The Differences Analysis Of Qualities Of 'Ruiyang' And 'Ruixue' Apple Varieties In Different Production Areas

‘Ruiyang' and ‘Ruixue' are two new late-maturing apple varieties,which were hybrid bred by Northwest A&F University.In recent years,the research shows that they have excellent qualities and relatively good cultivation characteristics.In order to explore the suitable cultivation areas of these two new varieties and speed up the promotion,this experiment selected different locations in the four major apple producing areas of the whole country.The main quality characters of the fruits were compared and analyzed in2018,in order to provide a basis for the promotion of the two new varieties,and the following main results achieved:Through the analysis of the main quality differences of sampling bagging “Ruiyang”in Hebei,Shanxi,Shaanxi and Gansu provinces,it is found that ‘Ruiyang' has better coloration at 832 m above altitude,and it is greatly affected by the climate at low altitude.‘Ruiyang' is more adaptable at high altitudes and comprehensive quality performance is better.By analyzing the sampling of 'Ruiyang' without bagging in the five provinces of Shandong,Jiangsu,Henan,Hebei and Gansu,the inherent quality of 'Ruiyang' was better,but the color performance was ordinary.Therefore,'Ruiyang' is suitable for planting in the range of 832 m above sea level,N35°13'~N35°39';E107°41'~109°40'.Through the analysis of the main quality differences of the sampling bagging 'Ruixue'from the four provinces of Hebei,Shanxi,Shaanxi and Gansu,it is found that in the altitude range from 303 m to 1350 m,‘Ruixue' can show a better quality and can be popularized and planted.Sampling without bagging from the six provinces of Shandong,Henan,Hebei,Yunnan,Gansu and Shaanxi ‘Ruixue' had good quality and good performance.‘Ruixue' is suitable for planting in the range of 303m-1350 m,N27°16?~38°52?;E103°37?~114°51?.It is found that the comprehensive quality of the red variety 'Ruiyang' is most similar to 'Fuji',however,'Ruixue',as the yellow variety,the inherent quality is better than 'Fuji'and also has good storage characteristics.Through the comparative analysis of three varieties of 'Ruiyang','Ruixue' and 'Fuji' in Baoding,Yuncheng,Yongshou,Tongchuan and Xunyi.However,in terms of cultivation management,‘Ruiyang' and ‘Ruixue' are easier to cultivate than ‘Fuji'.
