Abstract

‘Melon Chukanbohon Nou 5 Go’, a melon parental line with resistance to Cucurbit chlorotic yellows virus (CCYV), was developed from a cross between the CCYV-resistant I-10 and the CCYV-susceptible ‘Earl’s Favorite Harukei No. 3’. ‘Melon Chukanbohon Nou 5 Go’ presents milder symptoms than susceptible cultivars. This resistance is controlled by one recessive gene. The simple sequence repeat (SSR) marker ECM230 on chromosome 1 was selected and this marker can be used for selection in CCYV-resistance breeding in melon. The internode and petiole lengths of ‘Melon Chukanbohon Nou 5 Go’ are longer than those of ‘Earl’s Favorite Harukei No. 3’. The fruit shape is oblate and the fruit matures approximately 45 days after fl owering. The fruit contains grooves and a pistil scar is larger than that of ‘Earl’s Favorite Harukei No. 3’. The strength of the peduncle attachment is weak, and the Brix value of fl esh is approximately 11°.
