Abstract: 【Objective】 To explore the inheritance of the fruit traits of Ruby Seedless grape. 【Method】It evaluated the criteria of main fruit characteristics of the size of seed scar or seed, fruit fragrance, berry weight, surface color of pericarp, longitudinal and transverse diameter of fruit grains, content of soluble solids in fruits, stress tolerance of fruit grain and tensile tolerance of fruit pedicle by 134 progenies originating of Ruby Seedless × ''SP6164', and analyzed the genetic tendency of seed trait, fruit fragrance, berry weight, surface color of pericarp, fruit shape, sugar content in fruit, storage and transportation tolerance of fruits.【Result】Among the population, 55.97% were seedless, 4.48% were aromatic, and the weight of fruit grains tended to be moderately inherited. 91.8% were increased. The proportion of purple-red-purple was the highest (36.09%), mainly elliptic (55.9%), the heritability of fruit sugar content was 83.53%, and 8.96% of the super-high parents were inherited with average stress tolerance. The average heritability of pull tolerance was 119.27%, with 27.61% of the super-parent plants.【Conclusion】A large proportion of seedless progenies and a certain proportion of aroma progenies could be obtained by crossing Ruby Seedless with ''SP6164'', which was a fragrance line. The additive effect expression of each character index in the population could be obtained, but it was more significant in the two indexes of single grain weight and tensile endurance.
