摘要

The stability of high productivity of modern rice varieties is greatly affected by insect pests. Rice gall midge is a serious insect pest of rice that is prevalent in several south eastern Asian countries. Gall midge resistance has been mainly attributed to antibiosis. No progress has so far been made in identifying the exact biochemical nature of resistance. In Indica subspecies the understanding of chemical nature of disease would be helpful in the control of the disease and also in breeding programme aimed at developing resistance varieties. Studies were undertaken to establish the biochemical basis of resistance. Biochemical characterization of resistant and susceptible varieties were carried out. The parameters considered were: total sugar and reducing sugar content, total phenol content, amino acid profile, post infectional changes in sugar and phenol, isozyme studies. 2 figs, 6 tabs.
