摘　　要：利用可控温室对杂交中籼品种——皖稻153耐高温特性进行了研究,结果表明,在抽穗扬花期遇持续高温条件下,皖稻153的结实率仍达66%以上,明显高于高温敏感品种,且达极显著水平;每穗总粒数、每穗实粒数、千粒重等经济指标也与高温敏感品种达极显著水平。由此可知,皖稻153具有较强的耐高温特性。This paper was to research on the high temperature resistance of WD153 by used controllable greenhouse. The result showed that seed setting rate of WD153 was over 66% under high temperature in the heading flowering period, and was obviously higher than heat sensitive variety. Economic index of grain number per panicle ,filled grain number per panicle and 1000 -grain weight were higher than heat sensitive variety, and the difference was very significant. Therefore ,WD153 shows stronger high temperature tolerance.
