为了提高巴西橡胶的产量和抗性,我国橡胶育种工作者除了参与国际橡胶发展委员会到橡胶树的故乡——巴西亚马逊河流域去寻找高产的野生种质资源外,各地还开展了单倍体育种、组织培养、理化诱变、选缘杂交等工作,取得了一些可喜的成绩。但是关于巴西橡胶的细胞学及细胞遗传学方面研究的报道却很少见。两年来,我们对巴西橡胶小孢子母细胞减数分
In order to improve the yield and resistance of Brazil’s rubber, in addition to participating in the International Rubber Development Committee to the hometown of Rubber Tree - Brazil Amazon River to find high-yielding wild germplasm resources, the rubber breeders in our country also carried out haploid breeding, Tissue culture, physical and chemical mutagenesis, selection hybridization work, made some gratifying achievements. However, reports on the studies of cytology and cytogenetics of Brazilian rubber are rare. In the past two years, we have scored down on the Brazilian rubber microspore mother cells
