METHOD OF SELECTION OF COLD RESISTANT CORN GENOTYPES Russian patent published in 1995 - IPC

Abstract RU 2045890 C1

FIELD: agriculture. SUBSTANCE: selection is carried out by pollen collection, effect with 0.005 M benzidine solution in acetate buffer, pH 4.7. Mixture is kept for 5-10 min, 0.01% solution of hydrogen peroxide is added, and resistance to cold of genotypes is determined by color change intensity for 20-60 s. Colorless is typical for cold resistant genotypes (0-1 point), light blue and blue for mean resistant genotypes (2-3 points) and dark blue for nonresistant to cold genotypes (4-6 points). EFFECT: improved method of corn selection. 1 tbl, 1 dwg
