【Abstract】 A new sweetpotato variety Yanshu 29 was bred by Yantai Academy of Agricultural Scientific Research in 2009, which was a progeny of a cross among Yanshu 24 and multi-male by opening pollination. In the national Sweetpotato Regional Trial(2014—2015), the average starch yield of this variety was 469.9 kg/667 m~2,higher than the control variety Xushu 22 which increased 16.37%. It also had the highest dry matter content of 34.55% at this round of trial, which increased significantly by 20.26%. The cooked taste score of Yanshu 29 occupied the first among all the varieties, with 74.7, which benefited from the highest sweetness, fragrance and crude fiber content. This variety had the characteristics of white and smooth chips and high-quality slowly digestible starch. It was identified by the National Sweetpotato New Varieties Appraisal Committee in May 2016, and suitable for planting in sandy loam land.更多还原
