Interspecific Hybridization of Durian

Abstract

The investigation of interspeciffic hybridzation of Durian was conducted at Chanthaburi Horticultural Research Center during February 1988 - Feburuary 1992. Hybridization between the cultivars and the orther species of Durian were done with 805 flowers from 25 crosses during 1988 - 1991. Mostly, all crosses had low percentage of fruit seeting except some crosses such as the Durio zibethinus via "Chanee" crossed with Durio mansoni via "charian" and the Durio mansoni via "charian" crossed with Durio zibethinus via "Monthong", "Kradumthong", "Kanyao" and "Kob Pikulthong" which some pollinated fruits could develop until harvesting. For 1992, 963 flowers from 20 crosses were crossed and found that the hybrid fruits from the Durio mansoni via "charian" crossed with Durio zibethinus via "Chanee", "Kanyao", "Monthong", "Kradumthong", and "Kob Pikulthong" and the Durio kutejensis crossed with Durio zibethinus via "Kanyao" could develop until harvesting. These F1 hybrid seeds were planted to produce F1 hybrid plants.
