The studies on seasonal variation in sorghum (Somalia
germplasm) resistance to shoot fly Atherigona varia soccata
Rondani were conducted in four experimental sowings in three
seasons viz. late postrainy season 1990-9 1, early rainy
1991, and early postrainy 1991-92 at ICRISAT Center.
Investigations included evaluation for resistance of the
entries to the shoot fly over seasons for less oviposition,
less damage resulting in fewer dead hearts and
tolerance/recovery resistance.
In view of seasonal variation, entries were assessed in
relation to various environmental parameters namely
temperature, humidity and rainfall and their influence on
varietal ~esistance was monitored
