Inheritance of quantitative characteristics from parental pairs in their progeny is conditioned by
various effective factors presenting a group of genes (polygenes), the effect of which is estimated
by diallel analysis. Investigations of quantitative characters (stalk height, leaf number per stalk
and green yield per stalk), were made on four parental genotypes of tobacco: Burley - B-2,
Suhum - S-1 with pink flower, Suhum S-2 with white flower and Prilep - P-84-FR with red
flower and their six diallel F1 hybrids. Crossings were made in 2006 and the final trial was set in
2007, on the field of Tobacco Institute-Prilep, in a randomized block design with four
replications. The aim of our investigations was to determine the level of inheritance of
measurable characters through assessment of the effective factors: number of genes (k) and their additive (d) and dominant (h) effects, which will be a significant contribution to the
quantitative genetics of tobacco. Analyses and assessments were based on the methods and
mathematical models of B. I. Hayman, K. Mather and J.L. Jinks.
In all combinations, the additive effect was higher than the dominant one (d>h), implying that
inheritance of quantitative characters is created mainly by the additive genes. Values for the
effective factors are very low and insufficient to make their estimation. The highest grade
for additive genes strength in the inheritance of stalk height was recorded in the Burley (B-2),
and for the strength of dominant genes in Suhum (S-1 and S-2). The strongest effect of additive
genes for the characters: number of leaves and green mass yield per stalk was recorded in
Suhum (S-1 and S-2). Results presented in the paper are of a great interest for tobacco breeding
(Nicotiana tabacum L.), and the methods are applicable for many other cultures.
