A new seedless table grape cultivar ‘Zhufeng'

Abstract: ‘Zhufeng'grape is a new variety that found from a natural population of‘Kyoho'grape. In2011, a variant of the‘Kyoho'grape was found in a natural population of‘Kyoho'grape in a vineyard in Lion Bridge Village, Luolong District, which is seedless and ripe 5-7 days earlier than the‘Kyoho'.From 2014 to 2017, after the observation of the experimental units in Luolong District and Mengjin County in Luoyang, Xiuwu County in Jiaozuo, and Shangshui County in Zhoukou, it is found that the genetic trait of‘Zhufeng'is stable, and the comprehensive traits are excellent, which are seedless, granule, high quality, long hanging tree time and other advantages. The results of systematic observation and supporting technical research on botany characteristics, biological traits and agronomic traits show that the seedless traits and fruit quality are in line with the current breeding goals. In March2017, it was approved by the Henan Provincial Forest Varieties Approval Committee and named‘Zhufeng'. Fruit clusters are cylindrical or conical, with an average cluster mass of 850.3 g; The fruit grains are nearly round, the natural grain mass is 6-7 g, the average single grain mass treated with gibberellin is 15 g, and the skin is black; The flesh is crisp and sweet; Soluble solids content, quality, etc.Seedless rate is more than 90%. It matured in middle and late August in Luoyang, which is 5-7 days earlier than‘Kyoho'. Plants have strong growth potential, strong adaptability and resistance to disease, and are easy to cultivate.
