  1. DS2011RS: RS experiment of dry season at IRRI; WS2011RS: RS experiment of wet season in Nepal; WS2011NS: NS experiment of wet season in Nepal; GY: Grain yield; DTF: Days to 50% flowering; PHT: Plant height; LR: Leaf rolling; BIO: Biomass; HI: Harvest index; PAN: Panicle number; NF: Did not flower; LR, BIO, HI and PAN were measured in WS2011RS only.
