文冠果品种引种筛选试验

Introduction and screening experiment of Xanthoceras sorbifoliaBunge varieties

【目的】为了筛选出适合鄂尔多斯地区综合品质优良的文冠果品种,为鄂尔多斯地区的木本油料产业发展提供优质品种来源。【方法】以丰产文冠果新品种——中石4号、中石9号、蒙冠1号、蒙冠2号、蒙冠3号为引种试验材料,以本地红花文冠果和本地普通文冠果2个品种为对照,对这7个文冠果品种进行综合性状观测调查,采用指标直观数据差异显著性分析和主成分分析相结合的方法来评价筛选综合品质优良且适宜在鄂尔多斯栽培的文冠果品种。【结果】不同品种指标间显著性差异分析结果显示,文冠果不同品种之间存在不同程度的性状差异。本地2个文冠果品种在生长性状方面表现较为优良,在果实产量与种子品质方面表现较差;引进的中石4号、中石9号和蒙冠1号在果实产量与种子品质方面表现出优良特性,生长性状方面居中;蒙冠2号、蒙冠3号生长性状表现最差,果实产量与种子品质表现居中。通过主成分分析法对各品种指标进行综合和简化,最终筛选出了3个综合性状较好的文冠果新品种——中石9号、蒙冠1号、中石4号。【结论】鄂尔多斯地区可引种栽培中石9号、蒙冠1号、中石4号3个新品种,可将其作为木本油料产业原料林在鄂尔多斯地区适度发展。

【Objective】In order to select excellent Xanthoceras sorbifolia varieties and to provide high quality varieties for the development of woody oil industry in Ordos region.【Method】X.sorbifolia zhongshi No.4,X.sorbifolia zhongshi No.9,X.sorbifolia mengguan No.1,X.sorbifolia mengguan No.2 and X.sorbifolia mengguan No.3 were introduced as experimental materials,local red flower of X.sorbifolia and common X.sorbifolia were used as control.The comprehensive characters of seven X.sorbifolia cultivars were observed and investigated to evaluate and screen X.sorbifolia cultivars with good comprehensive quality and suitable for cultivation in Ordos by using the method of index intuitive data difference significance analysis and principal component analysis.【Result】The results showed that there were significant differences of characters among varieties.Two local cultivars showed better performance in growth characters,but poor in fruit yield and seed quality.X.sorbifolia zhongshi No.4,X.sorbifolia zhongshi No.9,X.sorbifolia mengguan No.1 showed excellent characteristics in fruit yield and seed quality,and the growth traits were in the middle.X.sorbifolia mengguan No.2 and X.sorbifolia mengguan No.3 had the worst growth traits,and the fruit yield and seed quality were in the middle. Principal component analysis was used to synthesize and simplify the indexes of each varietyto select three new X. sorbifolia cultivars with better comprehensive characters including X. sorbifolia zhongshi No.9, X.sorbifolia mengguan No.1 and X. sorbifolia zhongshi No.4.【Conclusion】Zhongshi No.9, mengguan No.1 and ZhongshiNo.4 can be introduced and cultivated in Ordos, and can be used as raw material forest of woody oil industry in Ordos.
