| Abstract: | A new high starch-type sweetpotato variety Luoshu No.11 was developed from the progenies by crossing CIP194037-1 from the International Potato Center as female parent with many male parents by the Luoyang Academy of Agricultural and Forestry Sciences and Luoyang Jinguwang Seed Industry Co.,Ltd..The starch content stands out in the Provincial Regional Trials(taking the principal variety "Xushu 22" as the control) and Provincial Production Trials(taking the principal variety "Xushu 18" as the control) of Henan,in National potato north district Regional Test and Production Trials(taking the principal variety "Xushu 22" as the control).The average yield of starch and fresh yield were 6 220.1,29 258.8 kg/ha,increased by 18.38% and 0.90% compared with the check variety,respectively.The rate of starch was 21.26%,increased by 3.14 percentage points compared with the check variety.The dry starch content was 64.43%,increased by 3.77 percentage points compared with the check variety Xushu 22.The variety was resistant to stem rot,middle rootrot and stem-nematode,infected with Marssonina brunnea.The variety had strong disease resistance and wide adaptability,passed the identification of new variety by Henan province and nation in 2012 and 2016 respectively,which was a relatively ideal varieties for starch processing,and suitable for spring and summer cultivation. |
