Not AvailablePeanut bud necrosis disease is one of the major diseases in peanut. Interspecific pre-breeding lines
were identified as resistant to bud necrosis disease. Molecular diversity analysis in 115 lines resistant
to bud necrosis disease using simple sequence repeat markers revealed wide genetic diversity among
lines. Out of 219 bands amplified, 205 were found polymorphic. Polymorphism information content (PIC)
value ranged from 0.5 to 0.94, with an average of 0.82. The cluster analysis and PCoA grouped 115
resistant lines and one susceptible cultivar into three major clusters sharing 58% similarity. Susceptible
cultivar KRG-1 was distantly related to resistant lines NRCGCS-28 and NRCGCS-86. AMOVA predicted
96% variation within population and 4% among populations. NRCGCS-28 and NRCGCS-86 were found to
be moderately resistant and KRG-1 as highly susceptible under artificially challenged inoculation
conditions. The incubation period for appearance of disease symptoms were longer in NRCGCS-28 and
NRCGCS-86 than KRG-1 under artificially challenged inoculation conditions. Thus, the present study
reports additional sources for resistance to peanut bud necrosis disease (PBND).Not Availabl
