在无产阶级文化大革命与批林批孔强劲东风的推动下,我国对水稻杂种优势的利用在生产上已取得显著成果。杂种一代在稳产高产方面表现甚为突出,在生产上已开始较大面积的应用,为水稻增产开创了一条途径。水稻不育系确定后,在选配具有最优生产力的父本(恢复系)方面,一般需靠大量的杂交组合和田间实验,才能取得成效。例如,湖南省为二九南不育系选配具有恢复能 Driven by the proletarian cultural revolution and the vigorous easterlies of the proletariat, the utilization of rice heterosis in our country has achieved remarkable results in production. The hybrid generation has shown outstanding performance in terms of stable and high yield and has begun to use large-scale production in production, opening up a way for rice yield increase. After the male sterility line of rice has been identified, in order to select the male parent (restorer line) with optimal productivity, it usually takes a large number of cross combinations and field experiments to obtain results. For example, Hunan Province for 29 male sterile line with recovery energy
