摘 要 ：17份红麻稀有材料的研究发现叶、苞片、萼片、花冠、蒴果和种子等形态特征变异丰富。细胞学研究表明，染色体数均为2n=36；栽培材料随休有普通型、较大型和特大型，野生材料均为普通型；野生材料染色体结构较栽培材料对称。野生材料与常规品种杂交，座果率变幅35-50%，结实率3.2-17%，均明显低于对照（分别为69%和30%），表明

Abstract:17 entries of cultivated and wild types of rare kenaf germplasms were studied to determine their taxonomical position. Rich morphological variations in leafblades, bractoles, sepals, flowers, capsule and seed were observed. Cytological study revealed that the chromosome number of all 17 entries were
