Abstract:

Out of 419 peanut interspecific derivatives, screened over four seasons in epiphytotic field (Hot spot location) and glasshouse conditions, seven genotypes viz., CS-43, CS-54, CS-55, CS-73, CS-77, CS-82 and CS-104 were confirmed as potential resistant with least disease incidence, high dry pod yield, desirable yield and pod features besides longer DFSA, DLSA and t50. Further significant positive correlation was found between t50 and DFSA, PBND (%) and DLSA. However, negative correlation was recorded between PBND (%) and t50, PBND (%) and DFSA. In glasshouse test, all cross inoculated with PBNV and subsequently produced leaves of resistant genotypes showed presence of virus revealed the block in the systemic virus movement. Perhaps this is first attempt in searching for PBND resistance in interspecific derivatives of peanut and these genotypes can be better utilized in resistant breeding programme for PBND resistant agronomically high yielding varieties.
