VIRULENCE / AGGRESSIVENESS TESTING OF
XANTHOMONAS ORYZAE PV. ORYZA ISOLATES CAUSES BLB DISEASE IN RICE CULTIVARS OF
PAKISTAN
Abstract: In present study, virulence and aggressiveness of seven
Xanthomonas oryzae hypersensitive isolates, (Xoo 20, Xoo 36, Xoo 51,
Xoo 65, Xoo 74, Xoo 99 and Xoo 105) were tested on seven rice varieties
(Basmati 385, IRRI 26, Basmati 386, Dilroosh 97, JP 5, Super Basmati,
Basmati 2000 and Ks 282), through detached leaf, glass house and field
assays Xoo 99 showed most aggressive reaction on detached leaves and
Xoo 105 exhibited more aggressive reaction on glass house plant and
field assay as compared to other isolates. Moreover, all rice tested
cultivars showed susceptibility against isolates of BLB disease, Basmati
385 were showed more susceptible reaction. 1Department of Plant Sciences SBKW University, Quetta, Pakistan 2Department of Botany, Government College University Faisalabad, Pakistan 3Nust Center of Virology & Immunology National University of Sciences & Technology H-12, Islamabad, Pakistan 4National Agricultural Research Council (NARC), Pakistan Islamabad. *E-mail: rukhseea@yahoo.com; Phone 92-81-2862088; Fax 92-081-2856180 |
