Kısıntılı ve Tam Sulama Koşullarında Verim ve Lif Kalitesi Bakımından Üstün İleri Pamuk (Gossypium hirsutum L.) Hatlarının Seleksiyonu.

This study was carried out at Aydin Adnan Menderes University, Agriculture Faculty Field Crops Experiment fields under drip irrigation system to investigate the response of cotton hybrid populations to water stress in F8 generations in accordance with Augmented randomized complete block design. Each lines and five control varieties (Gloria, Flash, DP332, Candia and Claudia) were planted one row and 12 m long under irrigated (%100: full irrigation) and water stress (%50: deficit irrigation) conditions. The result of the study revealed that in F8 generation; Carmen x Nazilli-503 (line no: 1), DPL-90 x Tamcot-22 (line no: 10), BA-308 x Carmen (line no: 38), DPL-90 x Tamcot-22 (line no: 66) and ST-373 x DPL-90 (line no: 72) cotton advanced lines exhibited the highest seed cotton yield and fiber quality. As for under deficit water stress condition Nazilli-503 x Tamcot-22 (line no: 6), ST-373 x Carmen (line no: 23), BA-308 x Nazilli-503 (line no: 47), BA-308 x Carmen (line no: 72), and Ş-2000 x Tamcot-22 (line no: 90) were found to be drought resistant or tolerant hybrid populations. In order to register new cotton varieties with high yield and fiber quality suitable for full and limited irrigation conditions, selected cotton lines will be tested for variety yield tests.
