应用各种放射线诱发水稻产生变异创造新类型的研究,国内外已有许多报导。近十几年来,在利用辐射选育水稻早熟、矮秆、高产、优质的新品种方面取得了很大进展。辐射育种的成果也广泛应用于农业生产,如日本用“富士稔”品种经γ射线处理育成早熟、矮秆、高产品种“黎明”,最高亩产1200斤左右,1966年开始推广,1970年已占日本水稻栽培面积的第四位。在菲律宾、孟加拉、以及我国的台湾省利用辐射诱变方法,已选出一批比1R_8。早熟、高产、优质的新品系。我国在1958年开始水稻辐射育种的研究,特别是无产阶级文化大革命以来,由于开展群众性的辐射育种运动,利用比较简陋的设备,在不长的时间内,取得了显著成绩。据初步统计,迄今已选育出30多个水稻新品种,其中“熊岳613”、“津辐1号”、“辐
There have been many reports at home and abroad on the application of various types of radiation to induce new types of rice-induced variation. In recent ten years, great progress has been made in using radiation to breed new varieties of rice that are premature, dwarf, high yield and high quality. The results of radiation breeding are also widely used in agricultural production, such as Japan, “Fuji 稔” varieties by γ-ray treatment of bred early, dwarf, high-yielding varieties of “dawn”, the maximum per mu yield of about 1200 pounds, 1966 began to promote the 1970 Accounting for the fourth place in Japan’s rice cultivation area. In the Philippines, Bangladesh, and Taiwan Province of our country using radiation mutagenesis methods, a number of 1R_8 have been selected. Early maturity, high yield, high quality new line. Since 1958, China began to study the radiation breeding of rice, especially since the Great Proletarian Cultural Revolution, notable progress has been made in the short period of time because of the mass radiation breeding campaign and the use of relatively simple equipment. According to preliminary statistics, up to now, more than 30 new rice varieties have been bred. Among them, “Xiong Yue 613”, “Jin Yun 1”, "
