Bacterial wilt of potato

Ralstonia solanacearum is the causal agent of bacterial wilt, a devastating plant disease responsible for serious economic losses especially on potato, tomato, and other solanaceous plant species in temperate countries.

Seed-borne diseases are a major problem in Kenya since many farmers have no access to certified seeds. The objective of the study was to study the influence of potato seed production systems on potato seed borne diseases. A survey was carried out in five major potato growing counties in various agro-ecological zones (AEZs).

The evaluation study was conducted for different potato varieties and local genotypes collected from different parts of Chhattisgarh and screened against bacterial wilt and viral diseases complex. The locally collected genotypes have been further categorized on the basis of their distinct growth, yield, quality and disease and insect pest reactions behaviour. The study was carried-out at Department of Vegetable Science, IGKV, Raipur, Chhattisgarh in consecutive years i.e. 2013-14 to 2018-19.

Quantitative trait locus (QTL) mapping is a highly effective approach for studying genetically complex forms of plant disease resistance. With QTL mapping, the roles of specific resistance loci can be described, race-specificity of partial resistance genes can be assessed and interactions between resistance genes, plant development and the environment can be analysed (Young, 1996). DNA markers tightly linked to quantitative resistance loci (QRLs) controlling QDR can be used for marker-assisted selection (MAS) to incorporate these valuable traits.

Ralstonia solanacearum is an aerobic non-sporing, Gram-negative plant pathogenic bacterium. R.solanacearum is soil-borne and motile with a polar flagellar tuft. It colonises the xylem, causing bacterial wilt in a very wide range of potential host plants. It is known as Granville wilt when it occurs in tobacco. Bacterial wilts of tomato, pepper, eggplant and Irish potato caused by Ralstonia solanacearum were among the first diseases that Erwin Frink Smith proved to be caused by a bacterial pathogen.
