Abstract

In order to study the genetic control of resistance to COMMON SMUT in MAIZE, two resistant inbred lines, K1264/1 and K47/2-2-21 and two susceptible inbred lines, K3304/1-2 and K47/2-2-1-3-3-1, were crossed as K1264/1 × K3304/1-2, K47//2-2-21 × K3304/1-2 and K1264/1 × K47/2-2-1-3-3-1. The F1, F2, BC1 and BC2 progenies were produced and evaluated along with parents using randomized compelet block design with three replications. All generations were artificially inoculated with spordia of Ustilago maydis suspension. Inoculation was carried out 7-10 days after silking through injection of 3 ml of 106 spores/ml fungal suspension, using tip injection method. At maturity, disease severity was determined based on ears infection and analysed according to GENERATION MEANS ANALYSIS method for three crosses. Joint scaling test showed that the presence of ADDITIVE, DOMINANCE and EPISTASIS effects, especially ADDITIVE × ADDITIVE and DOMINANCE × DOMINANCE type, and in lesser extent, ADDITIVE × DOMINANCE, in genetic control of resistance to MAIZE COMMON SMUT. Average broad and narrow-sense heritability based on three crosses data were estimated 80.3 and 57.3, respectively.
