Gene complementarity among various sources of resistance to greenbug biotype E was assessed. Analysis of the F2 generation of crosses between susceptible and resistant parents (mating 1) and among sources of resistance (mating 2) suggested that resistance in sorghum to greenbug biotype E was comp...

Electronic insect-feeding monitors are increasingly being used to study the feeding behavior of piercing-sucking insects in relation to host resistance and biotypes. The original AC design has been modified several times to simplify and expand the signal generator and signal processor. We report ...

For more than 30 years, the international community has been assisting Ethiopia in recovering from recurring disasters. A continual need for emergency agricultural assistance as a response to droughts, conflict snd famine has led many to question the effectiveness and sustainability of the curren...
Seed is one of the main inputs in all cropping systems. Farmers take utmost care in seed selection as poor quality seed material can result in poor harvests and even crop loss. Seed systems can be classified as farmer and formal seed systems. In the target areas in north coastal Andhra Pradesh, p...
