New Wheat Variety'Wanmai 206'and Application of New Types of Nuclear Sterile Lines in Breeding Practice
Focusing on the unique climate characteristics of southern Henan,particularly in Dengzhou,Tanghe,and Xinye areas of Nanyang,a new early-maturity wheat variety,'Wanmai 206',was developed to meet the demand for high-yielding wheat varieties resistant to multiple diseases.This variety was bred using the pedigree method at the Nanyang Academy of Sciences.The maternal parent,Wan120261,was improved to pos-sess dwarfism,large grain size,and overall strong disease resistance.The male parent,'Tianmin 198',exhibited high yield,wide adaptability,and resistance to scab.In 2023,'Wanmai 206'was approved by the Henan Pro-vincial Crop Variety Certification Committee(Yushenmai 20230021).Although'Wanmai 206'is susceptible to stripe rust,powdery mildew,and stripe wilt,it exhibits high susceptibility to leaf rust and scab.'Wanmai 206'has large cutiform grains and good commercial properties.The main characteristics,yield,quality,cultivation techniques,and the application of the new sterile line of'Wanmai 206'were introduced during breeding.
