Twenty maize genotypes were screened for resistance against shoot fly during spring 2013 and 2014. Observations were recorded on the parameters viz., (i) % plants oviposited, (ii) no of eggs laid, (iii) % deadheart formed, (iv) plant height, (v) days of oviposition, (vi) no of maggots/10 plants, and (vii) weight of maggots. Maximum % oviposition was observed in DC-2 (both years), whereas minimum was in WP-21 in spring 2013 and HKI-323 in spring 2014. The infestation level was too heavy and all the evaluated genotypes were oviposited with. Maximum eggs were laid on DC-2 and the least with HKI-1011. During 2013 and 2014, maximum % of deadheart was observed with DC-2, while the least one was with WP-21 (2013) and in HKI-1011 (2014). The maximum weight of maggot was observed with DC-2 and the least with WP-21 (2013); in 2014, it was observed with JCY-2-7 and WP-21, respectively. Thus the % plants oviposited, number of eggs laid, % deadheart formed, number recovered and weight of maggots indicates the genotype susceptibility level. These levels could be used as marker traits for resistance to shoot fly in maize. Not Available |
