Fitness for vegetative and reproductive indices of T1C-19 vs. MH63 rice grown on farmland and saline-alkali soils.

			Farmland soil	Saline-alkali soil
Vegetative indices	Fitness	Plant height (cm)	0.97	0.98
		Tiller number	0.84*	0.65*
		Biomass(g)	0.87*	0.79*
	Composite fitness		0.89*	0.81*
Reproductive indices	Fitness	Effective panicle number per plant	0.79*	1.00
		Panicle length (cm)	0.96*	1.08
		Panicle weight (g)	0.94*	1.69*
		Total grain number per plant	0.89*	0.71*
		Filled grain number per plant	0.87*	3.36*
		Filled grain weight per plant (g)	0.87*	3.36*
		Thousand grain weight (g)	1.00	1.00
		Seed-setting rate (%)	0.97	4.56*
	Composite fitness		0.91*	2.10*

Fitness ratio was defined as agronomic traits of T1C-19 vs. MH63 rice; Composite fitness was defined by the average value of all fitness for vegetative traits or reproductive traits. *indicates fitness significantly more than or less than 1.00 according to t-test (p < 0.05).
