Özet:

 In cucumber cultivation, F. oxysporum f. sp. cucumerinum J.H. Owen FOC is an important soil-borne plant pathogenic fungus causing crop loss. Nowadays, the use of grafted seedlings in cucurbits, especially in watermelon, melon and cucumber is effective and widely used method in the control of Fusarium wilt. For rootstock of grafted cucumber seedlings, intraspecific hybrids of Cucurbita maxima Cucurbita moschata and intraspecific hybrids of Cucurbita moschata are commonly used. In this study, first, a gene pool consisting of 49 genotypes of Cucurbita maxima was created for the rootstock breeding program in grafted cucumber production. Subsequently, the resistance levels of these winter squash lines against F. oxysporum f. sp. cucumerinum were determined, and the vegetative growth characteristics of these lines treated with FOC were compared with control plants. Nun 9075 commercial rootstock was used as positive control and Çengelköy cucumber cultivar was used as negative control. As a result of the study, it was determined that 20 genotypes were highly resistant, 23 genotypes were moderately resistant and 5 genotypes were low resistant. It was determined that there were statistically significant differences in plant height, stem diameter, number of leaves, dry root, stem and leaf weights in pathogen-infected and control treatments. As a result of the research, the lines which stood out in terms of both disease resistance and vegetative growth parameters were selected as promising winter squash parents in the breeding programme for the development of new hybrid rootstocks.

 Hıyar yetiştiriciliğinde Fusarium oxysporum f. sp. cucumerinum J.H. Owen FOC ürün kaybına neden olan toprak kökenli önemli bir fungal bitki patojenidir. Günümüzde kabakgillerde özellikle karpuz, kavun ve hıyarda aşılı fide kullanımı Fusarium solgunluğu mücadelesinde etkili ve yaygın kullanılan bir yöntemdir. Aşılı hıyar fidesi için anaç olarak, en çok türler arası kestane kabağı Cucurbita maxima  bal kabağı Cucurbita moschata melezleri ile tür içi bal kabağı melezleri kullanılmaktadır. Bu çalışmada, önce aşılı hıyar üretiminde anaç ıslah programı için 49 kestane kabağı genotipinden oluşan bir gen havuzu oluşturulmuş, daha sonra kestane kabağı hatlarının F. oxysporum f. sp. cucumerinuma karşı dayanıklılık durumlarının belirlenmesi ve FOC ile muamele edilmiş kestane kabağı hatları ile kontrol bitkilerinin vejetatif büyüme özellikleri yönünden incelenmesi amaçlanmıştır. Pozitif kontrol olarak Nun 9075 ticari kabak anacı ve negatif kontrol olarak Çengelköy hıyar çeşidi kullanılmıştır. Araştırma sonucunda, 20 genotipin yüksek düzeyde dayanıklı, 23 genotipin ise orta düzeyde dayanıklı ve 5 genotipin düşük düzeyde dayanıklı olduğu belirlenmiştir. Patojenle enfekteli olan ve kontrol uygulamasında incelenen bitki boyu, gövde çapı, yaprak sayısı, kuru kök, gövde ve yaprak ağırlığı özellikleri yönünden istatistiksel olarak çok önemli düzeyde farklılıklar olduğu saptanmıştır. Araştırma sonucunda; hem hastalık dayanımı hem de vejetatif büyüme parametreleri yönünden öne çıkan hatlar yeni hibrit kabak anaçlarının geliştirilmesine yönelik ıslah programında ümitvar kestane kabağı ebeveynleri olarak seçilmiştir.
