杉木优树选择是表型选择,而表现型值是优树的遗传型和优树所处的环境两者交互作用的结果。为了对杉木树种进行遗传改良,提高杉木树种的生产力和种性,需要对杉木优树子代进行测定。本文通过对42个杉木优树子代测定效应的分析,试图摸索出一套较为简便的;行之有效的分析方法。一、材料和方法试验材料是南京林学院育种研究室和福建省洋口林场在1965年冬,从25～37年生的40多株优树上采穗,所营建的杉木无性系嫁接种子园生产的种子,及其所培育的苗木。本试验所采用的无性系共44个(其中包括2个对照)。对照为优树收集区的混合子代,采用较高水平的对照,是因为本试验的目的是达到优树间的相互比较,优中选优。
The optimal choice of Chinese fir is phenotypic selection, while the phenotypic value is the result of the interaction between the genetic type of the superior tree and the environment in which the superior tree is located. In order to genetically improve the Chinese fir species and improve the productivity and species of the Chinese fir species, it is necessary to determine the progeny of the Chinese fir seedlings. In this paper, we analyzed the determination effect of 42 Chinese fir trees and tried to explore a set of simple and effective analytical methods. Materials and Methods The experimental materials were screened from Nanjing Forestry College Breeding Research Office and Yangkou Forestry Center of Fujian Province in the winter of 1965 from more than 40 excellent trees aged from 25 to 37 years. The clones of Chinese fir clonal grafted seed garden Of the seed, and nurture seedlings. The clones used in this experiment were 44 (including 2 controls). The control is a mixed progeny of the superior tree collection area and a higher level of control is used because the purpose of this experiment is to achieve superior comparison among superior trees,
