在通常情况下,高等植物种间或属间远缘杂交,由于不亲和性,致使胚在早期败育或发育不良。因此,一般不易得到杂种。为了克服远缘杂交不亲和的障碍,国内外许多研究者应用胚珠和胚培养技术,成功地得到多种植物的种间和属间杂种植株。为了获得黄麻长、圆果种,红麻与木槿属的种间杂种,我们于一九七八年开始,三年来进行了黄麻、红麻及其种间杂种胚珠培养的探索。一、材料与方法:供试材料有黄麻属的圆果种闽麻407、长果
Under normal circumstances, distant hybridization between higher species or between species, due to incompatibility, resulting in early embryo abortion or dysplasia. Therefore, it is generally not easy to get hybrids. In order to overcome the obstacle of distant hybridization incompatibility, many domestic and foreign researchers successfully obtained the interspecific and interspecific hybrid plants of many plants by using ovule and embryo culture techniques. In order to obtain interspecific hybrids of jute, round fruit, kenaf and hibiscus, we started the exploration of ovule culture of jute, kenaf and their interspecific hybrids in 1978, three years ago. First, the material and methods: The test materials are jute fruit round fruit Minma 407, fruit
