The study on kenaf sterile line may be a base for the utilization of heterosis. In this paper, the research progress of kenaf sterile line was summarized based on the level of morphology, cell and molecule. We also discussed some related technological problems of heterosis.

红麻雄性不育系的研究是红麻杂种优势利用的重要基础，本文从个体形态、细胞和分子生物学层面上综述红麻雄性不育系的研究进展，并讨论和展望了红麻雄性不育与杂种优势利用的关键科学技术问题。

With and without the assistance of one water, ammonia, and methanol molecule, the proton-transfer tautomerisms of 2-hydroxylpyridine are investigated systematically employing the B3LYP/6-311++G** level of theory. Both the keto and hydroxyl form of 2-hydroxylpyridine can exist stably though the keto form is slightly more stable than that of hydroxyl form.
