Abstract

Fusarium wilt (Fusarium oxysporum Schlecht. f. sp. melongenae) is one of the most destructive diseases of eggplant (brinjal) in India. It is a soilborne disease and its control is very difficult. Therefore, host plant resistance is the best way to cope with this problem. In the present study a total of eighty cultivated genotypes includingreleased varieties and twelve wild accessions of six different species (Solanum incanum, S. insanum, S. aethiopicum, S. integrifolium, S. sisymbrifolium and S. khasianum) were evaluated under field conditions during the years 2014-2015 and 2015-2016. The observation of visual symptoms was taken at 95 days after transplanting and finally disease incidence was calculated. Fusarium wilt incidence showed statistically significant variation among the genotypes under the present trial. Among the genotypes evaluated, highest wilt incidence wasrecorded in Sel 129-5 (95% in 2014-2015 and 96.25% in 2015-2016) and the lowest wilt incidencewas recorded in Pusa Bhairav (4% in 2014-2015 and 2.08% in 2015-2016) and G-32 (5.4% in 2014-2015 and 6.25% in 2015-2016). Among the wild accessions S. khasianum and S. sysimbrifolium were having 0% wilt incidence in both the year. Among all the genotypes including wild accessions G-32, Pusa Bhairav, G-164, G-65, S. khasianum, S. sysimbrifolium, S. integrifolium (AC-2) were found to be highly resistant. Validation of the resistance reaction of the genotypes and wild accessions is required in artificial epiphytotic condition before utilizing them in breeding programme.
