Abstract

Background: Being a vital source of high-quality dietary protein, chickpea is an unavoidable legume. The present investigation was performed to study the applicability of the microsatellite markers linked with drought tolerance in Indian chickpea genotypes collected from different genetic background. Methods: In Rabi 2021-22, forty chickpea genotypes including national check for drought tolerance, elite cultivars, released varieties and advanced breeding lines were screened employing forty microsatellite markers linked with drought tolerance associated traits. Result: Among forty drought tolerance related microsatellite markers, twenty-six were found to be polymorphic and produced a total of 66 alleles, with a mean of 2.5 alleles per locus. Model-based population structure analysis clearly distinguished the drought tolerant genotypes including ICC4958, JG74, JAKI9218, JG16, JG6, JG14 and JG11. The principle coordinate analysis (PCoA) and analysis of molecular variance (AMOVA) further confirmed these results. Findings of the present investigation would have a greater potential for further utilization in breeding of drought specific chickpea cultivar(s).

鹰嘴豆抗旱相关性状微卫星标记的优选

背景:鹰嘴豆是一种不可避免的豆类，是优质膳食蛋白质的重要来源。本研究旨在研究来自不同遗传背景的印度鹰嘴豆基因型抗旱性相关微卫星标记的适用性。方法:利用40个与抗旱相关性状相关的微卫星标记，对Rabi 2021-22品种中鹰嘴豆国家耐旱检查、优良品种、发布品种和先进选育品系等40个鹰嘴豆基因型进行筛选。结果:在40个抗旱相关微卫星标记中，发现26个具有多态性，共产生66个等位基因，平均每个位点2.5个等位基因。基于模型的群体结构分析明确了抗旱基因型为ICC4958、JG74、JAKI9218、JG16、JG6、JG14和JG11。主坐标分析(PCoA)和分子方差分析(AMOVA)进一步证实了这些结果。本研究的结果将在干旱鹰嘴豆品种的选育中具有更大的应用潜力。
