“…Polyploid plants often exhibit commercially beneficial qualities, e.g., increased vigour, improved product quality, enlarged organs, enhanced tolerance to both biotic and abiotic stresses and increased heterozygosity and heterosis, in contrast to their diploid relatives ( Sattler, Carvalho & Clarindo, 2016 ; Liu & Sun, 2019 ). Polyploidy often results in downregulated fertility because the expression of fertility-related genes is lower than that of compared to their diploid relatives ( Li et al, 2019 ). Developing polyploidy in plants has been the focus of many plant breeders for some time ( Huang, Li & Cong, 1990 ; Bancroft et al, 2011 ; Rambani, Page & Udall, 2014 ; Li et al, 2019 ; Shenton et al, 2020 ).…”
