就对柴达木盆地自然分布的野生罗布白麻进行群落优良居群选择,选定在同一龄组中,优良居群的标准为:群落居群平均株高十1.5倍群落居群株高标准差。按此标准在野生群落中选出4个优良居群。对罗布白麻不同种源1年生温棚播种苗进行超级苗选择,超级苗的标准为:平均苗高十3倍苗高标准差。分别选出青海渔水河罗布白麻超级苗31株、新疆普惠罗布白麻超级苗30株、青海托拉海罗布白麻超级苗31株。
The optimal selection for the community of wild Robusta flax seedlings in the Qaidam basin was based on the criteria of elite population in the same age group: difference. According to this standard, four excellent populations were selected from the wild communities. The seedlings of 1-year-old greenhouse seedlings from different provenances of Luobu Ma were selected for super seedlings. The standard of super seedling was as follows: average height of seedlings was 10 times higher than that of normal seedlings. Respectively, selected 31 superbreds of Luobu Ma of the Yushuihe River in Qinghai Province, 30 super-breeds of Pomarobu and White Superba in Xinjiang, and 31 super-breeds of the Torah-Haibu White Herb in Qinghai.
