Özet

Researches on Galia type melon breeding was started in 1995 at Cukurova University, Turkey. The aim of this study was to develop new melon cultivars which belong to Cucumis melo var. cantalupensis group having high yield and quality, suitable for both greenhouse and open field cultivation and also resistant to race 0 and 1 of Fusarium oxysporum f. sp. melonis wilt which are common in Turkey. For this purpose 9 female parental lines were crossed with the donor male parents which are resistant to 0 and 1 races of Fusarium wilt. By this way F-1 hybrids were produced, and after the first backcrosses were done, BC1 genotypes were developed. Haploid embryo inductions and haploid plant productions were obtained by pollination with irradiated pollen. These haploid plants were duplicated by colchisine treatment and dihaploid pure lines were produced. General combination ability and special combination ability tests were conducted and more than 200 F-1 hybrids were developed. These hybrids were tested in open field and greenhouse conditions for many years and Sari F-1 was registered in 2008, Yetisir F-1, Solmaz F-1, Emin F-1 and Yucel F-1 were registered in 2009 by Central Certification and Registration Management of Turkish Ministry of Agriculture. These 5 varieties have some differences concerning their total and early yields, fruit size and TSSC.
