我们的多点子代测定的研究从1976年开始,于1978年结束。本研究的结果表明:家系×地点的方差分量基值的高百分比率(10～20％),证实了杉木的GEI是非常显著的。 在本研究中根据遗传型的稳定性,多点子代测定被研究的家系可分为三种类型,即“速生稳定型”(占20～25％)、“变化型”(50～60％)、“慢生型”(20～25％)。 我们的研究证实:杉木家系当半同胞子代在三个不同地区测定时(具有共同遗传对照),其家系均值的稳定性值是0.691;然而,当在两个不同地区测定时,共家系均值的稳定性在0.533以上。最后,当全同胞子代在两个不同地区测定时,其家系均值稳定性值接近0.52。
Our multi-pronged progeny study began in 1976 and ended in 1978. The results of this study show that the high percentage (10-20%) of the variance value of family × locus confirms that the GEI of Chinese fir is very significant. In this study, based on the stability of the genetic type, multi-point progeny determination of the families studied can be divided into three types, namely “fast-growing stable type” (20 to 25%), “variant” , “Slow-type” (20 ~ 25%). Our study demonstrates that the stability of the average value of the pedigree in Chinese fir families when measured in three different regions (with a common genetic control) is 0.691; however, when measured in two different regions, the mean value of the co-pedigree The stability is above 0.533. Finally, when the entire sibling progeny measured in two different regions, the mean value of family stability was close to 0.52.
