早秈稻蕪农一号从开始选育到現在,已有五年。先后在各地經过多次試驗,增产比較显著,得到好評,决定1963年在蕪湖血区开始大面积示范推广。有必要将选育經过与有关試驗研究資料加以整理,以供参考。一、选育经过蕪农一号是1957年从本所保存的至德县地方品种“早谷”(品种区編号一○二)留种田內选来的一棵单株,包括分蘗共得四穗。当时表現抽穗期較早,植株比原种約矮十厘米,茎稈較粗壮,穗着粒密。四穗共收种子五百余粒,其中主惩一百七十二粒。为了加速繁殖种子,当年又将全部种子作为晚稻直播。7月31月播种,10月16日成熟,共收种子約零点七斤。1958 Five years has passed since the early indica rice Wuhuong No.1 was bred to the present. Has repeatedly tested in various places, a significant increase in production, has been well received, decided in 1963 in Wuhu blood began large-scale demonstration and promotion. It is necessary to organize the breeding and related experimental research materials for reference. I. Breeding After Wuhu-1 is a single plant selected from the “Zaogu” local variety “Zao Valley” (breed area code 102) preserved in 1957 by the parent, including the total number of tillers Four spikes. At that time, the performance heading stage earlier, the plant about ten centimeters shorter than the original species, stalks thicker, spike grain density. Four ears received a total of five hundred seeds, of which the main punish seventy-two tablets. In order to speed up the breeding of seeds, then all the seeds will be broadcast as late rice. July 31 planting, mature on October 16, received a total of about seven pounds seed. 1958
