Resistance of early maturity maize genotypes to southern corn leaf blight
In order to study the resistance of early maize genotypes to Southern Corn Leaf Blight (SCLB) or Maydis Leaf Blight (MLB), RCBD experiments with 20 inbred lines and hybrids in 2014 and 16 genotypes in 2015 were conducted at Karaj and Sari Stations. Inoculation was carried out with spore sus...

| description | In order to study the resistance of early maize genotypes to Southern Corn
Leaf Blight (SCLB) or Maydis Leaf Blight (MLB), RCBD experiments with 20
inbred lines and hybrids in 2014 and 16 genotypes in 2015 were conducted at
Karaj and Sari Stations. Inoculation was carried out with spore suspension
using syringe (3ml/each whorl) firstly at 3-4 leaf stage of maize, and then,
sorghum grain inoculated with fungus was applied at 6-8 leaf stage in whorl
of each plant using the bazooka technique. Evaluation was done on the basis
of disease progress at pollination stage and two weeks after pollination
stage with scale 0-5. The results of variance analysis and mean comparison
showed that there are different reactions among genotypes to disease. In
this study, in 2014, 15% genotypes categorized into resistant group, and
these were genotypes: KE 77003/10 × KE 75039, KE 72012/12 × K1263/1 (KSC
400), and K 2331 × KE 75039. Among 16 genotypes in 2015, three hybrids - No.
16 with pedigree (KE 76009/311× K 1264/5-1), No. 10 with pedigree (K 2331 ×
KE 75039) and No. 9 with pedigree KSC 400 (KE 72012/12 × K1263/1) - were
identified as resistant hybrids that can be a good source of resistance to
SCLB. |
