摘要:

摘 要:根据在榛子抗寒鉴定圃对平欧杂种榛无性世代榛树7年(2000—2006)的观察与研究提出:1)平欧杂种榛无性世代的雄花NFDA1葇荑花序一般比雌花早2~3年;2)坚果大小和NFDA1葇荑花序柱体大小的数量性状指标间呈现出显著或极显著正相关,而坚果壳厚度与NFDA1葇荑花序柱体长度(L)和中部横径(R)的比值(T)呈现显著的负相关;3)根据本文提出的回归方程在榛树结果前2~3年预测坚果大小和果壳的厚度,提前淘汰NFDA1葇荑花序过细小的株系或品系,缩短育种年限。

Abstract:

Abstract: According to observation and study on filbests of agamic generation of Corylus heterophylla×C. avellana in a testing plot of cold-resistance hazelnut for 7 years (2000—2006), the results are reported for the first time at home and abroad in the crossbreeding field of hazelnut as follows: 1)The flower of catkin of the agamic generations of C.heterophylla×C. avellana was generally 2~3 years earlier in comparison with blossoming female and bearing fruit;2) There was a significantly or extreme significantly positive correlation between nut size and column size of the catkin, while there was significantly negative correlation between thickness of nut shell and ratio (T) of the length(L) to central section horizontal diameter (R) of catkin column; 3) The nut size and the shell thickness were able to be predicted in advance of 2~3 years before bearing the hazelnut, therefore those plants with small catkin column could be eliminated in order to shorten the crossbreeding time.
