Relevance of Chemical Constituents in Conferring Tolerance to Yellow Stem Borer, Scirpophaga incertulas Wlk in Rice

Tolerant rice accessions were identified from a field study involving 196 at Pandit Jawaharlal of Agriculture and Research Institute, Karaikal for yellow stem borer, Scirpophaga incertulas. in along with the susceptible check (TN1) considered analyzing biochemical parameters viz., chlorophyll content, total sugars, reducing phenols, soluble protein, proline. Higher amounts moderate lesser sugars as factors imparting resistance against this pest resistant entries. The correlation among infestation percentage parameters, revealed strong positive between percentage; negative phenols implying role plant defense borer.
