Evaluation of Maize Inbred and Hybrids against Fusarium Stalk Rot Caused by Fusarium verticillioides

Abstract

Maize crop is being suffering from many biotic and abiotic stresses and among the biotic stresses diseases causes the major loss of the crop. Among the diseases Fusarium stalk rot caused by Fusarium verticillioides is one of the important disease has to be managed in order to reduce the yield losses. The main objective of this study is to find out the resistant sources of maize which can be used for resistant breeding programme. In our study 50 inbred lines and 50 hybrids were screened against F. verticillioides during Kharif 2018 at college of agriculture V C Farm Mandya. Out of 50 maize inbred lines only 5 lines were scored as resistant and 19 lines were moderately resistant. Out of 50 maize hybrids none of them were resistant and 10 hybrids were moderately resistance. The checks CM 202 (Resistant check) and 30-B07 (Susceptible check) showed resistant and susceptible reaction against F. verticillioides.
