The difference markedness of the content of potassium in leaves of tobacco seedling was checked up among different genotypes with the variance analysis method, and the heritability in the broad sense, genetic variation coefficient of the c.

The results are as follows:①The broadsense heritabilities of height,diameter and volume of cloned seedings are 0897 8,0831 4 and 0808 1 respectively;genetic variation coefficients are 1582%,1402% and 4112%.

The study indicated that genetic variation coefficient of thirty seedlings of 9major quantiative traits of mass crossing generations ranged from 20.

To cultivate the hyperprolific Large White Dam Line, the combination of quantitative genetics and molecular biological technologies was used.

population genetics and quantitative genetics, took nearly one century.

This review deals with the advances on quantitative inheritance of quality characters in rice, genetic models, statistical analytical methods, cooking and eating qualities, as well as milling and apparent qualities during the past more than ten years in China.

Primary problems of inherited parameter learning are analyzed and robust learning conception and method are presented.

Quantitative Genetics, Genomics and the Future of Animal Breeding;

This review will elucidate the cattle breeding progress in detail from five aspects including evaluation of conventional breeding methods, application of quantitative genetics in cattle breeding, computer technology and cattle breeding, genetic marker and its application in cattle breeding, and bio-technology in cattle breedin.
