Multilocational evaluation of promising advanced breeding lines for resistance to rice tungro viruses

Discipline: Agriculture, Pest Management

 

Abstract:

An important objective of IRRI's breeding program for irrigated rice ecosystems is to develop varieties with resistance to rice tungro viruses in order to achieve durable resistance to tungro disease. We conducted this study to monitor tungro virus and leafhopper vector variability between test locations, based on the reaction of selected varieties and advanced breeding lines with different sources of resistance.
