Genetic analysis of resistance to Macrophomina phaseolina (Tassi) Goid in maize (Zea mays L.)
Abstract
The inheritance of resistance to the causal agent of charcoal stem rot Macrophomina phaseolina (Tassi) Goid, and water content in the internode below the ear was analyzed by Generation Mean Analysis over two years at two locations in Vojvodina. Chosen for the study were six crosses that had previously been determined to be different with regard to their resistance to the above pathogen. Different generations (P1, P2, F1, F2, BC1, BC2) of one cross were included in the study in order to determine the values of parameters for additive and dominant gene effects and effects of two-gene epistasis. A randomized complete block design was used. Gene effects and the mode of inheritance were assessed from the analysis of generation means from a cross between two parents. Plants were artificially inoculated in the field by the toothpick method. It was found that additive genes played the most important role in the inheritance of both stem resistance to the causal agent of charcoal stem rot and wa...ter content in the internode below the ear.
