The book entitled screening of rice entries against yellow stem borer is a author's Master degree research Work. This book consists of topics on the evaluation of rice entries against yellow stem borer and biochemical parameters for resistant entries. This study was undertaken during 2012 - 2013 in Pandit Jawaharlal Nehru College of Agriculture and Research Institute (TNAU),Karaikal, India. For the screening work totally 196 rice entries including three susceptible check has been collected from Directorate of Rice Research and used for field experiment. The data has been recorded during vegetative stage and flowering stage. Top five resistant entries and one susceptible check TN1 has been used for biochemical analysis. The results showed that the plant biochemicals plays major role in their resistant mechanisms.
