摘要
Sugarcane is a major food and bioenergy crop globally.It pro-duces~80%of sugar consumed worldwide,with Brazil and India together accounting for 61%of world sugarcane produc-tion in 2021[1].Globally,sugarcane is the 5th largest crop by production value and acreage,and it is also the second largest bioenergy crop[1,2].Modern sugarcane is an interspecific hybrid(Saccharum species hybrid)of wild progenitor species Saccharum officinarum(2n=80;x=10)andSaccharumspon-taneum(2n=40 to 130;x=8)[3].This genetically complex polyploid crop with varied chromosome numbers(100 to 130)has one of the largest genomes(~10 kb)among plants,making sugarcane breeding considerably slow and challenging.
