Genetic Aspects of Photosynthesis of Aromatic Tobacco Varieties and Optimization Ways of Selection: Rate of Photosynthesis
Keywords:
табак, интенсивность фотосинтеза, комбинационная способность, диаллельный анализ, корреляции, селекцияAbstract
In the first article of the presented series results of diallel analysis of seven tobacco varieties of “Samsun” species have been introduced which have proved that the genetic factor in the rate of photosynthesis is largely influenced by the effect of additive genes, which have demonstrated recessive character against the variety with high indices.
Related to the existence of positive, high genetic correlation between the mentioned property and size and quantity of leaves, the abovementioned features have been observed as a means of identification of perspective genotypes endowed with high index of photosynthesis rate in the older hybrid generations. The research outcomes have indicated
the specific ways for optimal selection of aromatic tobacco varieties.
