| Abstract: | According to 8 F1 materials of purple sheath inbred lines×green sheath DH lines of maize, 607 DH lines were induced by hybridization and doubled by self-pollination in Hainan province. The suitability of purple sheath DH lines and green sheath DH lines, pollution rate, average number of polluted plants, and the number of polluted plants by purple sheath and green sheath in green sheath DH lines were tested and analyzed. The results showed that the pollen viability of haploid with purple leaf sheath was stronger than that of haploid with green leaf sheath. |

| Keywords: | Maize Purple sheath Green sheath Doubled haploid Pollen viability |
