Özet:

 This study aimed to determine the effects of heterosis, heterobeltiosis and dominance on the inheritance of agronomic traits in popcorn. The study was carried out for two years 2018-2019 under ecological conditions of Samsun province. A total of 32 inbred popcorn lines were crossed with two tester lines i.e., P206 and HP7211 during 1st year and 64 hybrids were obtained. Yield trial was carried out according to the 8  8 partially balanced Lattice trial design with 2 replications during 2nd year. Yield and yield components of each genotype were determined, hybrid vigor of the hybrids and general combaning abilities of the parents were examined. Heterosis, heterobeltiosis, and general combaning abilities occurred positively and negatively in all traits. Heterosis rates for grain yield trait were between -11.33 and 178.05, whereas heterosis rates for bursting volume trait were between -0.9 and 69.9. Heterobeltiosis rates ranged between -15.85 and 163.86 for grain yield and -14.4 and 69.1 for bursting volume. Overdominance and partial dominance genes were effective in the inheritance of the examined traits. It was also determined that TCK129, TCK 135, TCK136 and TCK144 lines can be used as genitor lines due to their high grain yield and average bursting volume. These results indicate that new commercial popcorn hybrids which can be planted in Türkiye can be developed in a short time.

 Bu çalışmada, patlamış mısırın agronomik özelliklerinin kalıtımında heterosis, heterobeltiosis ve baskınlığın etkilerinin belirlenmesi amaçlanmıştır. Çalışma, Samsun ekolojik koşullarında iki yıl 2018-2019 süreyle yürütülmüştür. Çalışmanın birinci yılında 32 adet kendilenmiş patlamış mısır hattı, iki test hattı P206 ve HP7211 ile melezlenmiş ve 64 adet melez elde edilmiştir. İkinci yılda ise verim denemesi, 8  8 kısmi dengeli Latis deneme desenine göre 2 tekrarlamalı olarak yürütülmüştür. Denemede her genotipe ait verim ve verim öğeleri belirlenmiş, melezlerin melez gücü ve ebeveynlerin genel kombinasyon uyumları incelenmiştir. Heterosis, heterobeltiosis, genel kombinasyon uyumları tüm özelliklerde olumlu ve olumsuz yönde ortaya çıkmıştır. Denemede tane verimi özelliğinde heterozis oranları-11.33 ile 178.05 aralığında, patlama hacmi özelliğinde heterozis oranları-0.9 ile 69.9 aralığında belirlenmiştir. Heterobeltiosis oranları tane verimi özelliğinde-15.85 ile 163.86 aralığında, patlama hacmi özelliğinde ise-14.4 ile 69.1 aralığında ölçülmüştür. Çalışmada incelenen özelliklerin kalıtımınında, aşırı baskınlık ve kısmi baskınlık genlerinin etkili olduğu belirlenmiştir. Ayrıca yüksek tane verimi ve ortalama patlama hacmi kapasiteleri nedeniyle TCK129, TCK 135, TCK136 ve TCK144 hatlarının genitor hatları olarak kullanılabileceği belirlenmiştir. Bu sonuçlar kısa sürede Türkiyede ekilebilecek yeni ticari patlamış mısır melezlerinin elde edilebileceğini göstermektedir.
