L. is the third greatest widely planted imperative pulse crop worldwide, and it belongs to the Leguminosae family. Drought is the utmost common abiotic factor on plants, distressing their water status and limiting their growth and development. Chickpea genotypes have the natural ability to fight drought stress using certain strategies viz., escape, avoidance and tolerance. Assorted breeding methods, including hybridization, mutation, and marker-aided breeding, genome sequencing along with omics approaches, could be used to improve the chickpea germplasm lines(s) against drought stress. Root features, for instance depth and root biomass, have been recognized as the greatest beneficial morphological factors for managing terminal drought tolerance in the chickpea. Marker-aided selection, for example, is a genomics-assisted breeding (GAB) strategy that can considerably increase crop breeding accuracy and competence. These breeding technologies, notably marker-assisted breeding, omics, and plant physiology knowledge, underlined the importance of chickpea breeding and can be used in future crop improvement programmes to generate drought-tolerant cultivars(s).
鹰嘴豆是世界上第三大广泛种植的重要豆类作物,属于豆科。干旱是影响植物的最常见非生物因素,会影响其水分状况并限制其生长发育。鹰嘴豆基因型具有利用某些策略(即逃避、避旱和耐旱)对抗干旱胁迫的天然能力。包括杂交、诱变和分子标记辅助育种在内的各种育种方法,以及基因组测序和组学方法,可用于改良鹰嘴豆种质系以抵御干旱胁迫。根系特征,例如深度和根生物量,已被认为是鹰嘴豆应对终期干旱耐受性最有益的形态学因素。例如,分子标记辅助选择是一种基因组辅助育种(GAB)策略,可以显著提高作物育种的准确性和效率。这些育种技术,特别是分子标记辅助育种、组学和植物生理学知识,凸显了鹰嘴豆育种的重要性,可用于未来的作物改良计划,以培育耐旱品种。
