摘要
经过9年对红松坚果型无性系选择的研究,证明了红松无性系之间在结实量、结实品质和结实特性等方面有 显著变异,红松结实遗传潜力很大。通过多年调查和生物学统计分析,选出了丰产型、高产波动型和大果中产型 各5个无性系,为发展红松坚果园提供优良种穗、母株,为发展红松坚果事业奠定了基础。
Through the selection of fine clone for nut type of Pinus koreansis for nine years, the results showed that in every type of Piuns koreansis , there was notable difference between quantity of seed, quality of seed and character of seed and character of seed. And the seed heredity potential is very high. Five clones of each nut type respective with high and stable yield, big nut and middle yield, fluctuating and high yield were selected by investigation and biological statistic. It will provide optimal cuttings and mother plants for developing the nut garden of Pinus koreansis.
