Novel Genes and Genetic Loci Associated With Root Morphological Traits, Phosphorus-Acquisition Efficiency and Phosphorus-Use Efficiency in Chickpea

Chickpea—the second most important grain legume worldwide—is cultivated mainly on marginal soils. Phosphorus (P) deficiency often restricts chickpea yields. Understanding the genetics of traits encoding P-acquisition efficiency and P-use will help develop strategies to reduce P-fertilizer application. A genome-wide association mapping approach was used determine loci genes associated with root architecture, efficiency, any proxy traits. Using three statistical models—a generalized linear model (GLM), a mixed (MLM), fixed random circulating probability unification (FarmCPU) —10, 51, 40 marker-trait associations (MTAs), respectively were identified. single nucleotide polymorphism (SNP) locus (Ca1_12310101) Ca1 traits, i.e., physiological shoot dry weight, P content Genes related concentration (NAD kinase 2, dynamin-related protein 1C), (fasciclin-like arabinogalactan protein), specific length (4-coumarate–CoA ligase 1) manganese in mature leaves (ABC1 family protein) The MTAs novel identified this study can be improve chickpea.
