摘要:

以4个新疆主栽平欧杂种榛品种(系)达维、辽榛7号、玉坠、平欧15号作母本,平欧杂种榛1-25、84-102、85-57、84-5、B-21作父本,按照测交系遗传交配设计,进行控制授粉,对杂交所得果实性状进行配合力分析,旨在阐明平欧杂种榛授粉树配置的可行性及双亲对其果实性状的影响.方差分析结果表明: 在亲本亲和的基础上,4×5测交系遗传交配设计中不同杂交组合间的结实率差异不显著; 杂交所得果实性状在不同杂交组合间的差异均极显著,重复区组间的差异不显著.配合力效应分析结果表明: 亲本的一般配合力效应占较大的方差分量,母本的一般配合力效应达到极显著程度,而特殊配合力效应及父本效应较小,平欧杂种榛种内杂交果实性状以其加性效应占优势且受母本的影响比较大.平欧15号凭借其优良的果实性状和较好的果实外形品相,更适合作为主要品种在新疆推广.父本84-5凭借其果仁三径均值、果仁质量、出仁率、果腔系数的一般配合力最大且为正向效应,果壳厚为负向效应,有利于果实的经济效应,适合作为授粉品种.

Abstract:

In this study, four hybrid hazelnuts (Corylus heterophylla×C. avellana), main cultivars in Xinjiang, named Dawei, Liaozhen7, Yuzhui and Ping'ou15, were used as maternal parent and the hybrid hazels of 1-25,84-102, 85-57,84-5,B-21 as male parents for controlled pollination according to a testcross mating design. The combining ability of the parents was analyzed based on nut characters of intraspecific cross to illuminate the feasibility of hybrid hazelnut pollination tree configuration and the influence of parents on their fruit characters. The results of variance analysis showed that these nut characters of intraspecific crosses displayed significant differences among seven different hybridized combination, but not significant differences between repeated blocks.The general combining ability and the maternal effects were significant, while the special combining ability and the male effects were not significant. These nut characters of intraspecific crosses were mainly controlled by the additive gene effects and affected more by the maternal. Ping'ou15, should be used as a main variety, and further promoted in Xinjiang because of its excellent fruit quality parameters and its better fruit shape. The male parent 84-5 could be regarded as the main pollination cultivars because of the greatest general combining ability of the nut three diameter mean value, fruit weight, kernel rate and the fruit cavity coefficient. Additionally, the shell thickness has a negative effect, which all are conducive to nut economic characters and make it suitable to be used as a pollinating cultivar.
