Light condition during grain-filling stage of main crop strongly influences ratooning ability of low-stubble ratoon rice

Crop and Environment
Compared with high-stubble ratoon rice (RR), low-stubble RR is superior in yield potential, grain quality, and economic benefit. However, the unstable ratooning ability limits the grain yield of low-stubble RR production. Light condition during the grain-
