Evaluation and identification on botanical characters and quality characters of forage ramie germplasm resources

Botanical characters such as plant height, blade tip, pistil color, leaf shape, leaf color, serrated leaf margin, stipule of 120 forage ramie were evaluated in ramie germplasm repository of Hunan Agricultural University, and the nutritional composition of 20 ramie varieties with higher biological production were determined. The results showed that various ramie resources botany characters were different. According to the different characters, the classifications were that height was divided into four categories, leaf tip was divided into four categories, pistil color was divided into six categories, leaf shape was divided into three categories, leaf color was divided into four categories, serrated leaf margin was divided into four categories, stipules was divided into four categories. Crude protein content of leaf was generally high in ramie, the majority of varieties were over 19%, the highest crude protein content was 23.69%, and the cellulose content in majority of varieties was about 20%, they were suitable for the forage grass.
