ABSTRACT
In vivo experiment was conducted to screen 56 genotypes for resistance to early shoot borer, Chilo infuscatellus Snellen at Zonal Agricultural Research Station, V.C farm, Mandya during 2014-2015. Among the 56 genotypes, 47 genotypes were found less susceptible, while nine genotypes were found moderately susceptible to early shoot borer. Among these 16 genotypes, 009-64(3.44%), 10-65-01(5.59%), 10-65-01(3.83%), 10-17-08(4.97%), 10-57-07(12.65%), 07-10-02(10.57%), 10-28-02(10.03%), 09-61-02(14.85%), 10-17-05(15.39%), 07-06-05(16.48%), 10-33-33(17.75%), 10-38-06(29.86%), 08-15-06(25.88), 06-09-03(27.45) and checksCoVC99463(4.83%) and Co 86032(22.39%) were selected to find out the antibiosis mechanism associated with them.
Correlation study on the biochemical constituents of 16 selected genotypes and checks with the cumulative incidence of ESB revealed positive correlation with total sugars (r= 0.80*) and reducing sugars (r= 0.82*). Whereas phenols (r= -0.84*), cellulose (r= -0.80*), silica (r= -0.82*) and lignin (r= -0.79*) showed negative correlation with ESB incidence. So biochemical analysis of the genotypes indicated lower quantity of total sugars and reducing sugar and higher quantity of phenols, cellulose, lignin and silica were found imparting resistance to ESB of sugarcane.
