摘要
以国内外近20年来80余篇参考文献为基础,从抗旱小麦品种演变,抗旱节水生理遗传育种机理的历史和最新研究进展,包括抗旱性和节水性的生理生化机制以及抗旱节水遗传等方面,对小麦抗旱节水生理遗传育种的研究进展做了综述。认为随着小麦抗旱高产育种研究的不断深入,旱地育种研究逐渐从抗旱性生理遗传育种研究发展到现在的抗旱节水性生理遗传育种研究,通过育种手段提高小麦水分利用效率成为节水农业一个重要研究方向。
Examining and referring to more than eighty papers published in recent twenty years, the paper summarizes the advances in drought-resistance and water-saving physiology, genetics and breeding of wheat in terms of cultivar alternations, water-resistance and water-saving genetic and physiological mechanisms, and the latest research achievements, especially water-resistance and water-saving physiological and biochemical mechanisms, and points out that as drought-resistance and high-yield wheat breeding develops forward, its research focuses have been moving from the researches dealing with drought-resistance physiological genetics to the current ones dealing with water-resistance and water-saving genetics, and that improving water use efficiency of wheat by breeding measures has been becoming an important research field in water-saving farming.
