5. SONUÇLAR VE ÖNERĠLER
5.2 Öneriler
Ülkemizde çerezlik kabak yetiştiriciliğinde en çok kullanılan, Hatun Tırnağı, Çerçevelik gibi yerel çeşitler kurak şartlardan çok fazla etkilenmiş ve düşük verimli çeşitler olarak belirlenmiştir. Bu sebeple, sulama yapılmadan yetiştiricilik yapılacak olan alanlarda özellikle Mert Bey F1 hibrit çeşidinin tercih edilmesi önerilmektedir. Yaptığımız çalışmanın ve genetik havuzumuzun değerini ortaya koyan 9, 34, 40, 32 ve 36 numaralı saf hatlar kurak şartlarda ticari çeşitlerden ve diğer genotiplerden daha üstün verime sahip olmuşlardır. Bu genotiplerin ileride yapılması muhtemel “kuraklığa tolerant çerezlik kabak ıslahı” programlarında ebeveyn olarak kullanılmasıyla hem ülkemize ait yerel materyaller korunacak hem de kurak bölgelerde birim alandan elde edilen verimi artıracak yeni yerli hibrit çeşitlerin geliştirilmesine katkı sağlanacaktır.
Çalışma sonuçları arazi şartlarında elde edilmiştir ve genetik havuz hakkında önemli bilgiler edinmemize yardımcı olmuştur. Elde edilen sonuçlar ışığında, genotiplerin gen haritalarının moleküler yöntemlerle belirlenerek kuraklıkla olan genetik ilişkilerin ortaya koyulması kuraklığa tolerantlılığın belirlenmesi ile daha net sonuçlara ulaşılacaktır. Elde etmiş olduğumuz bu geniş gen havuzundaki mevcut genotiplerin daha sonraki yapılacak çalışmalarda diğer abiotik stres şartlarındaki performanslarının belirlenmesi, üstün nitelikli F1 hibrit çeşit ıslahında önemli bilgiler edinilmesine yardımcı olacaktır. İç anadolu Bölgesi'nde çerezlik kabak tarımı yoğun bir şekilde yapılmaktadır. Bu bölgelerde yapılacak olansu-verim ilişkileri çalışmalarında, özellikle çerezlik kabağın belli gelişme dönemlerinde uygulanacak farklı su kısıtları ile uygun sulama programlarının oluşturulması gerekmektedir. Böylece su kaynakları kısıtlı olan Konya gibi kurak ve yarı-kurak alanlarda suyun etkin kullanılması sağlanacak ve sulama giderleri azaltılabilecektir.
