Morphological characterization of Amaranth germplasm (original) (raw)

To know about the phenotypic diversity of 42 accessions of amaranth (Amaranthus<br> spp), an experiment was designed in the experimental field of Plant Genetic Resources<br> Centre of BARI, Gazipur during 2016-17. The germplasm were classified on the basis of<br> their use. Among them, 6 gerrmplasm were identified as leaf amaranth and the rest 36 were<br> stem amaranth. Amaranth were also classified as hard (14.29%), medium (4.76%) and soft<br> (80.95%) on the basis of fiber. Qualitative variation was found in branching index, stem and<br> leaf pubescence, leaf shape, leaf margin, terminal inflorescence shape, terminal<br> inflorescence attitude and inflorescence density index. Different color variations were<br> exhibited in stem (green-23.81% and pink or purple-76.19%), leaf pigmentation (entire<br> lamina purple-7.14%, margin and vein pigmented-38.10%, normal green-26.19%, more<br> green shade on purple leaf-9.52%, more ...
