Developing varieties adapted to dry conditions is one of the biggest targets for breeders. It important use inexpensive spectral sensing methods saving time in variety development. The aim this study was select bread wheat genotypes having high grain yield by using methods. Twenty-five (Triticum aestivum L.) were evaluated under rainfed condition at three locations Central Anatolia Region. expe...

This study assesses the vulnerability of Bulgarian agriculture to drought using the WINISAREG model and seasonal standard precipitation index SPI(2) for the period 1951-2004. This model was previously validated for maize on soils of different water holding capacity (TAW) in various locations. Simulations are performed for Plovdiv, Stara Zagora and Sofia. Results relative to Plovdiv show that in...

To determine root growth and grain yield of winter wheat (Triticum aestivum L) under moderate drought stress, a nursery experiment and a field trial were conducted with or without water stress using three representative cultivars released in different years: CW134 (old landrace), CH58 (modern cultivar) and CH1 (new release). In the nursery experiment, plants were grown in soil-filled rhizoboxes...
