Abstract
Fusarium wilt is a famous disease of tomato all over the world. The use of resistant varieties is the most efficient approach to control the disease. The current study was carried out to investigate the presence of marker gene(s) resistant to Fusarium wilt in tomato germplasm, and the subsequent use of resistant varieties to contain the disease. Thirteen varieties: Pusa ruby, Pant bahar, Punjab chhahara, Arka alak, Arak abha, Ratan, CLN-2116-B, CLN-1767-238-2Y, CLSN-2123-A, CLN-1621-E, CLN-1621-T, CLN-1621-L, and CLN-2026-C were screened for the presence of I-3 resistance gene, a marker known to confer resistance to the race 2 of F. oxysporum f. sp. Lycopersici. Two varieties, Arak abha and Ratan were tested positive for the presence of I-3 against the race 2 of the pathogen.
