Resistance to Banded Leaf and Sheath Blight of Maize in Asia
The present investigation incorporates results of the Banded Leaf and Sheath Blight (BLSB) evaluation activities undertaken during the year 2002. Multi- location evaluation of maize genotypes was conducted in India (Delhi, Pantnagar), China (Guangxi) and Indonesia (South Sulawesi) to select host resistance against BLSB. A total of 2025 maize genotypes from CIMMYT and India, mainly in inbred background, were artificially inoculated in 35～40 days-old crop to identify stable resistant sources. On the basis of mean disease rating across locations, 24 lines in yellow kernel type and 16 in white kernel type were found to be tolerant. However, because disease development was poor at sites in Indonesia and China, it was decided to rely on disease reaction data only from Delhi and Pantnagar. The average disease rating at the two locations in India ranged from 3.8 to 5.0, thereby indicating optimum level of disease development for screening. Therefore, on the basis of data from India eight materials viz. EY-DMR-G-C5-S2- B-B-3-2-B-B-B-B; SW92145-2 EV-21-1-B-B-B-B; SW92145-2 EV-55-1-B-B-B-B; Pop. 31C4S5B-85-＃-＃-1-4-6-B-B-B; Pop. 147-F2 ＃ 161-3-2-B-1-B; AMAT LOCHS129-1-1-1-2-1- 1-1-BBBB-B; AMATLOCHS71-1-1-2-1-1-1-BBBB-B and AMATLCOHS169-1-1-1-1-2-2-1-B-B in yellow colour and
