F3:6 Generasyonunda Pamuk (Gossypium hirsutum L.) Döl Sıralarının Tam ve Kısıtlı Sulama Koşullarında Verim ve Lif Kalite Özelliklerinin Belirlenmesi

Bu çalışma F3:6 generasyonunda tek bitki döl sıralarının tam ve kısıtlı sulama koşullarında verim, verim bileşenleri ve lif kalite özelliklerinin karşılaştırılması amacıyla Adnan Menderes Üniversitesi Ziraat Fakültesi uygulama alanında tam (%100) ve kısıtlı (%50) sulama koşullarında yürütülmüştür. Tam sulama denemesinde 76 tek bitki, kısıtlı sulama da 68 tek bitki, Carizma, Gloria, Carmen, Claudia ve Elsa kontrol çeşitleri ile birlikte Tesadüf Bloklarında Augmented deneme desenine göre, 4 tekerrürlü olarak sıra arası 70 cm, sıra üzeri 20 cm, sıra uzunluğu 12 m olacak şekilde ekilmiştir. Kısıtlı sulama (% 50) koşullarında incelenen tüm özellikler bakımından, tam (% 100) sulama koşullarında ise kütlü pamuk verimi, lif uzunluğu ve lif kopma dayanıklılığı yönünden genotipik farklılığın önemli olduğu saptanmıştır. Bu çalışma sonucunda tek bitki döl sıraları; verim ve lif kalite özellikleri bakımından birlikte değerlendirildiğinde; tam sulama koşullarında, Carmen × Tamcot-22, Carmen × Nazilli-503, Nazilli-503 × DPL-90, BA-308 × Carmen, kısıtlı sulama koşullarında ise Nazilli-503 × Tamcot-22, Carmen × Nazilli-503, Nazilli-503 × Şahin-2000, Carmen × Tamcot-22, BA-308 × Nazilli-503, tek bitki döl sıraları ümit verici döl sıraları olarak saptanmıştır.

Determination of Yield and Fiber Quality Parameters of Cotton (Gossypium hirsutum L.) Progeny Rows at F3:6 Generation Under Full and Deficit Irrigation Conditions

This study was conducted to determine the yield, yield components and fiber quality parameters in a single plant progeny rows at F3:6 generation under the full and deficit irrigation conditions. The experiment was conducted at Adnan Menderes University, Agriculture Faculty in full and deficit conditions.In the full irrigation e×periment, 76 single plants, and in the experiment of deficit irrigation 68 single plants were planted. In addition, planting system was the augmented randomized complete block experimental design by performing 4 replications by 70 cm of row spacing and 12 m of row length. Under deficit irrigation (% 50) genotypic variation was found to be significant for all investigated parameters and, under full irrigation (% 100) condition significant variation was detected for seed cotton yield, fiber length and fiber strength. Based on seed cotton yield and fiber quality parameters of single progeny rows, it was concluded that Carmen × Tamcot-22, Carmen × Nazilli-503, Nazilli-503 × DPL-90, BA-308 × Carmen single progeny rows are promising in the full irrigation conditions, and Nazilli-503 × Tamcot-22, Carmen × Nazilli-503, Nazilli-503 × Şahin 2000, Carmen × Tamcot-22, BA-308 × Nazilli-503 was detected as promising hybrids in the deficit irrigation conditions.
