Response of rice (Oryza sativa L.) germplasm against Xanthomonas oryzae pv. oryzae (Xoo) under greenhouse conditions in Pakistan
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 7, Issue 3
Abstract
Bacterial leaf blight (BLB) is one of the apex devastating diseases of the rice crop around the world. It continuously reduced the yield and quality of rice. In this investigation efforts have been made to study the response of different rice germplasm against Xanthomonas. oryzae pv. oryzae (Xoo) under greenhouse conditions. Diseased leaves were collected from the major rice growing areas of Punjab during 2011. Thirty five Xoo isolates were purified and confirmed. For pathogenicity test Super basmati rice variety was used. Plants were inoculated with freshly prepared inoculum (109 CFU/ml) of PKXOO4 (an aggressive strain) by leaf clip method. Among 50 lines screened, one was found highly resistant, one was resistant and two were moderately resistant against Xoo. The resistant germplasm identified can be used in breeding rice varieties against Xoo.
