Abstract:
Maize is the leading cereal worldwide with wide adaptability and higher productivity potential. The present study involved field evaluation of seven inbred lines, four testers and twenty eight hybrids for resistance against TLB disease along with yield under artificially inoculated field conditions in RCBD using 5 checks at University of Agriculture Science Dharwad during kharif, 2020-21. Out of eleven inbred lines (7 lines and 4 testers) three lines had shown resistance reaction, three inbred lines showed medium resistance, two lines had showed medium susceptible reaction and two inbreds lines showed susceptible reaction to TLB reaction respectively. Out of twenty eight hybrids, five hybrids showed resistance reaction, Four hybrids showed moderately resistance reaction, fourteen moderately susceptible and five had shown susceptible reaction. Thus the inbreds and hybrids identified to possess low disease severity score against TLB would be helpful for their deployment in future breeding programs and eventually could be used in developing promising genotypes having desirable level of resistance in disease endemic areas to aim for sustainable productivity.
