化59—2是我所经过12年培育的新品系,它具有抗寒性强、速生等优良性状。该品系经过多年多点试验和生产试种,其抗寒性较为稳定,耐寒力已达到了93—114的水平,甚至茎基部的耐寒性比93—114强。一、培育过程我所于1973年用天任31—45作母本、广西红山II26作父本进行杂交,1974年9月用形态选种结合刺检流胶法选出,当年繁衍成无性系,1975年春首先参加广西容县松山前
59-2 is a new strain that I have cultivated for 12 years. It has excellent cold hardiness, fast-growing and other good traits. The strain after many years of trial and production trials, the cold resistance is more stable, cold hardiness has reached 93-114 level, and even the base of the cold than 93-114 strong. First, the cultivation process I used in 1973 as the mother of any day 31-45, Guangxi Hongshan II26 as the father of hybrids, in September 1974 with the morphological selection combined with the biochemical method selected, then multiply into asexual Department of the spring of 1975 first to participate in Songshan before Rong County in Guangxi
