Varietal Resistance of Sorghum to the Sorghum-Shoot-Fly (Atherigona varia var. soccata)1
- A. Blum2
Five sorghum lines from Indian germ plasm and two susceptible varieties (Tx7078 and RS-610 hybrid) were evaluated for resistance to the sorghum-shoot-fly (Ath. erlgona varia). The lines were tested under both natural and artificial infestation.
Three selections possessed a satisfactory rate of resistance, controlled by three mechanisms: a) nonprelerence for oviposition, b) avoiding larva penetration through the leaf sheaths, and c) resistance of tillers formed after the growing apex destruction.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
