Abstract


Two new big-fruit seabuckthorn breeds "Tefeng1" and "Tefeng2", belonging to Mongolian Seabuckthorn, were introduced from Russia and their real offspring groups were planted at Shuileng Courty of Heilongjiang Province in2002. In order to provide theoretical and material basis for real offspring breeding of good cultivars of seabuckthorn, the differentiation laws of phenotypic traits were studied when trees were six year olds. Several main conclusions were obtained as follows:(1) It was found that the phenotypic variations of hybrids progenies were obvious. The stem yield and numbers of thorns, viewed as two were found having the relatively big variation coefficients. The ratio of female to male was tested to be in accordance with law of independent assortment,1:1proportion.(2) Fifty-five hybrid individual trees were selected from real offspring groups of two introduced breeds. The selected fifty-five good stems present good100-berry weight that is an important properties. The fruit yields of some stems arrive at10000kg/hm2, showing good economic potential. The contents of Vc, Ve, flavonoids in fruits of the55selected stems all have obvious variation.(3) Based on the evaluation of100-berry weight and stem yield, three high yield and high-Vc type stems, five high yield and high-Ve type stems and three high yield and high-flavonoid type stems were selected.
