Abstract

Ralstonia solanacearum is a soil-borne bacterial pathogen and a major limiting factor in the production of many crop plants around the world. The present study was conducted in Rabi, 2021 at the Postgraduate Research Block, Department of Vegetable Science, College of Horticulture, Sri Konda Laxman Telangana State Horticultural University, Rajendranagar, Hyderabad. The current study examined 25 genotypes for Bacterial wilt resistance at the morphological level. Twenty-five genotypes of tomato and brinjal including susceptible checks (Arka Vikas and Pusa ruby) were screened under artificial inoculation conditions in poly bags. Out of 25 genotypes, three were found highly resistant (HR) viz., Arka Keshav, Surya, Solanum torvum, one genotype i.e. LA -0490 is resistant (R), two genotypes i.e. EC-631379, LA-1589 were recorded moderately resistant (MR),one genotype i.e. EC-620509 is moderately susceptible (MS), fourteen genotypes viz., EC-620428, EC-620378, EC-620389, EC-620394, EC-631369, EC-620503, AVTO-9803, EC-620452, Money maker, Marutham, Pusarohini, Pusasheethal, PKM-1 and Arka Vikas were susceptible (S) and four genotypes i.e. EC-615055, EC-620422, EC-620441 and Pusa ruby were recorded highly susceptible (HS) to bacterial wilt. Genotypes exhibiting Bacterial wilt resistance will be grafted on to commercial variety of tomato and evaluated under open field conditions for yield, quality parameters and disease resistance under Telangana conditions.

Conclusion

Results from bacterial wilt screening revealed that Arka Keshav, Surya, Solanum torvum showed high resistance (HR), LA -0490 is resistant (R) and two genotypes i.e. EC-631379, LA-1589 were recorded moderately resistant (MR) against Ralstonia solanacearum.
