The potato, being an underground vegetable crop, faces consistent threats from soil- and tuber-borne fungal and bacterial pathogens. Black scurf and stem canker disease caused by the fungal pathogen Kuhn is a critical global concern in the potato cultivation system. In this study, we evaluated the disease mitigation potential of five systemic acquired resistance-inducing chemicals , salicylic acid, jasmonic acid, -aminobutyric acid, -aminobutyric acid and hydrogen peroxide (HO).

In a line × tester mating design, ten susceptible lines and four resistant testers were used to conduct genetic analysis. The significance of general combining ability (GCA) and specific combining ability (SCA) variances revealed that both additive and non-additive gene actions were involved in the inheritance of Sclerotinia stem rot resistance and yield attributing traits.

The study of the genetic and proteomic basis of resistance to this disease is imperative for its effective utilization in developing resistant cultivars. Therefore, the genetic pattern of Sclerotinia stem rot resistance in Indian mustard was studied using six generations (P, P, F, F, BCP, and BCP) developed from the crossing of one resistant (RH 1222-28) and two susceptible (EC 766300 and EC 766123) genotypes.

Among them, the hemibiotroph , which causes sclerotinia rot disease, is the most devastating fungal pathogen causing up to 90% yield losses. The availability of host resistance is the only efficient approach to control and understand the host-pathogen interaction.

Fourteen isolates of were collected from different locations of mustard growing regions of India and were studied for cultural, morphological and molecular variability at CCS HAU, Hisar. Variability was observed for colony colour, type of growth, diameter of mycelial growth, sclerotia initiation, number and pattern of sclerotia formation among the isolates. Mycelial growth and sclerotia initiation were faster in Bhiwani isolate as compared to others.
