Abstract/Summary:
This thesis deals Wth 7 oil tea clones and their hybrization filialgenerationsl2 (according to 3 male cross 4 female). The random complete blockdesign (rcbd)is adoPted in the test. Camellia olefera Abol's importan economy tralts(tree body characters f tree high, crown breadth; fruit characters f frIJit high, fruit dia,seed ratio, kemel ratio, oiliness ratio etc.) and fatty acid compositions are studied.The results indicate f the trats of oil tea have great differences arnong the camelliaclones .Even, some differences come from clones' genes .Broad heritability is veryhigh. For examPle, seed ratios' maternal heritability is 0.83,oiliness ratios'heritability is 0.76.However,the other trats are influenced by environmentgreatlyHeritability is very small.For ExamPle seed ratios' parent interacionheritability is only 0.37.The clones' fatty acid composition is the other importantpart of paPer, mensurating the tfial 7 clones' and their hybrization filial generationsl2 and other suPerior clones' fatty acid comPosition with gas chromatogram.Gaschromatogram indicate: the difference among camellia oil fatty acid composition issignifican. The parents' soft grease acid, oleic acid, sub-oleic acid have greatdifferences. Broad heritability is very high. For examPle, sub-oleic acid's patrilinealheritability is 0.87, oleic acid patrilineal heritability is 0.9l,soft grease acidpatrilineal heritability is 0.69.Even, to the filial generation's infiuention is not samebetween patrilineal and maternal. For example, in kemel ratio, matemal influence isgreater than patrilineal influence. To the oPPosition, others influenced mostly bypatTilineal clones. In addition, there are significam correlations in a lot of camelliatraits, not only in quantity traits, but in fatty acids, in fatty acid and quantity traits.Some of them are significan.Breeding work can do in-depth part from knowing crop genetic background andgripping genetic law.ltwas notmuchto study camellia lmnort咖 economyproperties,especially In studyingMy acid co呷osltlon and estimating their broadbent劝illV ThispaPer studyelltirelyco呷tnotfillal gene佃ion andthelrparents tthe same time.The most lnPlnPo地以p瞅 Inthls thesis Is Studying camellia some tratsbent劝ility.In刎dition,it band together genetic law stMying and s叩er cloneselecting.R lsthe irsttlme to thetfee oil plants camellia.The results ofthlspaPercanglve science reference In selectinghlghyleld,high咖e oil ofcamellia....
