Description A technique was developed in Andhra Pradesh, India, in which sorghum entries were subjected to an array of pest combinations to identify and separate genotypes with resistance to one or more insects. Using this technique, 220 resistance sources and breeding lines were evaluated for multiple insect resistance. Less than 10% of Atherigona soccata resistance sources had acceptable resistance (8. Similarly, all C. sorghicola resistant sources were highly susceptible to A. soccata but less so to Chilo partellus. IS 22464 was the best Contarinia sorghicola-resistant line with a score of 3 for Chilo partellus resistance. Advanced breeding lines showed a wider range of resistance to these 3 species, with a higher frequency for resistance to C. partellus. PS 28060-3 and PM 14388-1 were the most promising breeding lines.
