采用水插雄花枝法进行的控制杂交试验表明,平榛优系———平选1号同平欧杂种榛辽榛4号、辽榛1号、1-21等3个品种、品系杂交亲和性良好,正反交的花序座果率均在79.7%以上。平选1号同平欧杂种榛84-1、1-20、2-20等3个品系正反交均不亲和。以平选1号作母本,达维作父本的正交组合不亲和,以平选1号作父本,达维作母本的反交组合亲和性差,花序座果率14.4%。以平选1号作母本,B6、Butler、Royal和Casina等4个欧榛品种分别作父本的杂交组合的花序座果率依次为10.8%、15.6%、16.5%、21.6%。
The control hybridization experiment using water plug male and female branch method showed that the Ping hazel excellent line --- Ping-1 No. 1 was the same as the European hybrid hazel Liao-han No.4, Liao han No.1, 1-21 and other 3 varieties, And sex is good, reciprocal reciprocal inflorescence fruit rate are above 79.7%. Ping-ping No. 1 with the same European hybrid hazel 84-1, 1-20, 20-20 and other three strains of anti-cross are not affinity. In order to Pingxian 1 as the mother of Davis, as the father of the orthographic combination of non-affinity to Ping election No. 1 as the father, David as the mother of the anti-crossover combination of affinity, inflorescence fruit rate of 14.4% . The results showed that the fruit rate of inflorescences was 10.8%, 15.6%, 16.5% and 21.6%, respectively, for the parents of four Hazelnut varieties such as B6, Butler, Royal and Casina.
