| 摘 要： | 本文对3个元阳县哈尼族人持续种植了上百年的水稻品种和3个现代品种分别种植在元阳梯田6个不同海拔梯度进行主要农艺性状比较研究。研究结果表明：传统品种在不同海拔的株高、穗长、有效穗等农艺性状差异不显著,而现代品种在不同海拔的农艺性状波动较大,这可能是元阳地方水稻品种长期种植与环境相适应的结果。

| Abstract: | Three rice landraces that have been continuously cultivated in Yuanyang County for hundreds of years by the local Hani people and three modern varieties cultivated in this area for 3-5 years were comparative tested on seven major agronomic characteristics at six different altitudes in the Yuanyang paddy field. The results indicated that agronomic characteristics of the landrace varieties, such as plant height, panicle length and number of effective panicles of landraces had no significant difference at different altitudes, whereas, those agronomic traits fluctuated in the modern varieties. In the Yuanyang terrace area, the Yuanyang landraces showed greater diversity in phenotype and better adaptation compared to the modern varieties. |
