山樱桃单株苗期试验比较研究

A STUDY ON THE PROVENANCE SEEDLING TRIAL AND COMPARATION OF Prunus verecunda(Koidz.)Koehne

2007年-2008年对固阳、凉城、乌拉山等种源的山樱桃进行苗期试验的比较分析研究。对生长性状、抗性、适应性进行定期,定株观测调查,叶片数和小枝数等数量性状亦进行了观测。对观测结果采用方差分析、一般配合力估算、秩次排序等方法进行数据处理。结果表明,种源间生长性状差异明显,种源内单株间差异亦明显,叶片数,小枝数等数量性状发生了系列变化,抗性、适应性等亦表现不同程度的差异。初步筛选出32个优良单株其中：固阳种源：3号,16号,50号等13个单株;和乌拉山种源：2号,4号,50号等8个单株;和凉城种源：4号,5号,45号等10个单株,为优良品种或良种的选育提供了依据。

From 2007 to 2008, of Guyang, LiangCheng, Wulashan provenance Prunus verecunda（ Koidz. ） Koehne seedling trials carried out a comparative analysis of research. On the growth traits, resistance, and adaptability to regular, fixed - line observation survey, quantitative traits such as the number of leaves and sprigs were also observed. Use data - processing methods to process observations, such as variance analysis, GCA estimates, rank sort and so on. The results show that,the growth traits obvious difference between Provenance, are also obvious differences between the plant inside provenance. Quantitative traits such as the number of leaves and sprigs were also come about a series of changes, resistance, and adaptability and so on are also varying degrees of difference in performance. Preliminary screening of a fine of 32 per plant are as follows ： Guyang Provenance： 3,16,50 ; Wulashan Provenance： 2,4, 50; Liangcheng Provenance： 4,5, 45 ,for the good of the species or varieties provided the basis for selection.
