摘要
郑红23号是河南省农业科学院粮食作物研究所2007年以世中1号为母本、徐薯18号作父本,从其杂交后代中选育出的食用与淀粉加工兼用型甘薯新品种。在河南省甘薯区试中,其平均鲜薯产量、薯干产量和淀粉产量分别为32 799.75 kg/hm2、9 437.25 kg/hm2和6 081.00 kg/hm2,分别比对照徐薯22增产10.57%、12.13%、11.11%。该品种抗茎线虫病和根腐病,中抗黑斑病,抗旱、耐瘠、耐贮藏,稳产性和适应性好,食味较好。
A new dual-purpose sweetpotato variety Zhenghong No.23 was bred in 2007 by Food Crop In-stitute of Henan Academy of Agricultural Sciences using Shizhong No.1 as female parent,Xushu No.18 as male parent.In the Henan’ s sweetpotato regional test,the average fresh yield,dry yield and starch yield were 32 799.75 kg/ha,9 437.25 kg /ha and 6 081.00kg/ha,and increased by 10.57%,12.13 %and 11.11%compared with the control Xushu No.22 respectively.The variety also presented many other better characters,such as better resistance to stem nematode and root rot ,middle resistance to black spot, better tolerance to drought and barren,better storability,better yield stability ,better adaptability and good taste.
