Analysis and evaluation of resin productivity and resin component among different half sibling families of Pinus massoniana
摘要
Abstract
[Objective]This study aims to provide scientific basis for the selection and breeding of high quality and high yield Pinus massoniana varieties, the genetic variation and correlation of main components of oleoresin and lipid productivity in semi-sib families of Pinus massoniana were studied.[Method]Pinus massoniana half-sib families of 20 years old in Nanning Forestry Institute of Guangxi were studied. Pinus massoniana oleoresin components in 48 families were determined by GC-MS.[Result]The results showed that highly significant differences in resin productivity and resin contained eight kinds of components, i. e. α-pinene, β-pinene, longifolene, caryophyllene, levopimaric acid, sandaracopimaric acid, abietic acid, dehydroabietic acid. The estimated family heritability for them was0. 654, 0. 625, 0. 697, 0. 532, 0. 408, 0. 344, 0. 575, 0. 295, 0. 477 and 0. 648, respectively, with corresponding estimated individual heritability of 0. 504, 0. 559, 0. 624, 0. 418, 0. 322, 0. 269, 0. 511, 0. 225, 0. 378 and 0. 589. There was a different intensity genetic correlation between resin productivity, α-pinene and longifolene, while a significant negative genetic correlation between resin productivity, β-pinene and caryophyllene. There was a significant negative genetic correlation between α-pinene, β-pinene and caryophyllene. There was a positive significant genetic correlation between resin productivity and levopimaric acid, while a no-significant genetic correlation between resin productivity and abietic acid. There was a significant genetic correlation between terpene and resin acid. [Conclusion]In the family resin-producing capacity and resin component selection, it is found that family resin-producing capacity ranking and alpha pinene, abietic acid, dehydroabietic acid ranking approaches, and beta pinene, levopimaric acid ranked relatively close. Superior families can be chosen according to different application needs.关键词
