Introduction performance of three red pear varieties in Hunan
The growth and fruiting habits,adaptability,and fruit quality comparison of three red pear varieties,Meirensu,Hongsucui,and Mantianhong,which introduced into Liuyang area of Hu-nan province,were observed and compared.The results showed that the three varieties could com-plete their annual growth cycle normally in Liuyang area,with Meirensu and Mantianhong growing vigorously,stable fruit setting,and yield of 1 400 kg per 666.7 m2.The growth of Hongsucui was slightly weak,with yield of 1 200 kg per 666.7 m2.The coloring of the three varieties was unstable,with severe rust spots on the fruit skin,which had a significant impact on their coloring.The colo-ring of Mantianhong was relatively better,followed by Meirensu and Hongsucui.All three varieties were mature around mid-September,with the single fruit weight over 300 g,fine flesh,and few stone cells.The soluble solids content was 13.0％～13.8％,and the soluble sugars content was 9.05％～9.36％,all of which were the highest in Meirensu,followed by Mantianhong and Hongsucui.The total acid content was 1.13～1.42 g/kg,with the highest in Mantianhong,and similar in Meir-ensu and Hongsucui.According to comprehensive analysis,all three varieties are not suitable for large-scale development in Hunan.
