The high protein value, essential minerals, dietary fibre and notable ability to fix atmospheric nitrogen make chickpea a highly remunerative crop, particularly in low-input food production systems. Of the variety of constraints challenging chickpea productivity worldwide, salinity remains of prime concern owing to the intrinsic sensitivity of the crop. In view of the projected expansion of chickpea into arable and salt-stressed land by 2050, increasing attention is being placed on improving the salt tolerance of this crop. Considerable effort is currently underway to address salinity stress and substantial breeding progress is being made despite the seemingly highly-complex and environment-dependent nature of the tolerance trait.
This review aims to provide a holistic view of recent advances in breeding chickpea for salt tolerance. Initially, we focus on the identification of novel genetic resources for salt tolerance via extensive germplasm screening. We then expand on the use of genome-wide and cost-effective techniques to gain new insights into the genetic control of salt tolerance, including the responsive genes/QTL(s), gene(s) networks/cross talk and intricate signalling cascades.
鹰嘴豆蛋白质含量高、富含必需矿物质、膳食纤维且具有显著的固氮能力,使其成为一种高收益作物,在低投入粮食生产系统中尤为如此。在全球范围内挑战鹰嘴豆生产力的各种限制因素中,由于该作物的内在敏感性,盐度仍然是首要关注的问题。鉴于预计到2050年鹰嘴豆将扩展到可耕地和盐胁迫土地,人们越来越关注提高这种作物的耐盐性。目前正在付出巨大努力来应对盐胁迫,尽管耐盐性性状看似高度复杂且依赖环境,但仍取得了显著的育种进展。
本综述旨在全面介绍鹰嘴豆耐盐性育种的最新进展。首先,我们专注于通过广泛的种质筛选来鉴定耐盐性的新遗传资源。然后,我们详细阐述如何利用全基因组和具有成本效益的技术来深入了解耐盐性的遗传控制,包括响应基因/数量性状位点、基因网络/相互作用以及复杂的信号级联反应。
