Chlorophyll fluorescence analysis in diverse rice varieties reveals the positive correlation between the seedlings salt tolerance and photosynthetic efficiency

Table 1 The eight accessions used in the pilot experiment

ID	Name	Country of origin	Subspecies	Injury score^b	Salinity tolerance level^c
8777	Munao PS405	Philippines	Indica	7.86	S
IR28	IR28	Philippines	Indica	5.2	M to S
IR64	IR64	Philippines	Indica	5.12	M to S
223	Priano Guaira	Brazil	Japonica	5	M
Nona Bokra	Nona Bokra	India	Indica	2.1	M to T
149	Sinaguing	Philippines	Japonica	2	M to T
245^a	Sab Ini	Egypt	Japonica	1.57	M to T
IR66946	FL478	Philippines	Indica	1	T

^aVariety 245 was excluded from discussion due to its erratic behavior; it is likely that the tested samples were contaminated
^bThe injury score was the average of three replicates
^cSalinity tolerance level was assigned to five classes based on the injury score. M Moderate (Injury score = 5), S Sensitive (Injury score > = 7), T Tolerant (Injury score = 1)
