Varietal reaction of non‐senescent sorghums to the pathogens causing root and stalk rot of sorghum in India uri icon

abstract

  • Twenty?five non?senescent sorghum genotypes were screened for stalk rot reaction against the five stalk rot pathogens inoculated individually by the toothpick inoculation method under field conditions. Five genotypes (Q 101, Q 102, Q 103, Q 104 and PQ 54) were found resistant (<5% plants lodged) against all the five stalk rot pathogens. More greener leaf area at physiological maturity, confirmed the resistance in the non?senescent sorghum genotypes. E 36?1, a stalk rot?resistant genotype, showed resistance against all the pathogens except Fusarium moniliforme. There was strong positive correlation between all the stalk rot disease evaluation parameters
