A Meta-Analysis of Quantitative Trait Loci Associated with Stay-Green in Sorghum

Abstract: A strong association between stay-green and post-flowering drought tolerance in sorghum has been established previously. In this study, a meta-analysis was conducted to find relevant genetic intervals that regulate stay-green in sorghum and thereby affect drought resilience. Meta-QTL analysis was performed to combine 115 QTLs mapped in previous studies and locate regions where recurrent QTLs occurred across experiments. This approach overcomes the constraints of a single QTL association experiment by increasin… Show more

“…Meta‐analysis has been performed for a number of traits in a wide range of species, including wheat, rice, maize, sorghum, barley, and tomato (Aquib & Nafis, 2022; Ayenan et al., 2018; Kaur et al., 2021; Saini, Srivastava, et al., 2022; Sandhu et al., 2021; Zhang et al., 2017). However, there are no studies available on the meta‐analysis of QTLs in pigeonpea.…”

“…Meta‐analysis can be performed using either MQTL or BioMercator software by formulating and inserting particular sets of algorithms for accurate estimation and recalculation of the genetic position for a specified set of QTLs (Wang et al., 2014). The MQTL analysis has already been conducted in different crops, including wheat (e.g., Gudi, Saini, et al., 2022; Kumar et al., 2021; Pal et al., 2021, 2022; Saini et al., 2021; Saini, Chahal, et al., 2022; Saini, Srivastava, et al., 2022; Tanin et al., 2022), rice (e.g., Sandhu et al., 2021), maize (e.g., Kaur et al., 2021), sorghum (e.g., Aquib & Nafis, 2022), barley (e.g., Zhang et al., 2017), and tomato (e.g., Ayenan et al., 2018). Furthermore, MQTL analysis has also been conducted in some legume crops for different traits such as Fe and Zn content and resistance to white mold in French beans (Izquierdo et al., 2018; Vasconcellos et al., 2017), yield‐related traits, seed protein content and partial resistance to Aphanomyces root rot in pea (Hamon et al., 2013; Klein et al., 2020), leaf spot resistance, plant height, seed number, and seed yield in peanut (Chen et al., 2019; Lu et al., 2018; Lv et al., 2018), and—quality traits in soybean (Chen et al., 2021).…”

“…The generation of superior lines with enhanced resilience to abiotic stress using molecular breeding procedures has a limited track record of success (Tonapi et al, 2020). Due to its significance, several QTL mapping work for stay green in sorghum have been documented (Table 8) (Kiranmayee et al, 2015;Aquib and Nafis, 2022). So far, 7 stay green trait source have been exploited to identify QTLs for this phenotype.…”
