| 为探究区试点与品种对谷子农艺性状的关联关系及影响效应，于2014和2015年分别在山西五台县（A1）、山西定襄县（A2）、山西平定县（A3）、山西省农科院高粱所（A4）、山西省农科院经济作物所（A5）、山西省农科院谷子所（A6）和山西高平市（A7），选取种植谷子‘长杂谷1205号’（B1）、‘长农44号’（B2）、‘长生13号’（B3）、‘晋汾97号’（B4）、‘农大8号’（B5）与‘长农35号’（B6），每个品种3次重复。结果显示，A1的谷子株高显著高于其他区试点的，且其穗长显著高于A6穗长。A2、A3生育期与A1、A7的差异达到显著水平，A4的谷子穗粒重及产量高于其他区试点，A5在千粒重方面有促进作用。A6的主茎高显著低于其他区试点，A7的穗长显著高于其他区试点。通过一年多点综合分析得B1品种的生育期、穗数在各地均高于其他品种，在穗长方面的变异度最高。B3品种在千粒重、主茎高方面的丰产效应最低，而B5在穗长、千粒重及产量方面的丰产效应最高。B6的穗长及产量的丰产效应为负效应，且其生育期、穗数及主茎高变异系数最高，但对主茎高的增高效应最高，而其穗数在A2表现最好。综上所述，区试点与品种在谷子农艺性状方面有交互作用，其中品种对谷子穗长、主茎高影响效应大。 |

| Abstract: |
| In order to explore the effects of experimental sites and varieties on the agronomic traits of millet,this study investigated the agronomic traits of 6 millet varieties planted in 7 typical areas in Shanxi Province on 2014 and 2015.The experiment of each variety was repeated 3 times.The results showed that the plant height of the millet in the Shanxi province Wutai County area was significantly higher than that in other areas,and its panicle length was significantly higher than that in the Shanxi province Changzhi County.The difference between the growth period in the Shanxi province Dingxiang County,Shanxi province Pingding County and the difference between the pilots in the Shanxi province Wutai County and Shanxi province Gaoping County areas both reached a significant level.The spike grain weight and yield of the millet at the pilot in the Shanxi province Yuci County were higher than those in other areas.And the Shanxi province Fenyang County pilot had a positive effect on the 1 000-grain weight than those in other areas.The main stem height in the Shanxi province Changzhi County was significantly lower than that in other districts,and the length of spike in the Shanxi province Gaoping County trial was significantly higher than that in other districts.Through more than one year's comprehensive analysis,it was found that the growth period and number of spike of ‘Changzagu 1205’ were higher in all regions than in other cultivars,and the variability in length of spike was the highest.The Changsheng 13 had the lowest yield effect in 1 000-grain weight and main stem height.‘Nongda 8’ had the highest yield effect in panicle length,1 000-grain weight and yield.However,the high yield effect of panicle length and yield of ‘Changnong 35’ displayed negative effect,and its growth period,panicle number and main stem high coefficient of variation were the highest.But the increase effect on the height of main stem was the highest,and the panicle number was the best in Shanxi province Dingxiang County.In summary,the pilot sites and varieties showed interactions in agronomic traits of millet.The varietal factors had greater influence on the length of spike of millet and the height of the main stem. |
