A laboratory method for evaluating maize germplasm to banded leaf and sheath blight

Ahuja, S. C.; Payak, M. M.

Excised leaf pieces from 30-day-old plants of 31 entries were floated on kinetin solution in Petri dishes and an infected barley grain was placed on the adaxial surface of each piece near the midrib. The inbred lines CM103, CM104, CM105, CM300, CM600 and PI217407 were resistant to the causal organism of banded leaf and sheath blight, Rhizoctonia solani f. sp. sasakii. The method (described) tests infection by Rhizoctonia solani f.sp. sasakii on excised leaf pieces.
