Studies were conducted to evaluate resistance or susceptibility of eleven rice accessions against yellow stem borer, S. incertulas based on morphological traits. In this current investigation, stem diameter was significantly higher in susceptible accessions like TN-1 (5.003 mm), BA-270 (4.686 mm) and BPT-5204 (4.453 mm). However, most minimal measure of stem diameter was observed in resistant accessions Viz., BA-132 and BA-155 (3.610 and 3.746 mm), respectively. Meanwhile, the maximum quantity of wax content was noticed in resistant accession BA-132 (0.95 mg/g on leaves and 0.74 mg/g on stems). This was however less in susceptible accession TN-1 (0.15 mg/g on leaves and 0.13 mg/g on stems), respectively. Trichome density was maximum on BA-132, BA-155 and BA-147 (112.00, 96.00 and 86.00 numbers per cm². However, the lower trichome density was observed on TN-1 and BA-270 (14.67 and 18.33 numbers per cm²).
