从国外31个国家和地区引进红麻品种325份,据其形态特征可分为18个表型,其中12个属于新引进的表型,以首次搜集到的野生资源尤为珍贵。对其中20份高产品种研究表明:全杆产量和纤维产量以 BG52—135最高,分别比对照青皮3号增产14.56%和11.2%,其次为台农一号,EV71等,增产10—7%。纸浆品质好、出浆得率高、木纤维较长适于造纸用的品种为 BG52—135,次为 EV71。抗根结线虫病较强的品种为 J—1—113。高抗红麻炭疽病的有85—224,85—133等。文中还详细论述了引进资源的其它特征及生长发育特性等。 325 kenaf varieties were introduced from 31 countries and regions in foreign countries. According to their morphological characteristics, they can be divided into 18 phenotypes, of which 12 belong to the newly introduced phenotype. The wild resources collected for the first time are especially valuable. The research on 20 high-yielding cultivars showed that full-barrow yield and fiber yield were the highest with BG52-135, which increased by 14.56% and 11.2% respectively compared with that of the control Qingpi3, followed by TaiNong-1 and EV71, with a yield increase of 10-7%. Pulp quality is good, the pulp yield is high, longer wood fiber for the paper used for the species BG52-135, times for the EV71. Root-knot nematodes stronger varieties J-1-113. High resistance to anthracnose have 85-224,85-133 and so on. The article also discusses in detail the introduction of other characteristics of resources and growth and development characteristics.
