Abstract
Resistance of sorghum to Contarinia sorghicola was evaluated at College Station, Texas, from 1980-83 and at Stillwater, Oklahoma, in 1983. Resistant entries SC0175, SC0423, MB-10 and SGIRL-MR-1 were crossed with susceptible entries Wheatland, OK94 and Caprock. The parents, F1, F2, F3 and backcross populations were visually rated for damage after natural midge infestation. The ratings of segregating populations of plants suggested that resistance was controlled by recessive genes at 2 or more loci. In crosses, SGIRL-MR-1 behaved differently from the other 3 resistance sources, and Caprock gave a higher number of susceptible plants than the other 2 susceptible parents. It appeared difficult to transfer genes for resistance to C. sorghicola into good agronomic B-lines by simple hybridization. The small glume character carried by some resistant entries appears to be a useful genetic marker
