“…The parallel crossing of a recurrent parent with donor parents and intercrossing F 1 s followed by backcross with a recurrent parent is a promising way of combine multiple traits. This scheme was utilized in combining traits like bacterial leaf blight (BLB) and lepidopteran insect pest tolerance in rice (Jiang et al, 2004), BLB in rice (Shanti et al, 2010), wheat stripe rust and leaf rust resistance genes (Santra et al, 2006;Yadawad et al, 2017), barley leaf rust, net blotch and spot blotch resistance (Hickey et al, 2017). This is the most reliable method as it reduces the time period to combine genes/QTLs and assures the fixation of genes/QTLs (Joshi and Nayak, 2010).…”

“…Kolekar et al (2017) observed more recovery of resistant progenies for rust over the LLS, especially when the target trait is controlled by a combination of large and small effect QTLs. A strategy of single backcrossing has been successfully used to introgress rust-resistant genes in wheat (Wang et al, 2009;Yadawad et al, 2017), leaf rust, net blotch, and spot blotch resistance in barley (Hickey et al, 2017), and LLS and rust resistance in groundnut (Kolekar et al, 2017). These studies indicated that one to two cycles of backcross is sufficient in improving elite cultivars while transferring the desired genes from an adapted donor parent.…”

“…Meanwhile, another nine polymorphic SSR and EST-SSR markers reported to be related to other putative protein functions and unknown functions were located on LGs 1, 2, 4 and 5 (Isemura et al ., 2012; Chen et al ., 2015). The number of polymorphic SSR and EST-SSR markers obtained from this study may be lower than those in other studies, which have reported using 26–241 polymorphic loci for background selection (Divya et al ., 2014; Miah et al ., 2015; Pradhan et al ., 2015; Ahmed et al ., 2016; Arunakumari et al ., 2016; Xiao et al ., 2016; Krishna et al ., 2017; Yadawad et al ., 2017; Baliyan et al ., 2018; Jamaloddin et al ., 2020; Kumar et al ., 2021). These results may be due to the number of markers and genetic variation of the parents used.…”

“…In wheat, during last two decades, more than 50 genes have been suggested for MAS, for diseases including powdery mildew, leaf rust, stem rust, stripe rust, cereal cyst nematode, hessian fly, wheat streak mosaic virus etc ( Gupta et al, 2010 ; Dreisigacker et al, 2016 ). As a result, several molecular breeding lines have been developed with enhanced resistance to cereal cyst nematode resistance ( Barloy et al, 2007 ), Fusarium head blight ( Miedaner et al, 2009 ; Salameh et al, 2011 ), leaf rust ( Nocente et al, 2007 ; Kumar et al, 2010 ; Yadawad et al, 2017 ; Randhawa et al, 2019 ), stem rust ( Niu et al, 2011 ; Klindworth et al, 2012 ; Yadav et al, 2015 ), spot blotch ( Vasistha et al, 2016 ), and others. Barley yellow mosaic virus disease resistance through molecular breeding has been a target in barley in Europe ( Werner et al, 2005 ).…”
