“…This software has been used extensively to study autohexaploid sweet potatoes for root-knot nematode resistance ( Oloka et al, 2021 ), carotenoid, and starch biosynthesis ( Gemenet et al, 2020 ) and yield component traits ( da Silva Pereira et al, 2020 ). Several autotetraploid rose maps have been constructed using polymapR ( Bourke et al, 2017b ; Zurn et al, 2018 , 2020 ; Cheng et al, 2021 ; Yu et al, 2021 ) and QTL for stem prickles and flavonoid and carotenoid levels using polyqtlR ( Bourke et al, 2021 ; Cheng et al, 2021 ). Interconnected population QTL analysis has been performed in autotetraploid potatoes using diaQTL analyzing tuber shape ( Amadeu et al, 2021 ).…”
