“…However, the most potential entry point for bacteria is leaf wounds, especially new wounds compared to old wounds. Later, disease progression characterized by the development of whitish-gray lesions can be influenced by sunlight, disease virulence, and the genetics of the strains used [16].…”

One of the important diseases of paddy plants is bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae (Xoo). Kamba is one of the local paddy plants in Central Sulawesi’s germplasm collection that is superior in origin from the Lore (Bada, Napu and Lindu). Until now, no scientific testing has been conducted on the resistance of local kamba paddy to leaf blight. This study aims to compare the level of resistance of several kamba paddy genotypes to leaf blight caused by the bacterium Xoo This research was conducted at the Disease Laboratory and Plant Pests and Diseases Gauze House, Faculty of Agriculture, Tadulako University, Palu. Stages of research implementation include propagation of Xoo, Preparation of test plants, and Transmission of Xoo. Observation variables include symptoms on plants, incubation period, disease severity and level of resistance to Xoo. The results showed that Paddy cultivars Kamba Bulili Kasar and Kamba Bulili Halus showed resistance reactions to Bacterial Leaf Blight (HDB) caused by Xoo bacteria. Both paddy cultivars also showed a disease incubation period of 6 days, longer than the susceptible comparison varieties.

Detection of seed-borne pathogenic bacteria of northern black wattle (Acacia auriculiformis A. Cunn. ex Benth.). Intensive research of seed-borne pathogen of A. mangium and A. crassicarpa which have been established in industrial timber estate (HTI), while plantings development of northern black wattle in Indonesia 1990 have not recent been established in the 1990s. Very limited information available on northern black wattle diseases especially seed-borne diseases. The objectives of this study were to identify seed-borne pathogenic bacteria of northern black wattle and the effects on seed germination. Methods for the isolation of bacteria were by seed soaking, seed griding, blotter test, growing-on test on paper and soil. Identification of bacteria by PCR used 63F/1387R primer. The results showed that seed-borne bacteria of northern black wattle were Paenochrobactrum sp., Ralstonia sp., Burkholderia cepacia complex, Pseudomonas stutzeri, Acinetobacter sp., Alcaligenes faecalis, Salmonella bongori, Escherichia hermannii while pathogenic bacteria cause seedling leafspot were Micrococcus luteus and Burkholderia cepacia complex. Burkholderia cepacia complex, A. faecalis, Acinetobater sp., P. stutzeri, S. bongori and Ralstonia sp. reduced seed germination and increased rotten seed, suggested that they were the pathogenic bacteria of northern black wattle seed. Ralstonia sp. significantly increased the percentage of rotten seed and decreased shoot length and root length. P. stutzeri and S. bongori significantly inhibited the root growth. Paenochrobactrum sp. and E. hermannii were assumed as pathogen with weak virulence due to seed germination, the percentage of rotten seed and vigour index were relatively similar to untreated seed.

“…22 IRBB lines, five new high yielding varieties, 22 local varieties (Susanto and Sudir 2012), and some promising lines (Yuriyah et al 2013). Local rice varieties resistant to Xoo identified from Banten (Ali et al 2012), Sulawesi (Khaeruni et al 2016), and Aceh (Hadianto et al 2015). Although the resistance characteristics of released rice varieties showed to most dominant Xoo pathotypes, they might have no longer effective to control the BLB in the fields due to changing of new Xoo pathotypes (Sudir and Suprihanto 2006, Suprihatno et al 2010, Susanto and Sudir 2012, Khaeruni et al 2016.…”

Hundred of high yielding and bacterial leaf blight (Xanthomonas oryzae pv. oryzae, Xoo) resistant rice varieties released since the 1960s are important sources of genetic materials for exploring superior genotypes. The study aimed to evaluate the genetic resistance of 177 rice varieties to Xoo and their agronomic traits. The evaluations were conducted at the Indonesian Center for Rice Research Experimental Station during the wet season (December 2015-March 2016). The bacterial leaf blight resistance was evaluated for Xoo pathotypes III, IV, and VIII using the clipping method. The genetic variation among genotypes was categorized as low (0–10%), medium (10–20%), and high (>20%), whereas the heritability was categorized as low (0-30%), medium (30-60%), and high (>60%). The variability of resistance to Xoo pathotypes, grain yield, and spikelet fertility was low, while the variability of plant height, productive tiller number, filled grain, and total spikelet was medium, and the variability of unfilled grain number was high. The 29 varieties were categorized as superior based on their agronomic traits or resistance to Xoo pathotypes. In conclusion, Batutegi and Fatmawati were superior in the total spikelet number, while Rojolele and Inpari 2 were supreme in the thousand-grain weight. Dodokan had a very short maturity, and Inpari 24, Conde, Kalimas, Angke, Inpari 17, and Inpara 8 had the highest resistance to Xoo pathotypes. The study implies that the identified rice superior genotypes could be used as genetic materials to design cross combinations for higher yield potential and BLB resistance varietal improvement.
