tailieunhanh - Assessment of response to drought stress of chickpea (Cicer arietinum L.) lines under rainfed conditions

Totally sixty four chickpea lines were grown for assesment of response to drought stress in the stress and non-stress environments under rainfed conditions. The seed yield of the lines when grown under the non-stress condition increased at a rate of 53% over the in stress condition. | Tr.

İlhan ÇAĞIRGAN Department of Field Crops, Faculty of Agriculture, Akdeniz University, Antalya-TURKEY Received: Abstract: Totally sixty four chickpea lines were grown for assesment of response to drought stress in the stress and non-stress environments under rainfed conditions. The seed yield of the lines when grown under the non-stress condition increased at a rate of 53% over the in stress condition. The line, FLIP 92-154C, was determinated as the best tolerant line to drought stress environment under the field condition. Also, seed yield strongly correlated with biological yield, harvest index, mean productivity, tolerance to drought stress and drought susceptibility index in the stress environment. Yağmurla Beslenen Koşullar Altında Nohut (Cicer arietinum L.) Hatlarının Kuraklığa Tepkilerinin Belirlenmesi Özet: Toplam altmışdört nohut hattı, kuraklık stresine tepkilerinin belirlenmesi amacıyla yağmurla beslenen koşullar altında kuraklık stresi ve kuraklık stresi olmayan çevrelerde yetiştirilmişlerdir. Kuraklık stresi olmayan koşullar altında yetiştirilen hatların dene verimleri kuraklık stresi olan kuşallardakilere göre %53 oranında artmıştır. FLIP 92-154C hattı, tarla koşullarında kuraklık stresi çevreleri için kuraklığa en tolerant hat olarak belirlenmiştir. Ayrıca, kuraklık stresi olan çevrelerde dane verimi ile biyolojik verim, hasat indeksi, ortalama verimlilik, kuraklık stresine tolerans ve kuraklığa duyarlılık indeksi arasında önemli ilişki bulunmuştur. Introduction In Semi-Arid Tropics (SAT) and Mediterranean environments, especially in West Asia and North Africa (WANA), the major abiotic constraints are drought and high temperature stresses because spring crops, with the exceptions of faba bean (Vicia faba L.), pea (Pisum sativum L.) and lentil (Lens .
