Variation and Superior Provenance Selection of Seeds,Cone and Nutritional Components of pinus koraiensis from Different Provenances
摘要
Abstract
Pinus koraiensis is an important economic tree species in Northeast China.Genetic improvement of its seed cone traits and nutritional characteristics can significantly enhance the benefits of related industries.Eleven 16-year-old P.koraiensis provenances collected from three provinces(Liaoning,Jilin,and Heilongjiang)were used as materials.The geographical variation patterns of seed cone traits(e.g.,cone mass,1000-seed mass)and nutritional components(e.g.,oil,amino acids)were analyzed to screen superior provenances.The results showed that all traits of P.koraiensis exhibited extremely significant differences among different provenances(P<0.01).The average phenotypic coefficient of variation and average heritability of all traits were 15.18%and 0.82,respectively,indicating high variation level and great heritability potential.Correlation analysis revealed that the mass fractions of protein,crude fiber,and linoleic acid were significantly or extreme-ly significantly negatively correlated with longitude.The mass fraction of polysaccharides was significantly positively correla-ted with July average temperature and sunshine duration.Most key traits showed a gradual increasing trend from northwest to southeast.Through principal component analysis,average membership function method,and Breeding's multi-trait com-prehensive evaluation method,Provenance No.1(Benxi County,Liaoning Province)was selected as the superior prove-nance.The average actual gain and average genetic gain of its key traits(e.g.,1000-seed mass,oil mass fraction,essen-tial amino acid mass fraction)were 22.12%and 19.52%,respectively.The results confirm the feasibility of provenance improvement of P.koraiensis,and the selected superior provenance can be used as the core germplasm for the construction of P.koraiensis seed orchards and fruit-bearing forests.关键词
