Investigation of Punica granatum L.Germplasm Resources in Binchuan and Comparative Analysis of Major Fruit Qualities

[Objective] This study aimed to provide a basis for enriching the Punica granatum L. germplasm resources through investigating Punica granatum L. vari- eties in Binchuan. [Method] In this study, biological traits of Punica granatum L. vari- eties in Binchuan （including two local varieties-＇Binchuan Red Coat＇ and ＇Binchuan Green Coat＇, ＇Cyan Coat and Soft Seeds＇ and ＇Little Red Coat＇ introduced from Huili, Sichuan, ＇Acid Pomegranate＇ introduced from Shandong Province and ＂Ma Pomegranate＂ from Fengqiu, Henan） were investigated and their major fruit qualities were also analyzed. [Result] ＂Cyan Coat and Soft Seeds＇ and ＂Ma Pomegranate＇ grew well with good fruit quality, which adapted well to the climate and environment in Binchuan; ＂Little Red Coat＇ showed average performance in growth and major fruit qualities with inferior flavour; ＂Binchuan Red Coat＇ and ＇Binchuan Green Coat＇ also showed average performance in major fruit qualities and and inferior flavour; ＇Acid Pomegranate＇ grew while was inferior in flavour. [Conclusion] This study pro- vides references for presenting the directions for studies of P. granatum L. germplasm resources and determining the genetic relationship among germplasm resources, as well as breeding, introduction and cultivation of P. granatum L., further providing a variety basis for pomegranate production.
