Genetic Aspects of Photosynthesis of Aromatic Tobacco Varieties and the Ways of Selection Optimization: the Content of Green Pigments

Abstract

The results of diallel analysis of seven varieties of Samsun tobacco have been summed up in the second article of the presented series. The data testify that the green pigment content is largely affected by the impact of additive genes, which have demonstrated dominant characteristics in the high index varieties. Due to the positive high genetic correlations between the
green pigment content and dry leaf yield, leaf formation rate and their number, the plant blossoming period and its height, the mentioned properties have been observed as a means of identification of perspective genotypes with high index of green pigment content in the elder hybrid generations. Specific pathways of selection optimization for aromatic varieties have been also recommended.
