miconioides accounted for 33.58% of the total genetic diversity while the genetic diversity among populations accounted for 66.42% as estimated by the Shannon index of phenotypic diversity, The genetic differentiation among populations of H.
      
The mean value of the genetic identity among populations of H.
      
miconioides was 0.7126 and the average of genetic distance of H.
      
The genetic identity between populations at the elevation of 990 m and at the elevation of 780 m was the highest.
      
The genetic identity between population at the elevation 500 m and other two populations was relatively low.
      
The correlation analysis showed that the genetic diversity within populations was significantly related with the soil total nitrogen.
      
Genetic analysis established that Aitaiyin3, a dwarf rice variety derived from a semidwarf cultivar Taiyin1, carries two recessive semidwarf genes.
      
pectinatum in Hainan were lacking genetic differentiation.
      
Genetic analysis indicated that it was controlled by a single recessive gene called ms157.
      
AFLP analysis of genetic diversity and relationship among some Chinese domestic ducks and wild ducks
      
The genetic distance (D) and similarity coefficients (GS) were calculated based on the polymorphic data.
      
A comparison of the genetic diversity in Dipteronia sinensis Oliv.
      
Based on random amplified polymorphic DNA (RAPD) markers, a comparative study of the genetic diversity and genetic structure of Dipteronia was performed.
      
These results showed that the proportions of polymorphic loci for the two species were 92.97% and 81.55%, respectively, indicating that the genetic diversity of D.
      
AMOVA analysis demonstrated that the genetic variation of D.
      
The abovementioned characteristics indicated that the genetic diversity levels of these two species were extremely similar and that the interpopulational genetic differentiation within both species was relatively high.
      
Analysis of the genetic distance among populations also supported this conclusion.
      
The correlation analysis between genetic and geographical distances showed the existence of a remarkably significant correlation between the genetic distance and the longitudinal difference among populations of D.
      
sinensis (p >amp;lt; 0.01), while no significant correlation was found between genetic and geographical distances among populations of D.
      
This indicated that genetic distance was correlated with geographical distances on a large scale rather than on a small scale.
