草莓主要农艺性状相关分析及通径分析

摘要

为了研究影响草莓单株产量的主要农艺性状与单株产量之间的关系,利用178份草莓杂交后代材料,对平均单株产量和其他12个农艺性状进行相关分析和通径分析.结果表明:平均果数/株、平均果重/株和最大果重是增产的重要因素,因此,在育种实践中必须协调好两者的关系,以增加平均果数/株对提高株产的最大作用.%178 strawberry hybrid progeny materials were used to study the relationship between the yield per plant and mian agronomic characters by correlation analysis and path analysis. The results showed that the average fruit number per plant, the average fruit weight per plant and the biggest fruit weight were the principle factors increasing the strawberry yield. Therefore, increasing the average fruit number of per plant was the key of breeding.
