Title

Evaluation of rice grain yield and yield components of Nona Bokra chromosome segment substitution lines with the genetic background of Koshihikari, in a saline paddy field

Shiro Mitsuya; Norifumi Murakami; Tadashi Sato; et al. AoB Plants 2019. doi:10.1093/aobpla/plz040

Other claims from this paper (8)

Intervention effect Salinity decreased grain yield across CSSLs and Koshihikari.
Intervention effect Salinity decreased yield components other than panicle number.
Association SL538 had higher grain yield SEI than Koshihikari under salinity in both experiments.
Observation SL538 retained grain filling and harvest index.
Mechanism Maintenance of Na+, Cl− and K+ homeostasis did not explain SL538 performance.
Association Other CSSLs had greater grain weight SEI than Koshihikari under salinity.
Mechanism Greater grain weight SEI might relate to low Na+ concentration in leaves and panicles.
