Abstract:
Abstract:The 26 populations from six wild kiwifruit species were used as test materials，the analysis of morphological variation and ITS sequence in 26 populations from six wild kiwifruit species were conducted to study the genetic relationships and the effect of population locality for morphology variation,in order to provide reference for future studies on the wild kiwifruit resources protection and utilization.The results showed that analysis of means showed that the six species of kiwifruit mainly differed in petiole length，internode length，fruit size and quality characteristics.The results of principal component analysis indicated that maximal fruit length，minimal fruit length，trichomes of fruit，trichomes of stem，trichomes of petiole，trichomes of leaflets (adaxial side)，trichomes of leaflets (abaxial side)，minimal petiole length，maximal petiole length，minimal internode length，maximal internode length were the main interspecific morphological differences.There were obvious morphological differentiation among species and populations which had a certain relationship with geographical distribution.The analysis of Qcluster and principal component analysis showed that the six kiwifruit species were grouped into 2 categories，A.chinensis var.deliciosa was clustered as a class and the other five kiwifruit species were anothor one.
