The present invention relates to a new and distinct grapevine variety, botanically known as Vitis vinifera L., and hereinafter referred to by its variety denomination ‘SWEET JASPER’.
The new grapevine ‘SWEET JASPER’ is a product of a controlled breeding program conducted by the inventors, Avichai Perl, Nachman Sahar, Oded Degani, Tatiana Okun, Arie Sarfian, Hanan Bazak, Refael Eliassi and Ahuva Daos at The Volcani Center, located in Bet Dagan, Israel. The objective of the breeding program was to develop a new early ripening, very fertile grapevine variety particularly characterized by attractive berries with yellowish green color which are uniform in size and shape and are firm with tender crunchy skin.
The new grapevine ‘SWEET JASPER’ originated from a cross made by the inventors in 2004 at The Volcani Center. The female or seed parent is the grapevine Vitis vinifera L indicated as ‘ARO 2117’ (unpatented), in the inventors' collection located in Bet Dagan, Israel, and the male or pollen parent is the grapevine Vitis vinifera L. indicated as ‘ARO 1717’ (unpatented), in the inventors' collection.
The new grapevine ‘SWEET JASPER’ was observed and selected by the inventors within the progeny of the stated cross in a controlled environment in 2007 at The Volcani Center.
Asexual propagation of the new grapevine variety by bud grafting was first performed in January 2008 at The Volcani Center, and has demonstrated that the combination of characteristics as herein disclosed for the new variety is firmly fixed and retained through successive generations of asexual propagation. The new cultivar propagates true-to-type.
