Abstract: The Indian soybean field impacted a lot by catastrophic disease called charcoal rot, causal organism is Macrophomina phaseolina (Tassi). In 2020, seven genotypes of soybean were evaluated for their charcoal rot resistance in hotspot region, Amravati, Maharashtra. The seven genotypes underwent field evaluation in 2020 and 2021, targeting on disease reaction and agronomic traits. The evaluations employed Percent Disease Incidence (PDI), Area under Disease Progress Curve (AUDPC), and grain yield as key criteria. Among the genotypes, AMS-1001 demonstrated the lowest PDI (2.14) and AUDPC (8.37) values in 2020, along with the highest grain yield. These findings underscore the potential of AMS-1001 as a high-yielding, charcoal rot resistant genotype, highlighting its suitability for inclusion in breeding programs aimed at enhancing soybean productivity and disease resilience in India.
