Abstract:

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., 8 lines from H4 - Arka Vikas x PSR11668 (S. pimpinellifolium), 10 lines from H6 - Arka Vikas x EC519809 (S. peruvianum), 8 lines from H17 - CO3 x EC519791 (S. habrochaites), and 9 lines from H27 - PKM1 x EC519791 (S. hirsutum) were screened under natural field condition. In order to create favourable environment for PBNV infection, the most susceptible host plant cowpea var. Co (Cp)-7 was planted between every two rows of tomato. No insecticide spray was given during entire crop production period. The disease incidence was assessed on 30th, 45th, 60th and 90th day after transplanting based on Percent Disease Incidence (PDI %) and disease reaction scale. The results revealed that, PBNV disease infection was seen in all the stages of crop growth. Among the four interspecific hybrids, maximum degree of field resistance was observed in 3 lines in.,  H6 - Arka Vikas x EC519809 (S. peruvianum) followed by 2 lines in H4 – Arka Vikas x PSR11668, 2 lines  in H17 – CO3 x EC519791 and 1 line in H27 -  PKM-1 x EC519791. These 8 resistance lines will be further screened under artificial condition and field condition for confirming the resistance to PBNV and the plants showing resistance will be released as PBNV resistant variety or it may be used as a source for PBNV resistance in tomato breeding programmes.
