Peanut bud necrosis disease

Field screening of F3 generation interspecific tomato hybrids derived lines for resistance to Peanut bud necrosis virus (PBNV) was carried out in the Department of Horticulture, Agricultural College and Research Institute, Madurai, Tamil Nadu Agricultural University, Tamil Nadu, during 2019-2020. PBNV is the most destructive and economically important plant virus in tomato which causes yield loss up to 80 to 100 per cent. The present study was formulated to develop PBNV resistant lines in tomato suitable for commercial cultivation. Totally 35 lines from four interspecific crosses Viz.

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.

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.
