Description

[0001] Latin name of the genus and species claimed: Vitis vinifera.

[0002] Variety denomination: ‘SUGRA78’.BACKGROUND AND SUMMARY

[0003] This application relates to the discovery and asexual propagation of a new and distinct variety of grapevine ‘SUGRA78’, as herein described and illustrated. The new variety was first selected as breeder number ‘GR1067R’ by Terry A. Bacon and Terrence J. Frett in Wasco, Kern County, California in July 2021. The variety was originated by controlled hybridization.

[0004] The new variety ‘SUGRA78’ is characterized by the production of a large-sized, red and obtuse ovate berry with a mid-season ripening date. The berries of ‘SUGRA78’ are very firm and very juicy.

[0005] The seed parent is ‘GR379B’ (unpatented) and the pollen parent is ‘Sugrafortyeight’ (U.S. Plant Pat. No. 27,791). The parent varieties were first crossed in April 2018. The date of first sowing was March 2019, and the date of first flowering was April 2020.

[0006] The new variety ‘SUGRA78’ was first asexually propagated in December 2021 in Wasco, Kern County, California, by Terry A. Bacon and Terrence J. Frett using hardwood cuttings.

[0007] The new variety ‘SUGRA78’ can be distinguished from its pollen parent ‘Sugrafortyeight’ (U.S. Plant Pat. No. 27,791) in that while both varieties have rudimentary seed traces, the ripening of the berries of the new variety ‘SUGRA78’ starts on August 8th, compared to August 5th for ‘Sugrafortyeight’. Additionally, the new variety ‘SUGRA78’ has a berry weight of 9.2 g and a cluster weight of 730 g, compared to a berry weight of 11.8 g and cluster weight of 870 g for ‘Sugrafortyeight’. Further, the new variety ‘SUGRA78’ has an obtuse ovate shaped red colored berry, compared to a black colored and broad elliptic shaped berry for ‘Sugrafortyeight’

[0008] The new variety ‘SUGRA78’ can be distinguished from its seed parent ‘GR379B’ (unpatented) in that while both varieties have rudimentary seed traces and obtuse ovate shaped berry, the new variety ‘SUGRA78’ has a berry weight of 9.2 g and a red colored berry, compared to a berry weight of 7 g and a black colored berry for ‘GR379B’. Additionally, the new variety ‘SUGRA78’ has a cluster weight of 730 g, compared to 650 g for ‘GR379B’. Further, the ripening of the berries of the new variety ‘SUGRA78’ starts on August 8th, compared to August 5th for ‘GR379B’.

[0009] The fruit of the new variety ‘SUGRA78’ has rudimentary seed traces and a red colored berry like ‘Sheegene-12’ (U.S. Plant Pat. No. 20,252), but the new variety ‘SUGRA78’ has an obtuse ovate shaped berry, compared to an ovate shape for the berry of ‘Sheegene-12’. Additionally, the new variety ‘SUGRA71’ has a berry weight of 9.2 g and a cluster weight of 730 g, compared to a berry weight of 8 g and a cluster weight of 600 g for ‘Sheegene-12’. Further, the ripening of the berries of the new variety ‘SUGRA78’ starts on August 8th, compared to August 5th for ‘Sheegene-12’.

[0010] The fruit of the new variety ‘SUGRA78’ has rudimentary seed traces and a red colored berry like ‘IFG-68-175’ (U.S. Plant Pat. No. 21,664), but the new variety ‘SUGRA78’ has a berry weight of 9.2 g and cluster weight of 730 g, compared to a berry weight of 7.5 g and a cluster weight of 650 g for ‘IFG-68-175’. Additionally, the new variety ‘SUGRA71’ has an obtuse ovate shaped berry, compared to the broad elliptic shaped berry of ‘IFG-68-175’. Further, the ripening of the berries of the new variety ‘SUGRA78’ starts on August 8th, compared to August 10th for ‘IFG-68-175’.

[0011] The fruit of the new variety ‘SUGRA78’ has rudimentary seed traces and a red colored berry like ‘Flame Seedless’ (unpatented), but the new variety ‘SUGRA78’ has a berry weight of 9.2 g and cluster weight of 730 g, compared to a berry weight of 4.8 g and cluster weight of 550 g for ‘Flame Seedless’. Additionally, the new variety ‘SUGRA78’ has an obtuse ovate shaped berry, compared to a globose shaped berry for ‘Flame Seedless’. Further, the ripening of the berries of the new variety ‘SUGRA78’ starts on August 8th, compared to July 5th for ‘Flame Seedless’.

[0012] The new variety ‘SUGRA78’ has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, cuttings and grafting.

[0013] Variations of the usual magnitude from the characteristics described herein may occur with changes in any of a variety of factors such as growing conditions, irrigation, fertilization, pruning, management and climatic variation.BRIEF DESCRIPTION OF THE DRAWING
