Response of a local rice variety Pandanwangi to infection of bacterial leaf blight Xanthomonas oryzae pv. oryzae strain III, IV, and VIII

Abstract

Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) is one of the limiting factors in rice production. A local cultivar, rice “Pandanwangi” is a superior variety much preferred and cultivated by the farmers in Cianjur, West Java, Indonesia. The information about the response of “Pandangwangi” to Xoo is still poorly understood. This paper reports the results of the evaluation of “Pandanwangi” response against BLB. This research was conducted in a greenhouse with artificial inoculation using Xoo strains III, IV, and VIII with bacterial suspension at 108 cfu.mL−1. The results showed that the response of cv Pandanwangi to Xoo infection was different from the strain of Xoo. “Pandanwangi” cultivar was susceptible to Xoo strain III and VIII and very susceptible to strain IV.

Marker-assisted Breeding and F3 Progenies Characterization for Improving Local Rice Variety “Tinggong”

“…In addition, the varieties of containing Xa21 and Xa5 genes were resistant to almost Asian Xoo strains. Indonesian rice cultivar Pandan Wangi" Marker-assisted Breeding and F 3 Progenies Characterization for Improving Local Rice Variety "Tinggong" was susceptible to Xoo strain III and VIII and very susceptible to strain IV (Hadiwiyono et al, 2021).…”
