Abstract:
In order to explore the distribution status of wild kiwifruit germplasm resources and mining excellent wild kiwifruit germplasm with breeding value,lay the foundation for rational development and utilization of wild kiwifruit resources in this area,wild kiwifruit germplasm resources in Wufu Mountain from 2017 to 2018 were collected and evaluated.The results showed that Wufu Mountain was rich in wild kiwifruit germplasm resources,of which wild Actinidia eriantha was in the majority,accounted for 78.88%.A total of 161 wild kiwifruit germplasm was collected,of which 77 were male and 50 were female of A.eriantha;there were 20 A.chinensis,including 6 males and 14 females;14 A.hemsleyana,including 3 male and 11 female kiwifruit germplasm.The distribution of wild kiwifruit germplasm spans from 636 m to 1 041 m above sea level,with cross distribution of male and female plants.According to the investigation results,20 excellent pollinated male germplasm with more than 6 000 single anther pollen,more than 120 stamens and more than 80% pollen activity were dug out from wild kiwifruit germplasm.3 large fruit germplasm with single fruit weight of more than 20 g;the dry matter content of the fruits of the 3 high dry matter germplasm varieties was more than 17% after soft ripening.It can provide the original material for the breeding of excellent germplasm and the genetic improvement of varieties.
