| Abstract:
In 1986, an ambisexual flower bud mutation was discovered on a top grafting staminiferous shoot of Actinidia Chinensis Planch in truly wild resources and selective breeding plants orchard of Horticultural Institute of Jiangxi Province. This mutant had some flowers in diverse development, a part of these flowers had obvious bisexual bloom traits; such flowers showed subglobose ovary in 0.5 x 0.7 cm. diameter, style in 0.2 cm. length, pollen germination from 46% to 53.7%, fertility in autogamy, natural pollination and xenogamy within species as father parent. Fruits demonstrated oblate spheroid, 12.3 gram average fresh weight, 24.0 gram maximum weight, viridescent yellow flesh, after ripening total soluble solid matter (abbreviated to T. S. S.) from 17.2% to 18.0%, ascorbic acid in 234 mg. per 100 gram pulp, when picked in the first ten days of November T. S. S. at 10.5%, no preharvest drop, keeping about one month in house temperature. It is seemed to be a valuable germplasm resource for breeding a hermaphrodite variety. | |
