The Genetics of Anthocyanin Pigmentation (of Colour) and Chlorophylls Content of G. hirsutum L. Cotton Plant
Abstract:

In the article, the first time genes of anthocyanin pigmentation Rp and Rstv appeared in cotton plant interacting complementarily. Recessive homozygosis rprрrstvrstv conditions the development of green colour. The gen Rp conditions the development of anthocyanin in all organs of plants, Rstv only exists on the stalk and in the nerves of leaves, the flower is uncolored, the boll is green. The plants’ existence in genotype of both dominant equilocal genes (Rp, Rst) provides a high rate of biosynthesis of anthocyanindark red. Inheritance of the chlorophylls “a” + b” and “a” and “b” quantity in anthocyanin coloured L-2 and L-3 lines of F1 and F2 generations. The quantity of chlorophylls in anthocyanin coloured L-3 line was defined 1.0 - 1.5 times higher and participation of the gen Rstv responsible for anthocyanin colour in chlorophylls biosynthesis was also defined. Apparently, in the line L-3 in Rstv is localized, there are gens which are responsible for the quantity of chlorophyll or Rstv has pleiotropic effects on the quantity of chlorophyll. It is proved with low quantity of chlorophyll in green coloured plants by recessive homozygote condition rprprstvrstv green colour.
