The best approach to manage this pest is the development and use of maize cultivars having genetic resistance. In the cultivar development process, germplasm needs to be precisely evaluated on a large scale utilizing insect mass rearing techniques, synthetic diets, and artificial infestation of plants. Insect rearing laboratories have been set up and synthetic diets developed and improved. Extensive evaluation of germplasm by Punjab Agricultural University, Directorate of Maize Research and other institutes in India led to the identification of some relatively resistant materials. The more promising ones are populations Antigua Gr. 1, Arun, D 791, J 22, J 3022, Pool 27 and Tarun, and inbred lines CML 67, CML 71, CML 72, (Partap x Mo17.B57)-17(S6), Suwan 1(S) C6-40(S5) and Suwan 1(S) C6-53(S5). Further, MBR-SCB Res. EV (Y), MBR 86-Stars and Diamonds and Pop. 24 Bulk were identified to be resistant to C. partellus and Ostrinia furnacalis Guenee. Populations Parbhat and Navjot, and inbred lines CM110L, CM 201, J101(52), J663(S7) and Vijay 444(S2) showed resistance to C. partellus, maydis leaf blight [Drechslera maydis (Drechsl.) Nisikado and Miyakil and brown stripe downy mildew (Sclerophthora rayssiae var. zeae Payak and Renfro). Many of these materials have been used to develop open pollinated and hybrid cultivars and to derive inbred lines. In Ageti 76, Navjot and Kiran, two to three cycles of recurrent selection for resistance to C. partellus under natural conditions led to appreciable gains. In Ageti 76, selection was carried out only for insect resistance, whereas, in Navjot and Kiran, selection criteria were based on grain yield and other traits including insect resistance. In J 22, four cycles of recurrent selection for borer resistance under artificial infestation resulted in a significant improvement of this trait.Collection: CIMMYT Publications Collection
