Heat resistance during heading-flowering was evaluated with 40 high quality rice combinations under high temperature conditions in phytotron. Heat tolerance of rice varieties was evaluated using seed setting rate and relative seed setting rate under high temperature. The result showed that, there are significant differences in heat tolerance and yield potential among varieties, N22, Huanghuazhan, HQ 5, Gui 1025, Guanghui 998 and Jinxiangnuo are heat tolerant combinations; Yuejingsimiao 2, SH14, Liyuanzhan 2, Liushayouzhan 202 and Yuguizhan are semi-heat tolerant combinations; OM4900、882H、93-11 and the others are heat sensitive combinations.
Key words: rice; heat resistant property; evaluation
