Table 4.

Grain setting rate of the four rice varieties under the two weather scenarios.

Variety	Grain setting rate (%)
	LHS	NWS
Mianhui101	65.4 ± 5.1c**	80.9 ± 10.4b
IR64	66.3 ± 10.1c**	85.9 ± 3.7a
Quanliangyou681	80.9 ± 7.4a*	88.8 ± 2.9a
SDWG005	74.3 ± 9.8b	77.7 ± 8.9c

** and * indicate significant differences at P<0.01 and P<0.05, respectively, between a variety in the long-term heat scenario (LHS) and the same variety under the normal weather scenario (NWS).

Different lowercase letters indicate significant differences between varieties under the same weather scenario at the 5% level using Tukey’s test (n=20).
