Abstract :In thisstudy, the size and shape properties of twelve different bean cultivars insert ignore into journalissuearticles values(elevenvarieties and a genotype); were determined using image processing on digital photography and the cultivars were groupeddepending on their properties. The highest mean values of geometric diameter, projected area, length, widthand shape factor in the study were determined in the ‘Çayırlı’ genotype. ‘Terzibaba’cultivar, more spherical shape at width orientation compared other cultivars, hadthe lowest value of thickness insert ignore into journalissuearticles values(4.6 mm); and more circular at the widthorientation among the cultivars. The highest mean of thickness insert ignore into journalissuearticles values(6.0 mm); were measuredin ‘Elkoca-05’ and ‘Noyanbey-98’ cultivars. The sphericity mean of ‘Karacaşehir-90’insert ignore into journalissuearticles values(70%); was found higher than those of the other cultivars, while the geometricmean diameter, projected area, length and width values had the lowest mean.’Yunus-90’and ‘Göynük-98’ cultivars had the lowest sphericity mean values of 58.9% and 58.7%,respectively. According to the results of Principal Component Analysis insert ignore into journalissuearticles values(PCA);, themost important variables of the first component were mass, geometric meandiameter, surface area, volume, projected area, equivalent diameter, perimeter andlength. According to the physical properties of bean cultivars ‘Aras-98’, ‘Elkoca-05’,‘Göynük-98’, ‘Noyanbey-98’, ‘Yakutiye-98’ and ‘Yunus-90’ were oblongus; ‘Karacaşehir-90’ and ‘Önceler-98’were ellipticus; ‘Akman-98’, ‘Kantar-05’and ‘Terzibaba’ were subcompressusand ‘Çayırlı’ genotype was compressus.
