For each QTL, both additive effect and dominant effect were detected. Most QTLs had the genetic effect of partial dominance, dominance or overdominance.
Number of leaves was mainly controlled by additive effects, dominance effects were the major genetic component for length of leaves, width of leaves and area of leaves.
烤烟叶数性状主要受加性效应控制，腰叶长、腰叶宽和叶面积主要受显性效应控制。

The goodness of fit test of genetic model was significant, indicated that besides additive-dominance, other factors, such as epistasis, might affect grain plumpness.
