Genetic Nature of the “Hanthoviresens” Mutation of l - 4 Yellow Line—Transforming into Green and Their Relationship with the Chlorophylls Content

Abstract

It was determined that the yellow colour of Hanthoviresens mutation in L4 line of leaves is the result of genetic transforming into green and correlation of their hybrids on the L3. The yellow color in the leaves of L4 line is the result of recessive mutation relatively to anthocyanin colour in L3 line. This mutation and chlorophylls quantity in L4 line are being controlled by nuclear genes and high quantity of chlorophylls in L3 line is the result of linkage in gene group where gene Rstv is located or the result of the effect of pleiotropia on chlorophylls content. That is why chlorophylls quantity in plants with yellow colour is lower than in L3 line as these plants resulted from expression of r p r p r_st<sup style="margin-left:-6px;">v</sup> r_st<sup style="margin-left:-6px;">v</sup> gene type.
