乌兰察布市19个马铃薯品种适应性评价
Adaptability Evaluation of 19 Potato Varieties in Ulanqab
摘要
Abstract
In response to the rapid demand for new potato varieties and the contradiction between the shift of potato cultivation from"numerous and disorderly"to specialization,taking into account varieties for different uses such as fresh consumption and processing(starch,whole flour),evaluation experiments,including 19 varieties,were conducted to screen superior new varieties suitable for Ulanqab's ecological and industrial conditions.A comprehensive ranking of varieties was conducted to assess their promotion value,through a systematic evaluation of their basic traits(flesh and skin color,and tuber shape),quality(vitamin C,reducing sugar,and dry matter contents),yield,marketable tuber percentage,and tuber-producing ability of individual plants to produce tubers,combined with principal component analysis.Obvious phenotypic diversity was observed among the 19 varieties.The predominant flesh colors were medium yellow and yellow across 11 varieties,accounting for 57.90%,and the most common tuber shapes were oval and elliptical(57.90%).The tuber color was mainly yellow,11 varieties,accounting for 57.90%.In terms of the growth period,there were 10 medium maturing potato varieties,accounting for 52.63%,with very early maturing and late maturing varieties being absent.Considering yield and marketable tuber percentage as well as production reality,'Xisen 1'and'Zhongjia 7'were the best choice,while'Xisen 6'and'Jingzhangshu 3'were also taken into account.The demands of fresh consumption and processing were met by the varieties performing well in terms of nutritional quality,marketable tuber percentage,and adaptability.In terms of potato chip processing,varieties with low reducing sugar content and high yield are recom-mended,such as'Atlantic'and'Menghua 2'.For French fries processing,'Xisen 6','Huasong 7'and'Russet Burbank'are recommended.In terms of whole powder processing,choose'Zhongjia 11'and'Huasheng 7'.The flexibility of the planting system can be enhanced by optimizing the structure of mid-late maturing varieties,retaining existing advantageous mid-late maturing varieties,such as'Jingzhangshu 3',with a yield of 60.55 t/ha and marketable tuber percentage close to 90%.Very early maturing varieties should also be introduced to fill market gaps.These results provide a solid foundation for the sustained and healthy development of the potato industry in Ulanqab.关键词
