Banded leaf and sheath blight of maize: Its importance and current breeding efforts - Los Baños, Laguna (Philippines) PCARRD : 2000 - 6 pages - Printed
Banded leaf and sheath blight (Rhizoctonia solani f sp. sasakii) is one of the economically imp diseases of maize in many countries of tropical Asia. Losses in grain yield have been estimated in the of 23.9 to 87.5 percent depending on the disease severity. The genetic variability for resistance has found to be limited, which puts limitation on resistance breeding. A number of maize genotypes in China and Korea have been found to possess tolerable level of resistance. However, resistance of materials needs a thorough' evaluation on multilocation basis before they are mobilized in the na breeding programme (s). Selection and improvement of suitable genotypes for resistance has been act through collaborative project introduced by CIMMYT and national programmes in Asian region. expected that through this coordinated activity useful resistant germplasm will be made available it future.
