Breeding of a new yam cultivar Qunuoyu No.1
摘要
Abstract
To address challenges such as varietal degradation and poor disease resistance in Chinese yam production in Zhejiang province,a new high-yield,disease-resistant cultivar named Qunuoyu No.1 has been successfully developed via systematic selection.It was derived from a local Chinese yam landrace(accession No.2015-11)indigenous to Quzhou.This cultivar features a growth cycle of approximately 217 days and an average of 6.2 branches per plant.The main vine is green,ribbed,and displays a right-handed twist,with no bulbils formed.The tubers are cylindrical in shape,character-ized by purple skin and white flesh.On average,each tuber attains a length of 24.3 cm,a width of 10.0 cm,and a sin-gle-tuber mass of 1 534.0 g.Nutritionally,it contains 22.6%starch content 1.44%soluble sugar content and 2.24%pro-tein content.The flesh exhibits moderate viscosity,excellent browning resistance,and soft,glutinous with traits highly fa-vored by consumers.Furthermore,Qunuoyu No.1 demonstrates moderate resistance to anthracnose,a major fungal dis-ease affecting Chinese yam.In regional adaptability trials,the cultivar achieved an average yield of 1 994.4 kg·667 m-2.Qunuoyu No.1 is well-suited for cultivation in Zhejiang province and other regions with analogous climatic and edaphic conditions.关键词
