丽水55号,系自广西引进的阳塑9号无性系,由于在种子园中生长突出,参加全省多点多年重复育苗造林试验,三年生幼林测定结果同样表明,生长量均数达到极显著水平,与对照相比较,增产幅度在9.9~47.6%之间,最高达到51.3%;与初级种子园混合种子相比较,增产25.4%;与各家系均数相比较,增产16.8%,树高生长量遗传增益达15.7%,名列首位。它并具有适应性广、生长快、干形通直、抗病虫害、结实早、产量高、遗传性较稳定等优良特性,是值得推广应用于生产的一个优良家系。
Lishui No. 55, derived from the introduction of Guangxi Yangcheng 9 clones, due to the prominent growth in the seed orchard, to participate in the province for many years repeated nursery afforestation experiment, three-year-old young forest measurements also showed that the average growth reached a significant significant Compared with the control, the yield increase ranged from 9.9% to 47.6% with the highest reaching 51.3%. Compared with the hybrid seed in the primary seed orchard, the yield increased 25.4%. Compared with the average of all the families, the yield increased by 16.8% The growth of genetic gain of 15.7%, ranked first. It has wide adaptability, fast growth, stem straight, pest resistance, early fruiting, high yield, more stable heredity and other fine features, is worth promoting the use of an excellent family of production.
