玉米新品种比较试验

Comparative Experiment of New Maize Varieties

[目的]筛选适宜在新疆石河子地区种植的高产、优质、抗病、熟期适中的杂交玉米新品种。[方法]通过12个玉米品种进行田间对比试验,并对各品种主要农艺性状、室内考种和田间产量进行比较分析。[结果]各玉米品种的生育期具有明显差别;川单14株高、穗位高均最高;2个密度条件下MC716产量均最高,较对照分别增产5.56%和16.62%,综合抗病性强,果穗外观品质优。[结论]MC716、先玉335、浚单20、沈单16、DH6053、Mc103、吉单261品种可以作为新疆石河子地区主推品种。

[Objective] The aim was to select the suitable and fine maize varieties with the characteristics of high yield,good quality,disease resistance and moderate maturity in Shihezi of Xinjiang.[Method] 12 maize varieties were conducted to carry out comparative analysis on their agro-characteristics,lab test data and field yield.[Result] Differences of growth period of all maize varieties were significant.The plant height and ear height were highest.The yield of MC71 was highest and increased by 5.56% and 16.62% comparing with control groups under two densities,in addition,it had highest disease resistance and the appearance with relatively excellent quality.[Conclusion] MC716,Xianyu335,jundan20,Shendan16,DH6053,Mc103,Jidan261 can be viewed as main varieties in Shihezi of Xinjiang.
