| Abstract: | The construction of Larix olgensis 1.5 generation seed orchard derived from 2010 in Xiyang forest tree seed or-chard of Yongji County by taking to fix the stock firstly and then to grafting .The material was 88 excellent clones .There were 47 clones which were adversely selected from the first generation seed orchard production area and 41 clones from ex-cellent forest of provenance natural forest .The total construction area was 20 hm2 , which was divided into 4 major areas, 18 plots.The clones were configured by applying completely randomized design by taking plot as unit .It provided condition for complete heteromorphosis mating . |
