Published on

Two hundred forty five accessions of sugarcane including Saccharum
officinarum, S. barberi, S. sinense, foreign commercial cultivars of Barbados, Canal Point,
Hawaii, Mauritius, Queensland, Africa, Argentina, Jawa and Indian commercial cultivars
were evaluated against the top borer pest under natural infested condition. Twelve
au<!ssions (4.9%) were found resistant, 79 (32.30/.) were moderately resistant, 152 (62.0%)
were susceptible and only 2 (0.8%) were highly susceptible. Maximum percentage (18.2%)
of accessions of S. barberi were resistant to top borer infestation, followed by foreign
commercial cultivars (10.5%), and Indian commercial cultivats (2.3%).
