摘要

'泓森楸'是由楸树4002与8611杂交选育而来,其年平均高生长量为3.8 m,年平均胸径生长量为3.2 cm,植株的树叶形状包含4002和8611两个品种的性状,速生性较4002和8611更强,遗传增益在30%以上,具有速生性好、干形直、冠形美、整齐一致、抗逆性强等特点。
        Catalpa bungei 'Hongsen' is bred by hybridization of Catalpa bungei 4002 and 8611, with the average annual height growth is 3.8 m, the average annual ground diameter growth is 3.2 cm, the leaf shape of the Catalpa bungei 'Hongsen' contains the shapes of 4002 and8611 varieties. The ability of growth of Catalpa bungei 'Hongsen' is faster than Catalpa bungei 4002 and 8611, whose genetic gain is more than 30%. In summary, the new variety has the characteristics of fast-growing, straight trunk, graceful crown, and anti-adversity and so on.
