Abstract
ABSTRACT: Rice is the most important staple food crops for more than half of the world’s population. The stem borer Chilo agamemnon Bles, is one of the most devastating pests of rice, reducing yield worldwide. The use of resistant cultivars remains one of the most reliable methods to pest's management. In this study, some rice genotypes were genetically assessment for the stem borer resistance. Two varieties, Sakha101 (Egyptian rice variety, resistant to stem borer) and Giza178, (Egyptian rice variety, susceptible to stem borer) and their F1, F2 and F3 were evaluated. Results showed that resistance to stem borer appears to be under polygenic control. Identifying microsatellite markers association to stem borer resistance was another objective of this investigation. Five markers (RM164, RM166, RM263, RM201 and RM566) showed polymorphism among susceptible and resistant genotypes. However, RM263 and RM201 showed complete association with resistance The SSR markers would be helpful in the breeding program application.
