杂交谷子株高与产量性状分析

采用完全随机区组设计,以当地生产主推品种晋谷21号为对照,研究了张杂谷3号、张杂谷5号、张杂谷9号、张杂谷10号和长杂2号在太谷地区的主要农艺性状和产量表现,并对其进行了方差分析、Duncan新复极差多重比较及相关分析。结果表明,杂交谷子品种产量均高于对照晋谷21号,增幅为7.3%～55.7%;除长杂2号外,其他杂交谷子品种株高均明显低于对照晋谷21号,但产量均明显高于对照晋谷21号;产量与穗长呈显著正相关,与株高呈显著负相关;穗长与穗质量、穗粒质量呈显著正相关;穗质量与穗粒质量呈极显著正相关。

Analysis of Plant Height and Yield Characters in Hybrid Millet

With the method of random complete block design and variety of Jingu 21,which widely grown in local area as check,we have studied the main agricultural characteristics and yield performances of Zhangzagu 3,Zhangzagu 5,Zhangzagu 9, Zhangzagu 10 and Changza 2.The results of this study were analyzed through the analysis of variance,Duncan's multiple comparison and correlation analysis.The results showed that yields of millet hybrid varieties were all higher than that of Jingu 21, the range of yield increasing was 7.3% ~ 55.7%;Except Changza 2,plant height of other millet hybrid varieties were significantly lower than those of Jingu 21,but the yield significantly higher than Jingu 21;The yield positively correlated with spike length,but negatively with plant height;the spike length and spike weight,grain weight per spike had a positive correlation;the grain weight per spike was positively correlated with the spike weight.
