areas. Information on the inheritance of grain mould reaction is required to facilitate breeding of resistant cultivars.&#13;
The genetic control of grain mould reaction was studied in 7 crosses of 2 resistant sorghum genotypes. P1, P2, F1,&#13;
F2, BC1 and BC2 families of each cross were evaluated under sprinkler irrigation for field grade and threshed grade&#13;
scores and subjected to generation mean analysis. Frequency distributions for grain mould reaction were derived&#13;
and F2 and BC1 segregation ratios were calculated. Grain mould reaction in crosses of coloured grain sorghum was&#13;
generally controlled by two or three major genes. Resistance to grain moulds was dominant. Significant additive&#13;
gene effects were also found in all cross/season combinations. Significant dominance effects of similar magnitude&#13;
to additive effects were also observed in five out of ten cross/season combinations. Gene interactions varied according&#13;
to the parents with both resistant and susceptible parents contributing major genes. Choice of parents with&#13;
complementary resistance genes and mechanisms of resistance will be critical to the success of resistance breeding.</mods:abstract><mods:classification authority="lcc">Sorghum</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8061">2000</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>Kluwer</mods:publisher></mods:originInfo><mods:genre>Article</mods:genre></mods:mods>
