abstract: Sorghum shoot fly, Atherigona soccata is an important pest of sorghum,
and host plant resistance is one of the important components for minimizing
the losses due to this pest. Therefore, we evaluated a diverse
array of sorghum genotypes to identify physico-chemical characteristics
conferring resistance to A. soccata. Susceptibility to shoot fly was associated
with high amounts of soluble sugars, fats, leaf surface wetness and
seedling vigour; while leaf glossiness, plumule and leaf sheath pigmentation,
trichome density and high tannin, Mg and Zn showed resistance to
shoot fly. Stepwise regression indicated that Mg, Zn, soluble sugars, tannins,
fats, leaf glossiness, leaf sheath and plumule pigmentation and trichome
density explained 99.8% of the variation in shoot fly damage.
Path coefficient analysis suggested that leaf glossiness, trichome density,
Mg and fat content and plant plumule pigmentation can be used as
markers traits to select for shoot fly resistance in sorghum
