安苗1号母树经62/63、66/67和67/68三个严冬考验选出的,其初生代无性系是我场试验山北坡19个品系抗性系比试验中最好的品系,该无性系于69年春定植,经过73/74和75/76两个严冬的考验,寒害都在1级以下（附表）,比天任31——45轻1.33级,茎干茎基未发生爆皮流胶或严重烂脚（见下表）。至78年5月底,5株平均茎围45.2厘米,第一刈年自5月18日至11月9日共割75刀（其中16刀加电石刺激）,平均每株年产干胶1.57公斤。绝对产量20.973克/株次,相对产量0.953克。
The seedlings of Anmiai No.1 were selected by the three harsh tests of 62/63, 66/67 and 67/68. The first generation of clones was the best strain in the resistance ratio test of 19 lines on the northern slope of the field , The clones in the spring of 69 colonization, after 73/74 and 75/76 two severe winter test, cold damage are less than 1 (Schedule), light than any light 31--45 grade 1.33, stem stem base Cracking gel or serious rotten feet (see table below). By the end of May, 78, the average stem diameter of the five plants was 45.2 cm. In the first harvesting year, 75 knives (including 16 knives plus calcium carbide stimulation) were cut from May 18 to November 9 in the first harvest year, with an average annual dry weight of 1.57 kg . The absolute yield of 20.973 g / strain, the relative yield of 0.953 grams.
