【摘要】 选用5个高油玉米品种和长治地区的主栽玉米品种郑单958进行生长发育、产量及含油量的比较。结果表明,大丰高油303全生育期偏短,产量极显著低于对照郑单958;QS-T的全生育期偏长;ND621,ND698,高油5580的全生育期和对照郑单958基本一致,含油量均极显著高于对照,ND621和ND698的产量与对照郑单958间差异不显著,高油5580的产量与对照郑单958间差异未达到极显著水平。ND621,ND698和高油5580是长治地区发展高油玉米生产的适宜品种。更多还原

【Abstract】 The paper compared the growth,the yield and the grain oil content of five high oil maize varieties with those of Zhengdan958 which was planted mainly in Changzhi area. The results showed that Dafeng High Oil 303 had a shorter growing period, and its yield was lower very significantly than that of the contrast. And QS- T had a longer growing period. The growing periods of ND621, ND698 and High Oil 5580 were almost consistent with that of the contrast. And the grain oil contents were all very significantly higher than that of the contrast. There was no significant difference between the yield of ND621, ND698 and that of the contrast,the yield difference between High Oil 5580 and the contrast wasn’t very significance level. So, ND621, ND698 and High Oil 5580 were suitable varieties in Changzhi area.更多还原
