It was concluded that a selection for kernels per spike should be effective in cross-1 (6 x Gönen) but for spike length and kernels per spikelet in other cross, the success of selection which may be practised in advanced generations should depend on the type ofepistatic gene effect.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Generation means of parental (P] and P2) and segregating populations (Fj, Fj and F4) were used to estimate gene effects for grain yield per spike and other spike characters in two spring wheat (T. asetivum L.) crosses.
📊
Key Findings & Data:Results of analyses for generation means indicated that additive effects for all except spikelets per spike in cross-1 (6 x Gönen) and dominance component for all but kernels per spike and kernels per spikelet in cross-2 (22 x Gönen) were significant.

Abstract

Generation means of parental (P] and P2) and segregating populations (Fj, Fj and F4) were used to estimate gene effects for grain yield per spike and other spike characters in two spring wheat (T. asetivum L.) crosses. Results of analyses for generation means indicated that additive effects for all except spikelets per spike in cross-1 (6 x Gönen) and dominance component for all but kernels per spike and kernels per spikelet in cross-2 (22 x Gönen) were significant. Epistasis was detected for spike characters studied in both crosses. It was concluded that a selection for kernels per spike should be effective in cross-1 (6 x Gönen) but for spike length and kernels per spikelet in other cross, the success of selection which may be practised in advanced generations should depend on the type ofepistatic gene effect.

Özet

İki ekmeklik buğday (T. aestivum L) melezinde ebeveynler (Pj ve 1'2> ve açılan generasyonlarin (F2, Fj ve F4) ortalama değerleri kullanılarak başak dane vehmi ve diğer başak özelliklerine ilişkin gen etkileri tahmin edilmiştir. Generasyon ortalamaları analizlerinden elde edilen bulgular ; Melez-l (6 x Gönen)' de başakta başakcık sayısı dışında diğer özellikler için eklemeli etkilerin, Melez-2 (22 x Gönen)' de de başakta ve başakçıkta dane sayıları dışında dominanttık gen etkilerinin her iki melezde generasyon ortalainürinü önemli katkılarının bulunduğunu ortaya kuymuşUü. iki iitelez populasyondu do tüm başak özelliklerinin kalıtımlarında epistasinin söz konusu olduğu belirlenmiştir. Melez-l (6 x Gönen )' de başakta dane sayısı için yapılacak bir seçimin etkili olabileceği; diğer melezde ise başak uzunluğu ve başakçıkta dane sayısı yönünden ileri generasyonlarda uygulanacak bir seçimde başarının etkili epistasi tipine bağlı olacağı sonucuna varılmıştır.
