SUMMARY
In Kharif, 2021, a comprehensive study was conducted at CCS Haryana Agricultural
University, Hisar, to determine the response of 40 sorghum genotypes against sorghum shoot fly
under field condition, replicated thrice in randomized block design. 24 sorghum genotypes exhibited
ovipositional preference (ovipositional mean 1.76eggs laid/plant with deadheart infestation of 18.95%)
while, 16 sorghum genotypes shown ovipositional preference (2.37eggs laid/plant with deadheart
25.81%) and same trend was evident at 14 days after seedling emergence indicating higher the
oviposition, higher of numbers of deadheart (%) in sorghum lines. As the glossiness of leaves (scale
1-5) declined, per cent deadheart infestation increased caused by shoot fly sand vice versa in
different sorghum genotypes. On the basis of glossiness of leaves (scale 1-5), two sorghum genotypes
fell in the range of 0.0–1.0 (deadheart 9.77%), five in a range of 1.1–2.0 (deadheart 14.75%), nine in a
range of 2.1-3.0 (deadheart 22.82%), 20 in a range of 3.1–4.0 (deadheart 23.93%) and four genotypes
fallen in a range of 4.1–5.0 (deadheart 28.70%). Sorghum genotypes (11) with closed canopy type of
plants preferred more (deadheart 23.18%) by sorghum shoot fly over genotypes (29) having open
canopy (deadheart 21.21%). Thus, traits associated with plants can be used as markers for developing
shoot fly-resistant sorghum varieties.
