Hybridization potential and genetic influence of parental varieties on fruit size and set rate in Gleditsia sinensis.

ABSTRACT: Gleditsia sinensis is a dioecious perennial tree, with its fruit size directly impacting its economic value. Investigating the feasibility of hybridization between different Gleditsia varieties and the influence of parentage on fruit size is crucial. In this study, we compared the pollen viability of Gleditsia sinensis, Gleditsia japonica var. delavayi (G. delavayi), Gleditsia japonica and Gleditsia fera under long-term storage, and explored the feasibility of intraspecific and interspecific hybridization of Gleditsia sinensis. We also evaluated the genetic characteristics of parentage on the fruit size and fruit set rate of Gleditsia sinensis. The results indicated that dry storage at -80 °C is suitable for the long-term preservation of pollen for most Gleditsia varieties. Interspecific h
