在毛主席革命路线指引下,我场和全国各地一样开展对水稻杂种优势利用的研究。经过几年的努力,育成了早粳“南台粳”雄性不育系及其相应的保持系。并通过测交筛选和人工制造恢复系,选出了部分有恢复力的品种和品系,完成了“三系”配套。通过秈粳杂种优势的鉴定,使我们认识到秈粳杂交一代能够充分地发挥秈粳稻各自的优点,有较明显的杂种优势。目前,我们正在继续加速对秈粳型不育系“南台粳”繁殖、制种及杂种优势利用的研究和探讨。以下分几点略谈我们的体会:
Under the guidance of Chairman Mao’s revolutionary line, we have conducted researches on the utilization of rice heterosis as well as the rest of the country. After several years of hard work, bred early japonica “southern Taiwan japonica” male sterile line and its corresponding maintainer line. Through selecting and recovering lines by screening and artificial selection, some varieties and lines with restoring force were selected, and the matching of “three lines” was completed. Through the identification of indica-japonica heterosis, we recognize that indica-japonica hybrid generation can give full play to the advantages of indica and japonica, have obvious heterosis. At present, we are continuing to speed up the research and discussion on the breeding, seed production and heterosis utilization of indica-japonica CMS lines “Nantai Japonica”. The following points points about our experience:
