The ever-rising population of the twenty-first century together with the prevailing challenges, such as deteriorating quality of arable land and water, has placed a big challenge for plant breeders to satisfy human needs for food under erratic weather patterns. Rice, wheat, and maize are the major staple crops consumed globally. Drought, waterlogging, heat, salinity, and mineral toxicity are the key abiotic stresses drastically affecting crop yield. Conventional plant breeding approaches towards abiotic stress tolerance have gained success to limited extent, due to the complex (multigenic) nature of these stresses. Progress in breeding climate-resilient crop plants has gained momentum in the last decade, due to improved understanding of the physiochemical and molecular basis of various stresses. A good number of genes have been characterized for adaptation to various stresses. In the era of novel molecular markers, mapping of QTLs has emerged as viable solution for breeding crops tolerant to abiotic stresses. Therefore, molecular breeding-based development and deployment of high-yielding climate-resilient crop cultivars together with climate-smart agricultural practices can pave the path to enhanced crop yields for smallholder farmers in areas vulnerable to the climate change. Advances in fine mapping and expression studies integrated with cheaper prices offer new avenues for the plant breeders engaged in climate-resilient plant breeding, and thereby, hope persists to ensure food security in the era of climate change.

QTLian谷物气候适应力育种:进展与前景。

二十一世纪人口的不断增长,以及诸如耕地和水质不断恶化等挑战,对植物育种者如何在不稳定的天气条件下满足人类对粮食的需求提出了巨大的挑战。稻米,小麦和玉米是全球消费的主要主粮。干旱,涝灾,高温,盐碱化和矿物毒性是严重影响作物产量的关键非生物胁迫。由于这些胁迫的复杂(多基因)性质,常规的植物育种方法在非生物胁迫耐受性方面取得了有限的成功。在过去的十年中,由于人们对各种胁迫的物理化学和分子基础有了更好的了解,因此在具有气候适应能力的农作物育种方面取得了进步。已经描述了许多基因可以适应各种压力。在新型分子标记时代,对QTL进行定位已经成为育种对非生物胁迫具有耐受性的作物的可行解决方案。因此,基于分子育种的高产耐气候作物品种的开发和部署,以及气候智能型农业实践,可为易受气候变化影响的地区的小农提供增产途径。精细制图和表达研究的进步与更便宜的价格相结合,为从事具有气候适应性的植物育种的植物育种者提供了新的途径,因此,在气候变化时代,仍然存在确保粮食安全的希望。QTL的作图已经成为育种耐受非生物胁迫的作物的可行解决方案。因此,基于分子育种的高产耐气候作物品种的开发和部署,以及气候智能型农业实践,可为易受气候变化影响的地区的小农提供增产途径。精细制图和表达研究的进步与更便宜的价格相结合,为从事具有气候适应性的植物育种的植物育种者提供了新的途径,因此,在气候变化时代,仍然存在确保粮食安全的希望。QTL的作图已经成为育种耐受非生物胁迫的作物的可行解决方案。因此,基于分子育种的高产耐气候作物品种的开发和部署,以及气候智能型农业实践,可为易受气候变化影响的地区的小农提供增产途径。精细制图和表达研究的进展与更便宜的价格相结合,为从事具有气候适应性的植物育种的植物育种者提供了新的途径,因此,在气候变化时代,仍然存在确保粮食安全的希望。基于分子育种的高产耐气候作物品种的开发和部署,以及气候智能型农业实践,可为易受气候变化影响的地区的小农提供增产途径。精细制图和表达研究的进步与更便宜的价格相结合,为从事具有气候适应性的植物育种的植物育种者提供了新的途径,因此,在气候变化时代,仍然存在确保粮食安全的希望。基于分子育种的高产耐气候作物品种的开发和部署,以及气候智能型农业实践,可为易受气候变化影响的地区的小农提供增产途径。精细制图和表达研究的进步与更便宜的价格相结合,为从事具有气候适应性的植物育种的植物育种者提供了新的途径,因此,在气候变化时代,仍然存在确保粮食安全的希望。
