An image of 13-day-old rice seedlings grown in agar plates in a Conviron growth chamber, (A) image of parent “PI312777” showing different components of seedling root architecture (RSA), (B) the image of parent “PI312777” showing analyzed region in green color loop and bar chart of different color pixels extracted from RSA components based on 0.15 mm diameter class intervals shown on top, (C) an image of parent “Katy” seedling showing analyzed region in green color loop and bar chart of different color pixels extracted from RSA components based on 0.15 mm diameter class intervals shown on top of image. To improve visual clarity in photographs, images shown above were obtained after seedlings had been removed from the agar and rescanned in water.
