Developing varieties adapted to dry conditions is one of the biggest targets for breeders. It is important to use inexpensive spectral sensing methods saving time in variety development. The aim of this study was to select bread wheat genotypes having high grain yield by using spectral sensing methods. Twenty-five bread wheat (Triticum aestivum L.) genotypes were evaluated under rainfed condition at three locations in Central Anatolia Region. The experiment was arranged in randomized complete block design with three replications. Grain yield (GY), Canopy Temperature (CT), Soil Plant Analysis Development (SPAD) and Normalized Difference Vegetation Index (NDVI) values were recorded. GY, CT, SPAD and NDVI were found to be statistically significant in terms of both genotype and environment. The relationship between grain yield and NDVI (R2=0.321**) values was linear. The positive correlation of GY (0.5671**) and SPAD (0.1729*) with NDVI suggest that NDVI can be used as efficient and precise selection criteria for identifying high effiency wheat varieties under rainfed conditions.

This study was carried out in Bahri Dağdaş International Agricultural Research Institute in the growing period of 2014-2015 with 14 bread wheat varieties in rainfed and irrigated growing conditions according to a randomized block trial pattern with 2 replications. Zeleny sedimentation values and bread weight and bread volume traits of bread wheat varieties were investigated. Differences between varieties grown in irrigated and rainfed conditions were evaluated statistically. Zeleny sedimentation values was between 26.00-39.50 ml, bread weight was between 140.20-146.5 g, bread volume was between 340-475 cm3, spesific volume 2.36-3.37 cm3/g in rainfed conditions, while Zeleny sedimentation values was between 31-51 ml, bread weight was between 141.61-149.47 g and bread volume was 367.50-485.00 cm3, spesific volume 2.48-3.38 cm3/g in irrigated conditions. It has been determined that the varieties grown in irrigated conditions give higher value than in rainfed conditions in terms of the examined quality parameters.
