Comparison of phenotypes after high-temperature treatment in rice at the booting stage. The Cheongcheong/Nagdong double haploid (CNDH) 120 line was treated with a high temperature during the booting stage. The phenotype that appeared after the booting stage was assessed. (A) Nagdong is a variety that is tolerant to high temperatures; (B) Cheongcheong is a variety that is susceptible to high temperatures. Culm length decreased and no heading was observed; (C) CNDH11 exhibited a decrease in tiller number after the high-temperature treatment and did not show heading; (D) CNDH109 exhibited a great decrease in tiller number after treatment with high temperature.
