:	An experiment with sixteen sorghum genotypes including two checks was conducted to evaluate their reaction against shoot fly at Akola, during kharif 2016–17. Observations were made on the eggs, deadhearts, seedling vigour, leaf glossiness, trichome density, chlorophyll content and Bricks index. The results revealed that the seedling leaf glossiness score (SLGS) of 1.67 to 4.67 and these were significantly positively corelated with oviposition and deadhearts. Seedling vigour score (SVS) also was observed with a positive significant association with eggs and deadhearts on 14th and 28th days after emergence. The trichomes on abaxial (lower) surface was observed to be maximum with the resistant check IS-18551, and this showed a significant negative association with oviposition and deadhearts. Chlorophyll index had highly significant positive impact on the oviposition and deadhearts. Low Bricks indices were observed in the resistant lines.
