Dataset of rice growth for saline-alkaline tolerance screening

This dataset exhibits the growth profile of multiple rice varieties, most of which include world or Japanese rice core collections, under saline-alkaline conditions through two screenings. In both the first and second screenings, the rice plants were hydroponically cultivated for 4 weeks under normal conditions and then subjected to control or saline-alkaline conditions for 2 weeks. In the first screening, dry weight, dry weight ratio, and SPAD values were measured, and candidate varieties possessing saline-alkaline tolerance (7 varieties) or sensitivity (3 varieties) were selected based on the dry weight ratio. In the second screening, the fresh/dry weight, fresh/dry weight ratio, length of roots and shoots, and chlorophylls were measured in totally 12 rice varieties. These include the 7 tolerant and 3 sensitive varieties identified in the first screening, as well as 1 known saline-tolerant and 1 saline-sensitive variety. The dataset is expected to be useful for understanding the differences in saline-alkaline tolerance in multiple rice varieties and for breeding new saline-alkaline tolerance rice cultivars.
