Abstract
A 2-yr study was conducted to investigate additive, dominance, and epistatic gene effects for weather fleck in Maryland tobacco (N. tabacum L.). P1, P2, F1, F2, P1F1, and P2F1 population means from each of 7 crosses were used to estimate gene effects. In general, additive gene effects were more important in the inheritance of weather fleck than domiannce or epistatic effects; however, in 3 of the 7 crosses dominance and (or) epistatic gene effects were important. Adequate additive gene effects were present in 5 of the 7 crosses to allow considerable progress towards selection of more weather fleck resistant lines. In 2 families, because of significant epistatic gene effects, the development of weather flock resistant lines could be accomplished by producing doubled haploids from desirable F1 plants or by using a reciprocal of recurrent selection program.
