“包选二号”是玉林地区农科所1968年从“包胎白”选育出来的晚稻品种。它具有适应性广、产量稳定、米质好、抗性较强等优点。据1980—1981年菲律宾国际水稻研究所对“包选二号”及其姐妹系“包胎矮”的研究,认为这两个品种的“烹调质量设好”(引自国际水稻研究所1981年12月《中国两个水稻品种抗性的研究》),且对大青叶蝉、草绿色矮化病等8虫4病具有抗性。正由于“包选二号”具有上述优点,所以,我地区从1970年开始推广十多年来,种植面积占全地区晚稻面积60—70%,最高达80%以上。相邻的梧州、钦州、南宁等地 “Package selection on the 2nd” is Yulin Prefecture Agricultural Institute in 1968 from “Baotai white” breed late rice varieties. It has wide adaptability, stable output, good quality rice, strong resistance and so on. According to the research conducted by the International Rice Research Institute of the Philippines from 1980 to 1981 on “Bao Xuan No.2” and its sister line, “Baotou Dwarf”, the “quality of cooking” of these two varieties is considered (cited in International Rice Research Institute, 1981 December “China two rice varieties resistance”), and the green leafhopper, grass green dwarf disease and other 8 insect 4 disease resistance. Due to the above advantages of “Package Selection II”, the area planted in the region has been growing by 60-70% and up to 80% or more in the whole region since late 1970s.
