Abstract:

Peanut bud necrosis disease is one of the major viral diseases in peanut. Interspecific peanut pre-breedinglines along with susceptible checks (KRG-1 and TMV2) were tested under field conditions at hot spot location over two seasons. Out of 34 lines, 16 lines were found resistant, while 16 were moderately resistant. Significant negative association was observed between PBND incidence and phenol content, number of trichomes on leaf, petioles and stem. While significant positive association was observed between PBND incidence and total soluble sugar, free amino acid and leaf thickness. Higher phenol content, number of trichomes on leaf, stem and petioles and dark green leaf colour might have contributed a major role in imparting resistance to PBND in these peanut lines. Pre-breeding lines NRCGCS Nos. 79, 86, 159 and 301,belong to virginia habit group, were found with less disease score, higher amount of phenol, more number of trichomes on leaf, stem and petioles and dark green leaf color compared to susceptible checks. These interspecific pre-breeding lines would be fresh sources for resistance to PBND for peanut breeding programme.
