“…The glume opening distance was also noted to be relatively narrow compared to the KB susceptible lines. However, Aujla et al (1990) declared the compact arrangement of spikelets as one of the morphological features associated with KB resistance, but Singh (1992) could not observe a significant role of spike compactness in KB resistance in his artificial inoculation-based experiment. It might be because the teliospores germinate directly inside the glume through boot injection and thus surpass the morphological barrier already, which is similar to how durum wheat and triticale lose their resistance when inoculated artificially.…”

Wheat ( Triticum aestivum L.) crop health assumes unprecedented significance in being the second most important staple crop of the world. It is host to an array of fungal pathogens attacking the plant at different developmental stages and accrues various degrees of yield losses owing to these. Tilletia indica that causes Karnal bunt (KB) disease in wheat is one such fungal pathogen of high quarantine importance restricting the free global trade of wheat besides the loss of grain yield as well as quality. With global climate change, the disease appears to be shifting from its traditional areas of occurrence with reports of increased vulnerabilities of new areas across the continents. This KB vulnerability of new geographies is of serious concern because once established, the disease is extremely difficult to eradicate and no known instance of its complete eradication using any management strategy has been reported yet. The host resistance to KB is the most successful as well as preferred strategy for its mitigation and control. However, breeding of KB resistant wheat cultivars has proven to be not so easy, and the low success rate owes to the scarcity of resistance sources, extremely laborious and regulated field screening protocols delaying identification/validation of putative resistance sources, and complex quantitative nature of resistance with multiple genes conferring only partial resistance. Moreover, given a lack of comprehensive understanding of the KB disease epidemiology, host-pathogen interaction, and pathogen evolution. Here, in this review, we attempt to summarize the progress made and efforts underway toward a holistic understanding of the disease itself with a specific focus on the host-pathogen interaction between T. indica and wheat as key elements in the development of resistant germplasm. In this context, we emphasize the tools and techniques being utilized in development of KB resistant germplasm by illuminating upon the genetics concerning the host responses to the KB pathogen including a future course. As such, this article could act as a one stop information primer on this economically important and re-emerging old foe threatening to cause devastating impacts on food security and well-being of communities that rely on wheat.

A basic meal consumed by people all over the world, wheat is traded more globally than all other crops combined. Tilletia indica is the cause of Karnal bunt, also known as "Partial bunt," which affects wheat and is one of the most significant seed-borne diseases. It has significant effects on the wheat trade because most importing nations require that there be no trace of Karnal bunt in wheat imported. To assess responses to disease, ten different genotypes of wheat were sown in matched rows. We planted K1006 and PBW343, two susceptible checks, following each genotype. An athichmist was established for a duration of thirty days, and all suggested agricultural practices were adhered to. The genotypes that demonstrated resistance to the pathogen (below 10% disease intensity) were PBW 343 and K-1006 (2 genotypes). The genotypes with a modest response were K-9107 and K-9162 (two genotypes with a score below 15%). The reactivity of the K793 and K 9006 2 genotypes was somewhat sensitive (below 40% score). The genotypes K9465 HD 2824, K0307, and C306 all showed extremely sensitive reactivity (score exceeding 40%).
