Description Sorghum midge, Contarinia sorghicola Coq. i s the most Important
pest of grain sorghum, Sixteen gennplssm and 14 breeding lines showlng
stable resistance to midge have been i d e n t i f i e d . Progress has hen
made i n developing improved midge resistant breeding lines wlth
acceptable y i e l d and grain qualit). Sorghum variety, ICSV 197 (PM
11344) has shown high levels of midge resistance over seasons and
locations. I t s y i e l d potential i s comparable to some of the comnercial
cultivars. PI4 6751, PH 7061 and PM 8787-2 have been i d e n t i f i e d as
non-restorers. Midge resistance i s a quantatively inheri ted t r a i t
governed by both addi ti ve and nonadd i ti ve , but predominantly nonaddi ti ve
genes. Dominant genes contributed most towards midge resistance followed
by additive x additive, additive x dominance, and additive gene effects.
