摘要 为改变平欧杂交榛引种栽培时,品种未经驯化,适应性差,经济效益低的现状,推进赤峰市榛子产业结构合理化,赤峰市林业科学研究院引进一批平欧杂交榛子品种(品系)进行引种栽培。以辽榛7号、辽榛3号、达维、玉坠、薄壳红、平欧48号、平欧21号7个品种(品系)为研究对象,定植在赤峰市林业科学研究院科研试验基地,进行引种试验。以成活率、保存率及初期生长情况为依据,进行灰色关联分析,结果表明,玉坠与理想品种的关联系数最大,γ=0.782 5,为7个品种(品系)的参评最优品种。

Abstract In order to change the current situation that the variety was not acclimated, the adaptability was poor and the economic benefit was low,promote the rationalization of the industrial structure of hazelnut in Chifeng City,Chifeng Academy of Forestry introduced a number of hybrid hazelnut(Corylus heterophylla×Corylus avellana) varieties for introduction and cultivation.In this study seven varieties(strain) were used as the research object,which were Liaozhen No.7,Liaozhen No.3,Dawei,Yuzhui,Bokehong, Pingou No.48,Pingou No.21.They were colonized in research and experiment base of Chifeng Academy of Forestry.With survival rate,preservation rate and initial growth as the bases for the grey correlation analysis,the result indicated that the variety of Yuzhui had the evenly high correlation with the ideal varieties, which was the best variety of seven hybrid hazelnut varieties (strains),γ=0.782 5.

榛樹(Corylus L.)是重要的干果和木本油料树种[1]。我国榛子资源丰富,自有的榛子多为平榛(Corylus heterophylla Fisch)、毛榛(Corylus mandshurica Maxim.)[2],辽宁省经济林研究所利用我国的平榛(Corylus heterophylla Fisch)与引进的欧洲榛(Corylus avellana L.)种间远缘杂交,成功地育成了平欧杂交榛(Corylus heterophylla Fisch.×Corylus avellana L.)。1999年辽宁省经济林研究所培育出薄壳红、达维、平顶黄、金铃、玉坠5个新品种[3],2006年鉴定了第二批平欧杂交榛辽榛1号、辽榛2号、辽榛3号和辽榛4号共4个品种[4],抚顺市林业科学研究所2009年鉴定了第三批平欧杂交榛辽榛5号、辽榛6号2个品种[5-6],2013年辽宁省经济林研究所选育的辽榛7号(82-11)、辽榛8号(81-21)、辽榛9号(84-69)通过了鉴定。平欧杂交榛集中了平榛和欧洲榛的优良特性,具有抗寒性与适应性强、坚果大、丰产、出仁率高的特点[7]。安徽、河南、新疆、黑龙江、山西、北京等省区先后开展榛子引种相关工作[8-11]。……
