Abstract:

Six promising entries along with two checks showing resistant and moderately resistant reaction to sheath rot of rice at field during screening of advanced genetic material were analysed for biochemical constituent’s changes at pre and post inoculation stage (7 days after inoculation of S. oryzae) under pot condition during kharif 2019. The results revealed that, total soluble sugar, reducing sugar, non-reducing sugar, total soluble protein, total phenol and total silica content estimated in rice leaves of all the genotypes were significantly influenced at pre and post inoculation stage. Total soluble sugar, reducing sugar, non-reducing sugar and total soluble protein was recorded 2-4 folds more in highly susceptible genotype (GR-11). It was drastically reduced by 31.33, 28.11, 35.11 and 31.12 per cent, respectively over pre inoculated stage in the plants artificially inoculated with S. oryzae at 7 days after inoculation, followed by moderately resistant genotypes (NVSR-355, NVSR- 2565 and NVSR- 389) and minimum in resistant genotypes (Sambha mahsuri, NVSR-317, NVSR-411 and NVSR-405), respectively. The total phenol and total silica content was 2-3 folds more in highly resistant (Sambha mahsuri, NVSR-317, NVSR-411 and NVSR-405) and moderately resistant (NVSR-355, NVSR- 2565 and NVSR- 389) genotypes compared to susceptible genotype (GR-11) at 7 days after infection. Therefore, considering all biochemical parameters, NVSR-317, NVSR-405 and NVSR-411 rice genotypes with lower levels of total soluble sugar, reducing sugar, non-reducing sugar and total soluble protein content and higher levels of total phenol and total silica content were found resistant to sheath rot disease induced due to S. oryzae as compared with susceptible genotypes.
