黄麻属园果种和长果种这两个种所生产的韧皮纤维在植物纤维中的重要性仅次于棉花。其最多的产量是在恒河至布拉马普特拉河(雅鲁藏布江下游)三角洲,该地园果种多于长果种。一、细胞分类的背景黄麻属约有40个种,分布在泛热带,多数的种,包括栽培的,其染色体数目为2n=2x=14。并且知道一些种为四倍体(2n=28)。关于野生种细胞分类的亲缘关系未见报导。两个栽培种可以杂交,但困难很大。Swaminathan等(1961)报导了杂种的染色体易位,Datta(1958)检出两个种间染色体形态有相当的差异。
The importance of bast fiber produced by the two species of jute, both of the garden fruit and the long fruit, in plant fiber is second only to that of cotton. Its largest production is in the delta from the Ganges to Brahmaputra (downstream of the Yarlung Zangbo River), where there are more orchards than long-fruit cultivars. First, the background of cell classification Jute belongs to about 40 species, located in the Pantropical, most species, including cultivated, the number of chromosomes 2n = 2x = 14. And some species are known as tetraploids (2n = 28). No relationship has been reported regarding the classification of wild species. Two cultivars can be crossed, but difficult. Swaminathan et al. (1961) reported hybrid chromosomal translocations, and Datta (1958) detected a considerable difference in chromosomal morphology between the two species.
