METHOD FOR CREATING OF ISOGENIC LINE BY DOMINANT FEATURE OF PLANT SEED Russian patent published in 2007 - IPC A01H1/04 

FIELD: agriculture, in particular, selection and genetics of cultivated crops such as sunflower.

SUBSTANCE: method involves providing continuous back-crossing pattern and establishing genotype of back-crossing plants of each back-crossing plant generation on the basis of biochemical analysis results, in particular, from fatty-acid composition of oil of apical part of sprout cotyledon; separating apical part of cotyledon from sprout during the first two days after emergence of crops under field conditions; separating heterozygous sprouts; growing sprouts in the field to produce reproductive plants; crossing said plants as paternal form with recipient for producing of the following back-crossing generation.

EFFECT: provision for producing of heterozygous genotypes of back-crossing plants at early stage of emergence of crops under field conditions, retention of sprouts vitality under analysis, reduced labor intensity in creating of isogenic lines by eliminating seedling method for plant growing.
