Keywords:
Early maturity, Genotypes, Fusarium ear rot, Maize, ResistanceAbstract
In order to investigate the amount of resistance in and early maturity lines and hybrids to ear rot fusarium disease, an experiment was caried out with 56 lines and 34 hybrids which were extracted from material corn and forage crop department were planted in Gharakhil agricultural research station in 2010-2011. Inter row space was 75 centimeters, row legth was 2/5 m and pland distance in row was 25 centimrters. By using artifical inoculation, all of gonotyps were inoculated by using scale rating, the rate of resistance was indentfied (Diseas severity) and the result in2010 showed that three lines were very suseptible, 11 lins were susceptible and others were tolorant. Two hybrids were susceptibl and others tolorant. Results in 2011 showed that five lines were susceptibleand12 lines were very tolorant. Hybrid, KE77007/14 × KE1264/5-1 was resistant, 31 hybrids were tolorant and one hybrid was susceptibl.References
