Response of sorghum varieties to Contarinia sorghicola and Rhopalosiphum maidis at different planting dates



Response of sorghum varieties to Contarinia sorghicola and Rhopalosiphum maidis at different planting dates



Bragantia 35(2): 365-374



Four early and four late varieties, with two resistant and two susceptible in each group, were tested after planting at four dates between 3 November 1967 and 2 Jan 1968. AF28, AF37 and AF117, with open panicles, were more resistant to Rh. maidis than the varieties with compact panicles. AF28 and AF117 were also resistant to C. sorghicola. The genetic factors controlling resistance to the two pests were independent.
