摘要
以猕猴桃属中华猕猴桃(Actinidia chinensis)32个品种和1个种间杂交后代群体为研究对象,对猕猴桃属植物叶片与果实维生素C含量的相关性进行了研究。结果表明,在中华猕猴桃种内水平上,幼果与成熟果实的果肉维生素C含量间存在极显著的正相关关系;在种间杂交后代群体中成熟叶片和成熟果实的维生素C含量存在极显著正相关关系,为利用早期相关性状开展猕猴桃育种的可行性提供了理论依据。此外,对15个常见中华猕猴桃品种的果实维生素C含量进行了多重比较,为人工杂交时的亲本选择提供了依据。
The leaf and fruit vitamin C contents of two Actinidia populations were studied and the correlation coefficients were measured.One population consists of 32 cultivars of A.chinensis and the other is an interspecific population of 22 individuals.There's a significant positive correlation between the young and mature fruit vitamin C content among the A.chinensis cultivars,and significant positive correlation between the mature leaf and mature fruit vitamin C content among the interspecific hybrids.This provided a scientific basis for the feasibility and practicality of early selection in Actinidia breeding.In addition,the results of multiple comparisons among the fruit vitamin C contents of famous cultivars provide some hints for choosing parents in breeding for high fruit vitamin C content.
