| 摘 要： | 以巴西旱稻艾巴9号为对照,对旱稻502、旱稻10号等5个品种进行小区比较试验。结果表明,5个品种的产量都明显高于对照,为3847.5~5497.5kg/hm2,比对照增加6.6%~52.2%,差异达极显著水平,以旱稻502、旱稻10号的增产幅度最高。通过对经济性状、农艺性状等进行考查,旱稻502、旱稻10、旱稻65号在田林县高寒山区表现为丰产性优、抗性强,适宜大面积推广种植;中旱3号、旱稻277表现为丰产性较低,抗性较差,不适宜大面积推广种植。

| Abstract: | Brazilian upland rice Aiba 9 was used as the control,comparison experiments of five new upland rice varieties such as Handao 502 and Handao 10 etc.,were carried out.The results showed that the yield of five varieties were 3847.5-5497.5kg/hm~2,which was highly significantly higher than that of the control with increase rate up to 6.6%-52.2%,and the yield of Handao 502 and Handao 10 were the highest.The economic and agronomic characters of all varieties were investigated,and it showed that Handao 502,Handao 10 and Handao 65 were of good productivity and strong resistance,and can be extended in a large scale;on the contrary,Zhonghan 3 and Handao 277 were of poor productivity and low resistance and is not suitable for extension. |
