Genome-wide association studies of grain quality traits in maize

Abstract: High quality is the main goal of today’s maize breeding and the investigation of grain quality traits would help to breed high-quality varieties in maize. In this study, genome-wide association studies in a set of 248 diverse inbred lines were performed with 83,057 single nucleotide polymorphisms (SNPs), and five grain quality traits were investigated in diverse environments for two years. The results showed that maize inbred lines showed substantial natural variations of grain quality and these traits showed … Show more

“…The observed relationship between grain yield and quality traits in this research under both optimal and low N conditions imply that selecting for grain yield alone will not increase protein, starch, or oil content. On the other hand, protein content had a significant negative correlation with starch content in all populations, which is consistent with previous results (Liu et al 2008;Zheng et al 2021). Thus, to increase grain quality, particularly under low N stress, there is a need to select for both grain yield and grain quality.…”

“…Candidate genes and SNPs discovered by GWAS for maize grain nutrient content can provide critical information for maize breeding efforts focusing on developing highquality varieties (Zheng et al 2021). In this study, GWAS identified 42 SNPs linked to the grain quality traits studied under low N conditions.…”

“…Genome-wide association analysis, based on millions of molecular markers, is currently widely used in the analysis of complex quality traits for crops such as wheat (Yang et al, 2021 ), maize (Zheng et al, 2021 ), pea (Gali et al, 2019 ), soybean (Shook et al, 2021 ), flaxseed (Soto-Cerda et al, 2018 ), and Brassica (Xiao et al, 2019 ). Many reports addressed use of GWAS for the identification of candidate genes associated oil content (Pal et al, 2021 ), fatty acids (Tang et al, 2019 ), glucosinolate (Qu et al, 2015 ), and fiber fractions (Gajardo et al, 2015 ; Körber et al, 2016 ) in B. napus .…”

“…Genome-wide association study (GWAS) is a powerful tool for gene mapping in plants and animals, and has been widely used for genetic dissection of complex quantitative traits in many major crop species ( Xiao et al , 2017 ; Liu and Yan, 2019 ; Cortes et al , 2021 ). In maize, GWAS has been successfully employed to understand the genetic basis of, and to identify candidate genes related to, flowering time and plant height ( Vanous et al , 2018 ; Li et al , 2020 ; Zheng et al , 2021a ), stalk traits ( Zhang et al , 2018 ; Mazaheri et al , 2019 ), tassel architecture ( Wu et al , 2016 ; Y. Wang et al , 2019 ), nitrogen use efficiency ( Morosini et al , 2017 ; Ertiro et al , 2020 ), low-phosphorus tolerance ( Xu et al , 2018 ; Q. J. Wang et al , 2019 ), cold tolerance ( Yi et al , 2021 ), drought tolerance ( Zaidi et al , 2016 ; Yuan et al , 2019 ; Liu and Qin, 2021 ), grain yield and yield-related traits ( Zhang et al , 2020a ; Yang et al , 2020 ; Ma and Cao, 2021 ), and grain quality ( Zhang et al , 2020b ; Zheng et al , 2021b ; Zhou et al , 2021 ). Moreover, several candidate genes involved in genetic control of root-related traits have been identified in maize by a GWAS approach.…”
