摘　　要：宝光是常规杂交培育成的早熟、大粒、优质葡萄新品种,其母本为巨峰,父本为早黑宝。果穗圆锥形,平均单穗质量717.3 g,果粒近圆形,平均单粒质量13.7 g,最大单粒质量25.0 g,每果粒含种子1~3粒;果皮紫黑至蓝黑色,果粉较厚,果肉较脆,香气淡;可溶性固形物含量(w,后同)18.1%以上,最高23.5%;可滴定酸含量为0.47%,固酸比38.3;品质上等。昌黎地区果实成熟期为8月上旬。适宜河北、山东、山西、浙江、湖北、广西等适栽地区种植。Baoguang is an early-season table grape with high quality and large berries.The cultivar was bred from a cross between Kyoho and Zaoheibao in May 2003.Initially,3098 hybrid seeds were obtained and stratified in 2003.From these seeds,1293 hybrid seedlings successfully established in 2004.Baoguang was selected in 2006 for its comprehensive performance and tested as C 4-6-4.Then it was evaluated in regional trials in Luannan,Tanghai,and Changli in 2008 and proved to have good fruit quality and high yield.In 2013,this selection was certificated by Hebei Province Forest Variety Certification Committee and named Baoguang.Its vines are moderate to high in vigor on their own roots.The tip of the young shoots has sparse hairs.The young leaf is in green color with yellow spots and the intensity of anthocyanin coloration in the shoot tip is medium.The mature leaf is green,not villous at lower surface and glossy at upper surface.Mature leaves are pentagonal with five lobes and shallow upper cracks.The petiole depression is half open with a“V”shape at the base.The hermaphrodite flowers are usually positioned at the fourth or fifth node.The cluster of Baoguang is large-sized,and conical in shape with no shoulder.The average bunch weight of Baoguang is 717.3 g.The cluster is 19.2 cm in length and 16.5 cm in width on average.The almost round berry has an average weight of 13.7 g,and can be up to 25.0 g in weight,25.9 mm in width and 29.2 mm in length.The berry contains 1 to 3 seeds and the one hundred seed weight is 9.9 g.The flesh is slightly crispy.The skin is thin to medium thick with a purple-to blue-black color.The soluble solid content is 18.1%on average and can be up to 23.5%;the average titratable acid content is 0.47%;and the ratio of soluble solids to titratable acid is 38.3.In Changli,bud breaks in middle April;florescence occurs in late May and fruit matures in early August.The average period from bud burst to harvest is 117 d.The average bearing shoot ratio is 78.3%and the number of clusters in each bearing shoo
