油茶长林品种引进及综合评价

Introduction and comprehensive evaluation of Camellia oleifera ‘Changlin' cultivars

从江西引进8个油茶长林品种(‘长林3号’、‘长林4号’、‘长林18号’、‘长林23号’、‘长林27号’、‘长林40号’、‘长林53号’和‘长林166号’),开展了其在引种地生长适应性、物候期、主要经济性状、果实品质等试验研究,并进行综合评价。结果表明:油茶长林品种在引种地表现出了较强的生长适应性,物候期与原产地较为一致,产量和鲜出籽率等主要经济性状间差异显著,与对照品种差异亦显著。果实品质与原产地相比差异较小。筛选出综合性状表现更为优良的5个品种,分别是‘长林4号’、‘长林27号’、‘长林23号’、‘长林3号’和‘长林40号’。

＇ Changlin3＇ , ＇ Changlin 4＇ , ＇ Changlin 18＇ , ＇ Changlin 23＇ , ＇ Changlin 27＇ , ＇ Changlin 40＇ , ＇ Changlin 53＇ and ＇ Changlin 166＇ were introduced to Xiuzhou in Hubei Province from Jiangxi Province. The growth adaptability, biologi- cal characteristics, main economic characters and fruits quality were investigated and analyzed, further, comprehensive e- valuation were carried out. The resuhs showed that ＇ Changling＇ cuhivars showed superior growth adaptability. The main e- conomic characters of cultivars in introduced habitat were not significant different than those in native habitat. Fruit quality of cuhivars in introduced habitat was not significant different than that in native habitat. The superior cuhivars including ＇ Changlin4＇, ＇ Changlin 27＇ ＇ Changlin 23＇, ＇ Changlin 3＇ and ＇ Changlin 40＇ were screened out from the 8 cultivars.
