Abstract

The experiments were laid out in post rainy seasons of 2001–02 and 2002–03 by taking up sowings in October, following randomized block design with three replications. Twenty sorghum parental lines along with a resistant and susceptible check were evaluated for their resistance shoot fly and aphid. The results revealed that, the lines 104A, 104B, RR 9817, RR 9818, RS 585 and RS 653 were found to be resistant to shoot fly by recording 18.7, 17.0, 14.9, 16.9, 13.4 and 16.2 per cent deadhearts, respectively. The parental lines viz., AKR 150, C 43, R 354, RS 29 and Indore 12 were categorized as resistant to aphids which scored less than 2 grade.
