Identification of antagonistic microorganisms of maize sudden wilt ((Stenocarpella maydis) Berk. Sutton)

, : Identification of antagonistic microorganisms of maize sudden wilt ((Stenocarpella maydis) Berk. Sutton). CEIBA 36(2): 271-276

Samples from soil, stems, ears, leaves and rhizosphere of 10 maize plants at the physiologically mature stage were collected from 3 localities in Honduras. Tissue samples were washed with a 300 ml saline solution (0.85% NaCl), and 10 g of each soil sample was mixed with 95 ml of the saline solution. Three drops of every dilution (10-3, 10-4 and 10-5) from the suspensions were placed on PDA media and PDAA with growing S. maydis. The plates were incubated for 3 d at 28 degrees C.

Shanks, cobs and kernels of inoculated and uninoculated plants were divided into segments and S. maydis colonization was determined...

The objective of this study was to provide a better understanding of the interrelationship between methods of screening for resistance to ear rot, caused by S. maydis. The inheritance of resistance and the genetic and phenotypic correlation of var...
