Symptom based artificial screening of promising maize germplasm against Chilo partellus (Swinhoe)

Ram Kumar, Tanweer Alam and Arbind Kumar Rai

The present investigation was carried out at the research farm of the Tirhut College of Agriculture, Dholi, Muzaffarpur (Bihar) during Kharif 2016 to screen out the different maize germplasm against Chilo partellus (Swinhoe). The study revealed that among the different maize genotypes screened; IIMRQPMH 1608, FQH 106 and IIMRQPMH 1606 were found least susceptible while the genotypes IIMRQPMH 1604, IIMRQPMH 1502 and IIMRQPMH 1602 were found susceptible. Correlation result between plant height and the damage caused by C. partellus showed that percent plant infestation (-0.348), mean tunnel length (-0.439) and mean leaf injury (-0.332) evinced negative but non-significant effect on plant height. However, mean no. of exit holes (-0.514*) rendered negative and significant effect on plant height.
