油桐种质资源库品比试验初步研究

摘要

An investigation on the first collection of 54 tung oil strains in 2007 by the national genetic resources center, three years after afforestation and in the aspects such as the tree body, the growing of fruit characters and the yield and cross combinations selected was carried out with fuzzy mathematics. The results show that Hongyan 3, Luxi 1, tung oil plus tree 8 - 504 ,Xiqi4 and Long shanl displayed the best performance, and can use for the second phase- D project, which provide the breeding good strains and the comparison of regional breeding good strains material.%通过对国家油桐种质资源库2007年一期收集的54个油桐品系,在其造林后的第三年对树体结构、果实丛生性状及产量几个方面进行调查,并运用模糊数学方法,进行综合评判.研究结果表明:红岩3号、泸溪1号、优树8-504等5个品系表现最佳,并作为本项目的二期工程优良种质品比区、优良种质繁育区提供材料.
