Abstract

In the present study, one hundred maize inbred lines were evaluated for resistance to C. partellus under natural infestation during kharif seasons of 2012-14. The leaf injury rating ranged from 1.2 to 7.7 on 1 – 9 rating scale. The highly resistant germplasms (< 2.0 score) included HUZM-67, HUZM-70-1, HUZM-211-1, CM-211*-2-1-1, POP-34-C8-1, HUZM-597-2, HUZM-366, HUZM-714, HUZM-390-2, HUZQPM-4, HUZQPM-5, HUZQPM-6, HUZQPM-7, HUZQPM-8, while 34 inbred lines along with the resistant check were found to be resistant with damage ranging between 2 – 3. The maize inbred lines HUZM-36, HUZM-47, HUZM-58-2,   HUZM-79, HUZM-242, HUZM-152-2, HUZM-265,  HUZM-343-1, HUZM-350-1, HUZM-356, HUZM-386-1, HUZM-488, HUZM-513-1, HUZM-628-3, 193-1, HUZM-229, HUZM-391-2, HUZM-5, HUZM-6, HUZQPM-1 were found to be susceptible (score from 5.2 – 7.5) and remaining genotypes were found moderately resistant. Significant variations were observed in leaf injury rating (LIR), mean tunnel length, per cent dead heart and mean plant height among the different inbred lines screened. The damage parameters like mean tunnel length and per cent dead heart exhibited a significant positive correlation with foliar damage while the plant height exhibited a significant negative correlation with the foliar damage rating.
