Characterization of American cotton (Gossypium hirsutum L.) genotypes based on morphological characters

Abstract

Fifty genotypes were characterized based on their morphological characters as per DUS guidelines of American cotton viz., hypocotyl pigmentation, leaf shape, leaf colour, leaf pubescence, leaf petiole pigmentation, flower petal colour, flower stigma position, pollen colour, anther filament colouration, plant stem hairiness, plant stem pigmentation, growth habit, plant height, boll colour, boll shape, boll surface, prominence of tip in boll, boll opening and seed fuzz. The genotypes has shown great extent of morphological variability for all the traits observed.
