Innovations in Crop Seed Breeding
Abstract
The present study describes the development of a new method of the evaluation of xenogamy in crops that allows for a precise estimation of this main biological parameter without the interruption of the natural process of flowering.
The results were obtained by the growing two types of crops close to each other that differed by one feature controlled by one genome. At the same time, in some plants, this gene has to be dominant, in others, recessive. The study of the recessive offsprings and identification of plants with a dominant gene among them allowed the authors to evaluate the degree of xenogamy.
The authors developed an original scheme of grain crops breeding that allows for the preservation of the variety during the reproduction regardless of the occurring mutations and alterations of the properties by the phenotype.
The selection of plants by the results of electrophoresis allows the specialists to exclude non-typical genotypes for the creation of a nursery for the trials of the first year offsprings.
The performed studies provide an objective evaluation of xenogamy and reproduction of the grain crops during the original seed breeding.
